Outs counting, big pot and stuff (hand with lot of desicions) ...
 

At first - reads:

BB is 33/12/1 - LAG but not overagressive
UTG+2 is 27/12/1.7 - TAG/LAG but loose one
MP1 is 47/15/2.3 - clear LAG
MP3 45/15, CO TAG

My reasoning in blue.

What's your plan if the turn got donk bet or you got check-raised?

Re: Outs counting, big pot and stuff (hand with lot of desicions) ...
 

THe only thing I'd change is your potential line on the turn of calling a check raise on the turn and folding unimproved. If UTG+2 check-raises the turn, given the limp PF he was either getting overagressive with his flush draw on the flop and hit it on the turn, or made trips on the flop and decided to stop and go you. Either way, you're drawing dead, so I'd fold the turn to a raise here.

Otherwise the hand is good. The most questionable play is the flop 3-bet, but I think it's worth it for hand protection.

After some discussion I came to desicion to fold turn to any agression - to donkbet and to c/r for sure - risk of flush &amp; over is too high. Is it good?
