assuming no reads :

1- yes

2 - maybe. bombing non-heart turn could make more in long run (since you are hoping button has aa/kk). then again if he can't lay down overpair it's fine.

3 - interesting one. if you think he is calling with a pp and basically saying "prove to me that you have a better one", turn check-raise is sexy. if he's on a draw, checking sux. i think your like is fne though. I'd prob vary between check raise and bomb-lead.

4 - 3 way protection is funner w f draw on board. despite this, a raise that pot-commits UTG+1 might make more in long run since he could conceivable (donkishly) call with more hands that you beat and then be pot commited by the turn.

5 - love this line

6 - hmmm. value bet will prob get called way more often. in this case I think a smaller bet is more +ev unless villain likes making hero calls and you are trying to rep a busted flush/combo draw. I think he calls a 1/2 ish pot sized bet like 100% here if he doesn t have air so I like it better. I think he folds too many hands to your line unless he is pretty aware. Assuming he has something like ak/kq calling the push is tough. then again, repping busted draw... hmmm. i m torn.
