1. If BB is shoving like any pair and a bunch of random aces and like you seem to think then calling the shove is perhaps okay, but folding is certainly fine as well since we don't beat all that many pairs. This line from SB looks extremely strong and very much like his range could be weighted towards AA + KK although it probably includes like [JJ-AA AK] easy fold here since we don't haz odds to set mine or anything and are likely crushed way too often when we ship it in.

2. Looks ok, he'll ship a K and a flush draw pretty often. Given this is a BB vs BU spot though he can be full of shit here quite a lot and we should stack a K anyways, so I might just call here since we have Ah (reduced the amount of fds he can have and makes us less worried about shipping it on h turns.) Yah I'd let him keep bluffing and ship it in on a later street.

3. Preflop is marginal I'd fold since we're dominated by a good amount of stuff he's opening and are oop. Flop is fine, we pick up the pot a fair amount and fold out overs and pairs that are beating us. On the turn it depends how much FE we have. If we have 0 then betting is obviously worse. But I think he can still fold sometimes here when he has 88 and crap like that. We have a good amount of equity vs the range he's calling it off with so this is okay.

3. (2) I actually like the limp behind in this spot since this half stack prob wont fold preflop or to c bets as much as we'd like so isoing is kind meh I think although probably fine. We should ALWAYS bet this turn. Just because flush card has fallen doesn't mean we can't still get value from sets, overpairs and pair + spade combos etc. We need to protect here and are missing value from a ton of his range by checking. Yeah if you check back river you'd be reatdred lol, probably fold when he c/r since we essentially haz a bluff catcher. He probably doesn't do this with a 2 all that often. Bet the turn though for sure and consider folding to a raise since it's very often a flush in this spot imo (if he raises)

4. I can bet/fold this turn quite happily, again all we really beat is a bluff or a retarded top pair type hand. I think he's setted up here easily enough of the time for us to fold. You've bet the flop 4 handed on a board that misses a lot of your range, so your likely to get more respect and not get bluffed on the turn. It's a lol easy fold on the tiurn actually. If he cals the turn I'm value betting the river aswell because that's how you beat passive typical 10NL donks - value town them and fold marginal stuff when they take scary ass lines like in this hand.
