Playing in a home game (1/1 with non-mandatory straddle that's on basically every hand), 8 people at the table, I know 3 of them well, the others maybe I've seen once or twice. It's around 11pm, the game started at 7, things have been relatively quiet except for the one real action player getting stacked a couple of times, once by me.

V: Young kid, around 21, playing pretty snug, sitting on around 190 to start the hand. It's my first time playing with him. Never limps, always opens for a raise of ~4x, has folded several times to 3!

H: Should have good image to V, as tonight I've only shown down winners, all my bluffs (c-bets) have got through. Thanks to an early double-up through another player, I've been able to leverage a biggish stack and chip up to 480 before the start of this hand.

V in MP raises to 8, folds to hero who looks down at AQ.

Normally I'd raise this in position, but I think I'm ahead of V's range considering he's raise/folded preflop several times already. I don't expect anyone to my left to raise, so I just call.

Everyone else folds.

(pot 20) Flop: 46J

V bets 10, H calls. We've got naked A plus two overs and BDFD. Is this the time for a raise?

(pot 40) Turn: 10

V bets 15, H raises to 40. I'm thinking V's small sizing indicates uncertainty. Maybe he's got TP, maybe AK, I doubt he's got an overpair because I'd expect a bigger bet here unless he's afraid of the flopped flush. I've picked up more outs, so I figure now's the time to put in a raise, but I suspect I went too small, 65-75 would be better.

Now V surprises me by re-raising to 90. He's got just 82 left behind so he's set up for a river shove.

Flat? Shove? (I lean towards shoving).

fold, villain clearly has a flush
