2-2-5 NL. I flop quads against a HORRIBLE player.

[flytrap]

2-2-5 NL game at Greektown in Detroit. There is a HUGE fish in the game that usually goes through about $4000 in 2 hours. He raises to $25 preflop every hand. He has about $2000 to start this hand, I have him covered. He likes to bluff, and will sometimes pay off big bets with modest hands.

Fish is utg and raises to $25. I'm in the CO, and it folds to me. I make it $75 with 9 [img]/images/graemlins/spade.gif[/img]9 [img]/images/graemlins/club.gif[/img]. The BB goes all-in for his last $75.

Pot is about $230

Flop is T [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/heart.gif[/img]

Okay so obviously this is the flop I'm looking for [img]/images/graemlins/cool.gif[/img]

Fish bets $100. I call. Pot is now $430

Turn is T [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]

Fish bets $375. I call. Pot is now $1285.

River is a blank. The fish has about $1500 left.

He checks to me. How much do I bet?
