I checked the turn to hope he either would bluff at it on the river and/or catch something. Checking the turn typical here?

I really only fear a slow played KK as K4 would have probably popped it already and 55 and 66 seems very unlkely. I checked to induce a bet but do you raise when it comes back to you? Do you just lead out?

I know I said I don't slowplay but if there was ever a time for top set, it was this flop. Comments?

Well, I was worried about getting money into the pot but I just pushed it afraid I was just gonna win it right there. I can't believe what called me down. When the river hit, I thought I lost it all but at least I got the side pot.

Hand 1:
Your options are really a small bet on the turn and/or a small bet on the river. After he didn't take the bait on the turn I'd maybe try about a $1 river bet. Betting pot is OK too. You have to put yourself in his place, imagine what he might have, and tailor your bet accordingly. Here he's either got nothing or a backdoor flush, so you're not getting paid unless he has the latter - will he call a full pot bet with it? The only other variable is how much (if any) he'll be wqilling to call with a real garbage hand - some people will call a small bet here (50c, $1 or whatever) just to keep you honest or out of pure curiosity as to your hand. This is why I normally bet a bit smaller when it seems almost impossible for them to have a decent hand. Others would disagree and plump for a full bet. I suspect in reality the difference in EV between either move is negligible.

Hand 2:
Flop check sucks. Don't give free cards to overpairs; if each player had a pair in hand, you gave 6 outs a free card, almost tantamount to giving free cards to a flush draw when you hold a set. I wouldn't check the river to induce a bet unless they're the type to bluff; you're probably up against either overpairs or busted draws, again I'd just lead out normally for maybe 1/4 to 1/2 pot and hope to get a call somewhere.

Hand 3:
Yep, this is OK I think. Against decent opponents I'd even like to throw in a deceptive min raise here; make them think you're on a low wrap, let them raise their underset or two pair, then raise or check-raise all in on the flop. A similar strategy might work at 25PLO but it's by no means routine. I think your play was OK, I think you can't risk another freeby on the turn.

Hand 4:
Seems routine really. Well played.
