Assume you're playing a standard villain that is reasonably aggressive but not a maniac. Blinds are 15/30 with full stacks.You raise preflop with J2o and the flop is 6dJd9h and you bet 60 into 120. He raises to 180, what do you do? If you shove, you might fold out some draws or 9s but you're mostly getting called by better. If you call, he can bluff any straight or flush card and you're in a tough spot. If you fold, it can be pretty exploitable. I know one solution is to not play J2o preflop but the same situation can occur with K2o and it generalizes more than that. What are your thoughts?
I'd fold on turn bet, if it will be normal size bet (not 1bb bet or something crazy), just to not play huge pot with 1 pair hand without kicker. Yes, he may bluff you, but if you dont have other reasons to not fold, you should fold. What kind of reasons you may have: a) With shallow stacks, it's more logical to not fold on turn, because pot size already big, comparing with your remaining stack.b) Also, you may think about his hand: some people will 3bet AJ, KJ, some people (mostly regulars) will not c/r flop with QJ or JT, because "you will be called by better Jacks, and kick-out worses"... so there are not so many Jx hands.c) If you have information how he plays his draws (donkbets, c/c, c/r?), you could change your play. If you know, that he is capable to c/r you with OESD of FD, it's probably better to check behind you weak top pair on flop. If you have Kx, it's even more reasons, because it's only 1 overcard may come on later streets.d) How many hands you open and he calls OOP? How often you contbet and he folds?I just say that if you wish to make good decision in a tought situation, you must think about many factors. And you need to have confidence, because if you scare of any villain's action, it's better not to play.
Standard readless play is to just flat call and reevaluate the turn.
Otherwise, you base your action on how your opponent plays and adjust properly (reraise can be the best option vs certain players).
A lot of "scare cards" on the turn also turn villain's draw into a pair, and he will slow down on those cards. People suck at v-betting thin.
