Hand 1: I would fold. Unless you have reads that say he is an aggressive player, odds are you are either up against 33, 88, or a flush, although i could be possible he is playing with another king. if that is the case, you are looking at either ak, kq, or maybe kj?

Hand 2: Again, fold imo. This looks like one of your average slow plays. small bet on flop, calling a raise. c/c on turn and open pushing the river.

Hand 1 - Fold, your only beating Kx lower than KQ and would SB call a big raise OOP with anything like that? Doubtful, unless you have reads he's a loose fish. Much more likely a flush or set turned boat here. AA and QQ would likely re-raise preflop. JJ-99 is a possibility preflop but unlikely given postflop action . A read of some kind would be helpful but without one, im folding here.

Hand 2 - Id fold preflop. MP1 raises small even with 2 limpers, that can mean a monster he doesent want to scare everyone out with or maybe a PP/SC? Dont like the flop re-raise here, your building a big pot with top pair average kicker. When he calls im done with the hand. I would check the turn and fold to a bet. Fold the river... please, he's given you good odds to call the river bet, but ask yourself, what do you beat? a worse boat and A high? both of those are highly unlikely id say unless you have reads hes a total donk.

Hand 1). i agree with the above advice

Hand 2). go ahead and float your TPWK on the flop, if villain is a habitual c-better. It is okay to fold TP in this kind of spot IMO, since i am guessing you called preflop with the goal of flopping either a strong hand/strong drawing hand. Since you didn't i think you should let go of the hand before the big bets start to go in.

As played, you need to fold on the river.

hand 1: check behind on turn

hand 2: fold

How do I check behind on the turn when he bets?

umm wtf???
sb checks hero bets. how do you check behind idk maybe click check.

Sorry, my bad, was looking at the flop.

Hand 1) why bet the turn, let's see the river? CHECK, for pot control and the ability to call a decent river bet should villain bet out first. As played FOLD.

Hand 2) Since you chose to be the hyper-Aggro: committing 50% of ur stack, CALL, but be prepared to see the OverPair (JJ)?

Hand 1. Im folding, unless he is a complete idiot.

Hand 2. Fold, you are up against TT or JJ (or at very least a9s) imo.
