Pot-Limit Omaha, $1.00 BB (6 handed)
Limited time at the table, so not a lot of history with anyone. As far as I can tell, MP plays straight-forward and is a bit weak/passive. In one hand in the last orbit, CO checked a draw-heavy flop, check/called a blank turn and then check-raised all-in on a blank river.
Hero (BB) ($100)
Preflop: Hero is BB with 2♥ Q♥ K♠ 6⋄
UTG calls $1, MP calls $1, CO calls $1, 2 folds, Hero checks
Flop: ($4.50) 7♣ Q⋄ K♣ (4 players)
Hero bets $4.50, 1 fold, MP calls $4.50, CO calls $4.50
Turn: ($18) 3♥ (3 players)
Hero bets $18, 1 fold, CO raises to $72, Hero ???
My line was to play top two fast to charge my opponents when they inevitably pursue draws on such a wet board. Faced with a large bet on the turn, how do you respond?
