Bisu had a disastrous PvT performance following his exit in the recent ASL Season 10 Ro24 group A match. His decisions at times were questionable and his unit micro as well as tactical awareness were poor.
The below is a simple breakdown on his mistakes and what he can do better in the PvT matchup.
Versus Leta matchup:
1.Wrong Targeting/ Unit Micro Bisu's unit micro was questionable at times. Zealots should be targeting tanks, not vultures, and he should pull his dragoons back when he couldn't break the tank lines.
2.Opting for recall first instead of stasis Usually, when the Terran goes for a timing attack, it is always better to go stasis first to limit the Terran push. Recalls only work when the Protoss is practically ahead in the matchup where he can then sacrifice the recalled units to deal damage to the eco, main or natural.
Versus JyJ matchup:
1.Wrong Targeting/ Unit Micro Again, zealots should be targeting tanks, not vultures, and he should pull his dragoons back in time.
2.Carriers flanked by Goliaths Here, Bisu's carriers were being flanked left and right by JyJ's goliaths, which proved vital in reducing the carrier count.
3.No HTs/ Storms Often, storms are used to break the Terran contain. A bit surprising here to see Bisu not opting for HTs and storms, or maybe he was too late as they could be invaluable in breaking the Terran push together with carriers and gateway units.
Vs Leta 1) Bisu was behind army-wise, he should have not commited to the attack. Even with perfect micro, I do not think he would have won that engagement. He needed to buy time, make Leta siege-unsiege untill he could muster a greater force, or his stasis had finished researching.
2) Most likely Bisu researched Recall before Stasis. Probably he did not have Statis available. Anyway, it was a desperate move at that time, he was so dead.
Vs JyJ
1) That attack felt unorganized. The Carriers came a bit late, the Zealots and Dragoons didnt work in sync. He didnt have the patience to carry out a proper fight.
2) Yeah.. attacking JyJs base from that angle, not doing any real damage, and getting flanked, a desperate move.
3) Maybe, but he was so screwed from 1) and the consequent push, probably didnt have the economy for it.
Even from the beginning, I don't understand why he'd go for a proxy robo against leta. Leta's tvp isn't great (especially on that map) and it feels like Bisu should have just played standard (maybe eco greedy because of the map).
vs leta he went 12 N into proxy robo, big gamble, his robo got scouted and then he had no obs and leta took map control with mines, the rest doesn't matter as much, he was behind from the start
vs jyj going carriers in close positions is a big gamble as well, he got scouted again and his engagements weren't great as the OP said so game over
vs Leta #2 Bisu had already lost, this didn't matter.
vs JyJ #1 I'm not sure why Bisu attacked at all. To me that's more important than the zealot positioning. #2 Bisu had already lost, this didn't matter.

The proxy robo is Indeed strange. Bisu saw 2 marines so at worst he could have faced rax fe. Why not play safe, 12 nex is a huge advantage for toss and with even without obs should be alble to punish fact triple...
Game 1 : Bisu's robo was scouted, Leta destroyed it and went -> Vulture -> Mine -> 3ple Command to punish lack of observers.
Is really difficult to come back at this point 3 base vs 3 base with protoss 3rd delayed.
gg
game 2 : Bisu has been playing Carriers in practice and spon matches like 90% of the time since polypoid came out... JyJ knew that min only expo is bad vs carriers cause u can't produce enough goli in time to stop 4 carrier timing, so he timed 4 scans to confirm carriers and if no citadel + 2ble stargate he would take his gas expo as his 2nd natural.
Willjay84 my dude, I think you have the best intentions, but much like your "possible counter to 973 hydra bust" thread you just clearly don't really understand the fundamentals of the game. I appreciate that you're wanting to put in effort and be constructive, but unfortunately I just don't think you're a good enough player to do so correctly.
Bisu's proxy was a high risk, high reward situation. With a backdoor expo oriented towards his main I think it was just too tempting. Conversely, going for a quick third behind mines Leta knew he'd suffer from reaver play, plus he saw a single gate and it just made sense - would Bisu go for a quick second gate and range in this scenario on this map? He has nothing to pressure. Robo tech made a lot of sense and I still think he was just going on an intercept when he found the robo.

Bisu has some of the worst Carrier control out of all Protoss. As soon as I watched the game and saw Bisu going carriers, I just facepalmed and expected JyJ to win after that.
Game 1 can be explained by Bisu falling incredibly far behind by losing his proxy robo. Leta already knew what was coming after he killed the robo and he got his 3rd incredibly fast. Bisu was on the backfoot the whole game from that point forward, I don't blame him for losing that one. Did he need to proxy? No.
Game 2: Bisu carrier. In the same way that Best's corsairs are nicknamed "Doh-sairs", Bisu's carrier control should be nicknamed something like "Taek carriers". Also, Bisu's army control in PvT for whatever reason has been historically awful. Realy bad engagements, poor micro within fights. He really should study replays from Stork/Best/Rain to understand how to successfully take engagements in late game PvT.
lol guy in the chat :he microwed wrong look!: what actually happened bisus proxy robo destroyed proxy robo did nothing put him miles and miles behind also no obs for 10min k thx guy in the chaaat!

bisus carrier with the signature 4zealot shuttle drop to take down turrets fast / harass actually made quite an impact on the scene took down flash among others :-) (pre army) I think your analysis is often very inaccurate but obviously he didn do well this time or after return from military service how ever u wanna see it

I've never been impressed with Bisu's carrier control. Maybe my memory is wrong but every time I watch him use it, I'm watching him fail miserably and wishing that Snow or Stork were playing instead.

