20/40 Live HU with Fish

[vmacosta]

The game is 4-handed with one tricky/aggro, one tight/abc and a fish. I'm stuck about a rack but fish refuses to leave with chips so I'm staying. Fish calls on button (his stats would be something like 80/1/1). I complete in SB with:

Tight/ABC BB checks
Flop is:
T [img]/images/graemlins/diamond.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img] 4 [img]/images/graemlins/club.gif[/img]
I bet, BB folds, fish raises, I 3-bet, fish 4-bets, I 5-bet, fish 6-bets, I call.
Turn is:

I check/call
River is:

I check/call.
