What to do vs an unknown. Also how much does the backdoor flushdraw coming in change your decision.

With Ace-rag, and less than 12 bb, I generally like to shove pre because if you get flatted, your hand plays really bad post-flop. So, I suggest shove pre.

As played though, I like your flop bet, that seems standard. On the turn, his donk bet is rather bizarre because the only thing he reps here is A2, 34cc, 45cc, 35cc. I think there are enough draws in his range to justify a call here. I'm not happy about it, but I think I would just shove here and hope he didn't make some funky 2 pair. I would think if he were super-strong he would just let you bet turn because there is no reason to think you won't 2-barrell what you are repping (an ace).

Shove turn.

More importantly, shove pre imo.

fold pre

Reads on the 3 guys to our left are really imPortant as well as the rest of the table

I would grudgingly get it in readless on turn.

Fold pre huge majority of the time.

Give us some god damn reads son!

FD doesn't change much if anything imo. I like fold pre as well though. As played I don't think I'm folding.

Check flop imo. I guess getting it in now, but I don't think fold/shove are much different.

+1 forgot to say check flop

Mediums pairs are almost always shoved pre + if your tight and he's at all aware he has very combos that hit 76X boards and it's doubtful he tools out here. Check flop/decide turn

check back flop and go turn and river value

fold pre and you don't have to deal with this crap having ace-rag unsuited
