This is from a live tournament, kind of early stage but after the late reg and reentry phase. I've played with CO for the first time, and I can only say that he seems decent/reasonable, but nothing special.
UTG: 27 BB
CO: 75 BB
BTN: 140 BB
Hero (SB): 42 BB
BB: 12 BB
5 players post ante of 0.1 BB, SB posts SB 0.5 BB, BB posts BB 1 BB
Pre Flop: (pot: 2 BB) Hero has A
A
fold, CO raises to 2.5 BB, fold, Hero raises to 7 BB, fold, CO calls
Flop: (16 BB, 2 players) K
T
9
Hero checks, CO bets 10 BB, Hero goes all in
Now I know that this shove is terrible, but I'd like to know what is/are the correct play/s. My guess is bet-fold is best, but probably check-call flop and check-call on safe runouts (safe means no Q, no J, no K, and no clubs) is fine, too. What about just check-folding the flop? Is that too nitty?
