Most don't have a clue at basic theory live in the games I've played. It's pretty easy to spot who does. Saying that I got stacked by flopped nut flush and rivered nut flush last week when I played at MC last week so what do I know
Had a mare on Sunday. Went into FT with 1/4 of the chips in play, and wasn't much worse off when it got to 6 handed. 3 big stacks, 3 shortstacks. Idiot big stack then proceeds to start doubling up all the shortstacks with absolutely no need to postflop and preflop (calls utg 20bb shove from BB with Q9os when she had like 80bb, c/shoved 1082r board with J7 when villain shorty had half his stack invested =/). KK cracked by 87os aipf by shorty who raised half his stack utg!, 1010 cracked by river when floated on 235 flop with AJ (shouldve bet K turn though, didn't change anything
and hits alot of my flop bluffing range), then JJ cracked aipf by KQ.
Annoying didn't quite cut it. Not so much the beats, just the totally moronic play by one of the other stacks making it stupidly difficult when the 3 of us could have sailed to the money.