Speaking of carrier play, I cannot encourage you guys enough to go watch set 4 of recent UBE event Snow vs Flash Compared to Bisu's Ro24, it's day and night. Instead of throwing away units for free, Snow is very patient, and does an incredible job at keeping his ground army just out of range of the tanks, so he can slow the push, snipe some tanks, and instantly jump on any goliath chasing his retreating carriers. Really impressive stuff.

See, this is why I'm confused about Bisu's carrier play. He's so good with reavers and corsairs as harassing units where he picks off units bit by bit, but how is he bad with carriers when they function very similarly? Snow played this game really well and his carrier control impeccable.
The reason why I didn't count Bisu's failed robo proxy as a mistake is because it was a gamble. A gamble always works 50/50. Hence, when his gamble failed, he fell way behind without observers. To make things worse (from his matchup vs Leta), his bad engagements with zealots and dragoons against tanks and vultures and bad decision making for opting recall ahead of stasis where had he gone stasis first, and didn't lose gateway units unnecessarily, he might at least put up a fight though Leta might still have won with 3 base vs 3 base and superior macro.

Proxy robo is a mistake itself, 12 nex against fact expo is a huge lead. If you just play safe with observer first Terran cannot go 3 cc on 1 factory.

I agree. Bisu was under no pressure to try to go for any risky play.
Bisu didn't lose the game through his micro mistakes, which we can point out, but from the robo. I think after that critical error in build order choice it's pointless to analyze the game unless Leta makes equally similar mistakes. At this professional level, Leta should take a comfortable macro game and roll Bisu, knowing that any 3rd base Bisu would set up is delayed, mines prevent any counter attack, and reavers are too late by the time Leta has turrets up to protect.

the control doesn't matter when you're behind in army and production the way bisu was, you can point to his units hitting the wrong thing but the reality is that no amount of carrier micro is going to stop goliaths when you're down 40 supply
yes, technically the screenshots you posted were examples of him not engaging optimally, but no pro player plays every engagement perfectly -- you can find micro and engagement inefficiencies in just about every single game
bisu has in general been sloppy and not as great as the bisu we remember from his peak years. maybe thats why he felt the need to take a risk with a proxy robotics, who knows.
Today he played vs Light in KCM, opened Nexus and also made a proxy robo. It wasn't scouted, he got the Reaver, but didn't do much damage. He didn't suffer for it at least. He was up in supply and when he reached 200 he attacked T line behind Supply Depots. He lost everything, the supply evened, and from there Light was a bit in front and won in the end.
My question: what was he supposed to do at 200 instead of attacking? Bank on resources and let Light grow even more? He did open Nexus first and some say that it is a massive advantage, so what was he supposed to do to capitalise?

Do you have a link? Without looking at the game it's hard to tell. Protoss can always deny bases and keep expanding/teching, or probe the front and recall somewhere else. But a protoss attacking an already entrenched Terran behind a wall sounds like a terrible choice.
I also feel like I'm missing something hearing folks complain about Bisu's choices to do ~200 supply timing attacks.
It seems to my naive eye like there are often probing attempts to recall, keeping a terran honest, but if the terran spends enough on recall defense then attacking the front is perhaps the best approach one has at doing realistic damage before a terran reaches 200/200.
Now, it is often proposed that protoss should sit back and get more bases/gates/storm rather than attack into terran 3 base defense. It looks again to my naive eye like this is an extraordinarily difficult path to take, and that a protoss is not an idiot for thinking his best chance to win is never to let a terran reach 200/200 with 3 attack upgrades.
Consider for example the following recent game of Bisu:
It looks to me like Bisu makes a very good attempt to play the "sit back and macro" style here, rather than attacking. When Flash pushes out with 200 supply at around 19 minutes into the video, Bisu also does an excellent (and imo very difficult) job of preventing Flash from taking additional bases during the terran push. He does this masterfully with a single reaver, and even holds off the first 200/200 terran attack with storm while holding another main. Nonetheless, he is unable to hold off the inevitable and Flash eventually secures additional bases with the superior terran max supply 3/3 army to win the game.
What am I supposed to be thinking when I see protoss lose games like this, other than that you must kill a terran before max supply and max upgrades?

