Here are 3 replays of Jinro crushing TTOne's robo builds with variations of the Polt timing attack at MLG Dallas: Jinro Polt Timing Attack Replay Pack
I recently saw some guy using this build to great effect in a CraftCup Lite today, and it looks ridiculously strong. I've never played against this myself, but how do you stop a build like this if you plan to go Robo?
When you scout Terran, you'll see the Starport with a tech lab, which basically means that you need some sort of detection because of the threat of cloaked banshees. If you got the Robo for the observer, you need to get Stalkers to defend against the Banshee harass. However, there's still a huge Marine Marauder ball with this push, so you need to tech to Colossi. But then the push comes when you only have 2 Colossi and the PDD prevents your Stalkers from stopping the Banshees from killing your Colossi and then the MM ball destroys your army! @_@ <pant, wheeze>
Is there a correct response to this after you've already decided to do something like a 2 Gate Robo Expand?
