I guess the title might say it all.

$200 NL, Very LAG preflop table, action is revolving around one fish who is taking 1-pair and weak draws way too far in hands. He still plays pretty reasonable facing big raises preflop. This hand turned out all sorts of weird, I'll try and explain as best as possible

Straddle pot
-Several limps to Fish (85BB~) on button who raises to $14
-I have AA in SB(180BB)... 3 bet to $28 looking to keep the fish in and get his stack if he flops any pair.
-An early position short stack jams for $39
-One loose MP Limper (180BB) Calls
-Fish Calls
-I can only call
-$*&@

Flop 5 7 5 Pot $160
Effective stack $320
Fish Stack $135

Check/Bet/Sizing/Why?

Preflop is where you went wrong. Multiple limpers to fish who bets 14 and we minraise? Knowing there's a shortstack who, if he shoves, closes the action makes this worse.

3bet should be 40-50, lower end if you are concerned fish will fold to 50. Rest is meh, I'm shoving the flop.

Edit: Add the fact it's a laggy table, minraising pre should not ever cross your mind.

Don't like how you played it. Should have raised to $45 preflop.

AP - I think you can feel good with this board as I don't think you are against a 5 year. I bet $200

With a LAG table and multiple limpers to the fish, I'm surprised by the min raise. At least make it 42, especially with the short stack there knowing he might shove and raise block you there.

On the flop I doubt there is a 5 out there so bet big and get the draws out and try to end it right there because you are most likely ahead at this point. You want the pot on the flop and get out of this mess that was created preflop.

Yeah nobody folds to 3 bets live. Need to make it like $45 pre. I'll bet smallish otf like $55

3bet bigger.

$60 on the flop.

$60 on the turn.
