1) can't really imagine playing it any other way, maybe calling turn to trap but that's FPS on that board, shoving is probably best.

2) I probably call this turn but i make a lot of loose calls like that. depends a lot on the opponent in question but fwiw, villain's line seems innocent enough if he's a typical player that you shouldn't just assume you're beat.

3) meh, I like shoving pre or 4-betting and calling a shove. gotta call sometimes too though for balance. as played can't really go wrong here, i'd probably shove b/c I put my stack in more than most, but there's nothing wrong with calling. again, balance, figure out a way to work it into YOUR game taking into account how this guy is playing. Doing something gay like min-raising is another option.

cliff notes: you can't mess this up; don't do the same thing every time

4) hard to analyze this one, depends a lot on what kind of range you put him on and what kind of range you think he'll call a shove with. ie. if the 2 barrel means that he has a king or better nearly every time and you don't think this 43vpip idiot will ever fold a king, this is bad. if he's very aggressive but wont put his stack in without the nuts, it is splendid.

cliff notes: putting your stack in as a semi-bluff on the turn is balla, keep it up

5) first impression was GROSS, and how do you NOT 4-bet this pre? after learning of said player's nittiness, i think this is fine.

6) i don't mind a raise pre sometimes but completing is probably the more generally accepted play. easy shove on the turn, he's got like 20 back in a pot of 50+.

7) your line seems oh-so-weak but given stacks I don't hate it. This seems like a v. good spot to lead the flop, puts the button in a very tough spot and you in a very good spot, also great for metagame and getting action on your sets/combo draws.

cliff notes: i mention combo draws because it's fun to go all-in with a draw and suckout
