Looking for input everywhere on this from ranges, tournament life, bet sizing. It seemed pretty simple at the time and still does...but I've just been thinking about it.
Blinds are 75/150 no ante.
Stacks:
Hero: 19,500
Villain:9,600
Villain is an older-gambly type of guy. I believe I've seen him play $2/$5. Plays a lot of pots. Puts pressure post flop. Limps in from any position. Raises 4.5x - 6x with big hands pre.
Villain is UTG and limps. I put him on a range of small to medium suited aces, A10o-AQo, small pp's up to 7's and KTo - KQs.
Another 2 players limp.
Hero is in SB with A

8

and completes.
BB checks.
Pot:750
Flop: 8

Hero checks. I checked because I thought betting into 4 players looked really strong and I felt like villain would bet and I would go for a check raise.
Villain bets 400 - he can have anything here...weaker aces, KT, flush draw, straight draw, combo draw.
2 folds
Hero check raises to 1,500
BB Folds
Villain instantly ships
Hero?
Just by the speed of the ship (live tell), I believe him to be squarely on a flush draw. This type of player, from my experience, tends to want to shove people off of hands with draws and would min raise a set or huge made hand.
My image at this point is a TAG..but I don't believe that plays into his decision making process at all as the shove was so quick. No results
