U'd be surprised how many games I lose like this or games when I lose when I'm in a better position.
I lost one game to terran 200 supply 2-2 to 0-0 to 130 supply because I Attacked up his ramp on shakuras and he had a ghost with two emps and 4 vikings.
However, I stopped throwing away games to terran because I stopped attacking in to narrow spaces and planetary fortresses.
Vs Zerg I feel like I throw away half my games after I'm ahead its fucking ridiculous dude.
I remember once a long time ago in beta I think, I was on 3 bases and maxed with colossus/stalker/zealot/phoenix, and he had 1 base and just took his nat, so i figured wtf, I should just kill his nat, so i kinda just a-moved in figuring there's no way it should matter.... I lost everything to tank + mmm + vikings, and then he came out and raped all my shit.