Recalls were tried, but didn't do much. So the question is - how do you play that position?
Maybe somebody else with more game knowledge can explain better, but to me that just looked like a total suiciding of units at 12:30 (attacking into mines + a wall + sieged tanks + turrets) where he traded away his entire army for 6 tanks and like 10 vultures, and then proceeded to recall in the same spot three times in a row on top of mines and tanks. I'd be pissed if anybody were able to win a game from that position tbh. Even then I felt like if Bisu hadn't tried another recall just before he could've cleaned up a lot of Light's army at 18:30 when he pushed out . So I guess to your question -- don't throw away your army multiple times? Hopefully somebody else has a better explanation because now I'm just as confused\ why Bisu played the way he did, it just seemed like throwing away units for his first big attack.
EDIT: looking at that fight again he still had half his zealots going around the supply depots when all the dragoons died lol
It would be good to hear from someone knowledgeable: 1. would you recall as Bisu did 2. would you attack in full as he did
And if not, what would you do differently? Banking up? Waiting for Light to move out with 200/200?
Keep in mind that Nexus first should be a significant advantage for Bisu, as some have suggested. Light should not be in a position to be able to win by just sitting back and doing nothing - if who could do that, Nexus first is not a big advantage (and yet it is a big risk).

I think you have some good points here that people won't want to acknowledge because they want to believe the fairy tale that every aspect of this game is perfectly balanced.
I wouldn't call PvT imbalanced. I do think that unharassed T of an equal level obtaining 2/1 and pushing out will look imbalanced, but P has other aces in their sleeve for rushing or pressing early (so does T). If T is playing perfectly, I would say it has an advantage, but nobody plays perfectly all the time.
However, I am insterested in this specific game. Bisu is economically ahead, and all Light is doing is still staying back and macroing confident that he can win that way. This I don't appreciate much. Nexus first is a gamble for P, you can so easily lose to a push, but if you pull it off, P should have the advantage. The ball should be in T field.
Bisu had a 50 supply lead when he commenced his horrid attack in the wall of supply depots. Even if you feel like you need to pressure the Terran in some way, that is definitely not the way to do it.
Bisu should just be focused on getting more tech, grabbing all the bases on the map as soon as he hits 200. When he attacked, he only had 5 bases and no 2nd set of gateways. If you want to keep Terran back like that, you need recalls, or just an overwhelming hoard of gateways/bases and play almost like Sauron Zerg style of remaxing ASAP and then trying ot whittle down the Terran force.
Also, when Bisu sees that massive supply depot line, it should signal to him that Light is going to turtle. He sees this with a couple zealots at 15:00. I think a double expand then, and then adding more gateways is best. Then, Bisu should try to wait for Light's push and right as Light's army gets across the depot line is when Bisu should pounce.

I also don't really believe the game of broodwar is "imbalanced" at the level of the whole game on ever-changing maps. I just want to emphasize that Bisu's 50 supply lead at the point of attack puts him in a unique position where his army will be strongest relative to Light's for the rest of the game. If Light moves out from behind supply depots a bit later, does the lack of protection from the supply depots actually make his army 50 supply weaker? If not, do the extra gates and bases really get leveraged into a win?
I haven't actually been convinced that sitting back and grabbing more bases is worth more than lowering the tank count at the point the protoss army is strongest. The fact that pros like Bisu and, previously, Rain, immediately go for these attacks seems like evidence that they are reasonable, rather than unreasonable. I'm 100% sure Bisu is aware that Light was attempting to turtle behind supply depots when he decided to attack, and he did even manage to lower the tank count despite suboptimal micro.
But neither Bisu nor Rain is very famous for their PvT, only for their head against brick wall play in the matchup. Rain's macro sometimes made it a good strategy for him but you can absolutely be a good engager in PvT and neither of them is.
In my opinion Bisu has not been playing significantly worse lately than he usually does, in fact rather the opposite. I think he's improving quite rapidly. This whole theorycrafting in here about the once fastest and most revolutionary protoss player is hilarious to me. Does anyone here actually believe they can criticize Bisu's tactical decisions? Ridiculous.
PS: That isn't me saying Bisu is beyond criticism. But please that's the job of the top pros. Any top pros in here? I think not. That should settle the debate I think.

I would be doubtful of the outcome. Bisu pulled a Nexus first. By allowing a 200/200 T he is putting himself in a position to die from a single positional mistake during the T push, irrespective of his number of bases. In my opinion, P has a small set of options, none really being the best to punish a purely defensive T which should be behind after P went Nexus first. That being the case, it's clear why Nexus first is so rare.

Idk how much insight you have into Bisu but he's an emotional player, I guarantee you he felt the game was already lost after that failed proxy and only played it out cuz it's a tournament setting. I would absolutely consider gambling vs a player weaker than you a big mistake (Bisu was heavily favored in both the matches he lost, at least in my opinion). I don't know why he did it but I imagine it was because he didn't feel too well or prepared (I know his few streams prior to the matches were of him drinking and partying and not even touching the game). A gamble is never 50/50 btw there's a thousand factors to consider as well as weighing the risks vs the rewards, this is the kind of stuff that really separates the boys from the men in terms of the strategy aspect of the game.

I tend to agree limiting Terran tank count is important but big supply depot line is really hard to break and that means even with 50 supply advantage, you're actually probably down in supply. Rewatch the attack and seeing goons get stuck attacking the depots and zealots clumping together, getting stuck on each other trying to get around the depot line, Bisu's army might as well have been down 50 supply instead. You need to take what you can and in this position, the supply count is deceptive because of the wall.
