1. you didn't check flop and you couldn't check turn, wrong hand?
anyway you played this terribly, just call his donk and hope he leads .4 again on the river which you'll call
2. flat the turn, flat the river
3. he could have a set... how can he c/r you and have position on you?
but yeah I'm just going to call his bets
do you think if you raise him here you'll get more value? no, he's just going to fold
