He probably had 40 OCs built/building at the end. I actually do that strategy a lot, though I've never build 20 OCs at once in a real game lol. Was he saccing SCVs at the end, because a huge strength of that strategy is being able to have more army supply by relying on MULEs for minerals and only keeping some SCVs for gas.
I used to primarily play MTTs. So frustrating. I used to call it all the time, obviously except the times it didn't happen, where the last card always gave the worse hand the card it needed - and that was internet poker. Seemed like it always happened the most right at the bubble (i play for the bubble!!!) or at any pay jump. Obviously variance, but still, to see it in live poker isn't as bad, but geez, brings back so many frustrating emotions.
