Grunch:
Turn seems too small of a raise.
V is betting pretty big the whole way through. 3/4 pot on the flop, 3/4 pot on the turn so there's a good chance that he has a hand that he likes, and you raise him only $250 more. I'd be looking for fat value here. After you call his turn bet and before you raise there is $600 in the pot.
You raise $250 more, giving him 8.5:2.5 on a call, ~3.3:1. A great price for any set, a great price for any flush draw (and hes IP on the river which makes it harder for us) as we're going to be hard pressed to fold to reasonable river bet, and you're not really setting up your self up to play for stacks on better river cards. I.e. most of the deck that's not a spade or 5TJQ. (16/43 cards)
Pot will be $1100 with you both having $1750 behind on the river. Obv we want to be playing for stacks here. I'd raise to $575 or so (maybe even a touch more than that). This gives him ~2.9:1 and also makes the pot $1400, with us having $1600 behind, much easier to open jam, bet/call, or check/jam the river making him feel committed to the pot depending on his river tendencies, our line with previous strong hands/bluffs, and the river card.
Re the river: He shouldn't have a whole lot of flushes in his range, as I think the most of the flushes in his range are K
J
K
T
J
T
type hands. What other
hands is he 3betting you with pre flop? Maybe 7
8
type hand, but there isn't a whole lot of those out there. Esp since we have the A
blocker. There are certainly some sets in his range also. As well as two pair.
I think I'm inclined to bet/call on the river against a laggy agro. Maybe check jam. But given that we checked, I'd certainly check jam here.
