1). villain isn't very aggressive so it's unlikely he has a draw or is bluffing. he's also very unlikely to fold a pair of jacks on the flop regardless of what we do, since he's a fish, so we can assume we have almost no fold equity. So the first question we ask ourselves regarding whether to call/fold to this check/raise is do we have roughly sufficient pot odds.

about 9 to call, about 21 in the pot. Our hand (11 outs versus J-x, his most likely hand, 8 against 4-x) has around 40% equity so it looks like this is a pretty easy call. Sometimes when the answer isn't so clear we have to determine whether our hand has sufficient implied odds (can we make an unprofitable call on the flop because this fish will pay us off huge every time we do hit our flush?) or whether we have to worry about reverse implied odds (if we do hit our flush, do we only get our opponent to put more money in the middle when he has a bigger flush/better hand?).

2). without any postflop reads i would fold the turn. preflop/flop are good.

1) standart fold
2)Fmakk is 20/13 with 3bet of 5.9 over past 2k hands.Fold turn, this villain gives up without a hand after 3betting pre. Flop he can cbet w/AK, but he won't 2nd barrel with it most times.
EDIT: whoops, i thought he 3bet pre. my bad. Not that it really matters though, so my OP does not change.

1) You should only fold really if you strongly suspect he's got a 4 - as then your draw has much less value here (full house poss)- but since hes not an agg oop kinda guy then why suspect him of a 4 judjing by his pf actions? call, he'll probably crap himself if an overcard falls anyway, then you get a free card. no value in raising btw

2)its quite close i think he could easily just have plain overs. my foolishness wants me to raise hehe
