Looks good both post and pre flop. Neither of them were going anywhere on that flop so the check/fold saved you some chips.

I think it was either too much or too little preflop. Assuming they were decent enough players then I'd be content to call that preflop. The other option would be to push (I made a post about this tactic last week). A smaller raise would also be an option if you wanted to be aggressive post flop.

I think this one left you in a nasty in between land where you are not pot committed but losing the hand will significantly dent your stack. You've basically put yourself in a position where if an A or a K doesn't hit the flop you're facing a tricky decision.

8 times out of 10 I'd call that preflop the other 2 I'd push. More info on the player might change those stats

i just call that pf. you only pair the flop 30% of the time, if you want to raise, you have to go all in.

in these SnGs I think calling, raising to 200-300 or allin are all ok. Flop play is fine.
