History: A few orbits earlier I 3bet his button open with AQo and checked a paired flop, checked 2 pair on the board on turn and check/called his river PSB, he showed A4s and we split.
Effective stacks $310, Button opens to $7, I 3bet
[Ac] to $23, Button Calls.
Flop:
[9d][8d] I check, Button bets $40, I call.
Turn:
: I check, Button bets $80, I have $250 behind, my move?
