I think I just kinda blundered through this hand. I should've likely just been CBing and getting AI if neccessary, and I checked back OTF because the SPR allowed me to get AI on the next 2 streets, but I just lost my nerve after the 3rd flush hit. I really considered shoving OTR, but villain #2 all of a sudden betting kinda raised my eyebrow, and despite the small sizing I decided not to go for max value:

UTG checks, UTG+1 checks, Hero checks

River: (t1275) T (3 players)
UTG checks, UTG+1 bets t250, Hero calls t250, UTG calls t250

not the board to be checking AK as PFR...

bet 650 so to shove turn

as played rest is fine though I agree it feels pretty silly

Preflop: standard

Flop: Bet?

Turn: Fine here I guess, don't like a raise/fold if 3 bet

River: Call is fine I guess?

I don't know, I'm thrown off with the flop check..

You are much better than I, but why the check back on the flop? What do you mean by 'SPR'?
