[L][H] TvZ bronze v diamond muta harass

First and foremost your build order was a little wonky - you ended up having nowhere to dump your minerals in terms of army units because of your rax that were building addons instead of units, which left you with a CC's-worth of minerals floating for most of the early game. I suggest looking some more standard openers (10 depot, 12 rax, 13 gas, 15 orbital, factory @100gas, reactor on rax @50gas, hellion out of fact, swap, and double-pump hellions while making CC and more rax, or something to that effect) so that you aren't floating tons and tons of minerals with no purpose.

On a similar note your second ebay was ridiculously early. Did you have a specific reason for building it when you did, or were you just trying to dump minerals? When it comes to upgrade structures there are two styles: the fast double-ups (+1 wep/+1 armor simultaneously), which requires getting 2x ebays at the same time, and then there's 1 ebay getting one +1 after the other, then you add on a second ebay and an armory at the same time so you can get double +2's and a vehicle +1 at the same time. But your ebay timing didn't convey either strategy since it came well after your first, but well before your factory finished which would allow you to make an armory.

Honestly, you're better off getting ~4-5 rax before addons. You can get the xlab for stim since that takes a long time to research, but I've played TvZ's where I've gotten away without having reactors for the first dozen or so minutes of the game. You're better off augmenting your marine count earlier and getting more rax instead of spending gas on addons. You spent 325 gas on upgrades and addons before you even got a factory. That's just far too much gas spent without teching, unless you're planning on going MMM. To be honest you're better off getting factories and +1 upgrades rather than that many addons for pure marines in the early game.

However, for most of the game you had a decent worker count respective to your opponent. This more than anything leads me to agree with Demogonis: I don't think your opponent was Diamond, or even Platinum.

You had an issue with idle workers, at ~5:44 by your rax, and at about 8:46 by your depots, and again at 10:49 -- I suggest as a Terran that when you send a worker out to build, you always shift-click them back to the mineral line so that when they're done building they go back to mining.

On a similar note, you built 2 depots simultaneously in the early game and only had 1 rax with a 2nd building, and your first was getting an addon to boot. A depot adds 8 supply, and takes 35 seconds to build. If you're only producing out of your CC, you can only make SCVs, which take 1 supply at a time, and 17s to build. Therefore it will take you 136 seconds to become supply blocked assuming perfect macro. In 136 seconds you could build almost 4 depots one-after-another with a single SCV, which would add on 32 additional supply. My point is that 1 SCV is enough to build depots constantly in the early game without you becoming supply blocked. You don't need to use 6, or even 2, as you did at certain points in the game.

If you watch the Day[9] Daily, he talks about "extending the purpose," of structures and units. For instance, if you have to make supply depots (which you do), you can use them for more than just additional supply. You can put them near the edges of your base to gain vision over your main to become aware of drops, or use them to wall yourself in at your main or natural to defend from ling runbys, all of which extend the purpose of the depot, which is mainly there to get you additional supply. I see some sense of trying to extend the purpose of your depots by putting them out in your main. The risk of doing this is that they are vulnerable to drops and muta harass, or being blown up by banelings as they try to break in to your main/natural. But like Demnogonis, I don't think your placement was spectacular. Putting them that far out leaves them completely undefended. If your zerg opponent had wanted to, he probably could have blown a few of them up for free, which would have left you in a world of hurt. You're better off keeping the depots closer to your main CC / mineral line. If you want to set them out to see more of your base, that's good - but be wary about leaving them completely undefended like that. If you must put one or two out there, make a turret to watch over them, in the early game a turret will deter muta harass.

On a similar note, your ebay(s) could have been in the space on the high ground between your main and your natural CC. This is a good spot because its hard to harass there. Something to remember is that mutas come between 9 and 9:30 if your opponent is teching straight to them. So by 9:30 you should have an ebay up and 1 turret in each mineral line to defend from muta harass. I liked that you tried to pull SCVs to repair that one turret, and if you put the turret in your mineral line instead of out past the vespene geyser, you'll be better able to repair the turret and keep it up. As you get towards the 12-13 minute mark you should probably add 2 additional turrets next to each other on the outer-edge of your outer-most refinery (in this case that means putting 2 turrets next to the leftmost geyser in your main). This keeps mutas from blowing up your gas, and 2 turrets further deters muta harass to your mineral line, and then the turret in your mineral line is an added bonus. The later the games goes on the more those turrets are just to buy you time while marines run over to defend.

So if your turret was in the mineral line and your depots behind the mineral line or near the CC they would have been pretty well covered by the turret, making them less vulnerable to harass. Also putting the ebays on the high ground between the main and natural means they're defended from mutas because you'll have turrets in each base's mineral line which will keep mutas from flying straight by in most cases. So that placement alone would mean less running willy-nilly for your marines. When dealing with muta harass it's about controlling space, and minimizing your marine's travel time from place to place.

The last thing I'd mention is that at 9:22 most of your marines are exposed to the xel'naga watchtower's vision. This tells the zerg, "oh hey, his main must be mostly undefended!" Which makes them bold enough to muta harass freely. If you want to get map control I suggest leaving most of your marines at home and poking out with small groups to steal the xel'naga watchtower. In this case there were 2 lings at the tower and 2 between the tower and the Zerg's natural. You could kill those with 4-5 marines, easy, leaving the rest of your army at home to defend. The benefit is 2-fold:

1 ) your army can defend muta harass more easily because they're not out on the map
2 ) he doesn't know what your army comp/size looks like because he only sees 4-5 marines.

This was a major reason that muta harass began in the first place: if you watch the replay you'll see that when your marines are exposed to that xel'naga tower his mutas fly in to your base.
