Took a few months off from Poker. After losing pretty much my whole bank roll. Going to start off fresh. Post alot of hands and get as much help as possible. Heres a couple of hands from a sit n go I played today.
Normal table for these stakes variety of players few good few bad.

1st hand good fold? Anything else I should have done?

2nd hand was about 5-6 hands after 1st. Should I have just check/folded after the K on the flop? I did think with opponent limping then calling my raise could mean he had a big hand AA,KK, although if I were him in that situation instead of calling the raise I push all in. But I have seen alot of people at these stakes slow play big hands alot. So I wasnt sure. What seemed most likely to me was a small PP. I didnt think AK, because it doesnt seem like a smart play to limp/call a raise with AK. Isnt the best line to usually raise PF with AK. Not slow play like AA,KK. So on the flop I figured I should just push all in odds in my favor that he didnt hit a set.

Thoughts being AA,KK would most likely push all in PF.
AK would have raised PF not limp call a raise.
So I only have to worry about PP making a set on the flop.
Whats your thoughts, sugestions on these hands?
Thanks for the help.

1) Standard.

2) What were you expecting here? He folds, you take the pot. He calls, you lose to a K or a set. You probably should have check/folded here (to the push). He knows you will call based on pot odds if you have anything, and since you know he knows, you know he isnt' bluffing, therefore you can check/fold this. If he checks behind, and the brick hits on the turn, then you push. A King and a set bets that flop, everything else checks, and then their odds get reduced on the turn if they are drawing. A set can't risk a flush hitting.

I think you made the right move in both cases. If you lose in case 2 it isn't because you play it badly, it is just happens that your opponent had a K or 10 10. It won't happen a lot and usually you can take down the pot right there.
