JJ in BB

[NNH]

$10 NL 6-max

Is there a mircro-limits forum? Anyway, relevant stacks are...

Hero (BB) - $21
SB (just joined the table, seems ABC) - $11
MP (huge fish, will call down on every street w/ bottom pair no matter what's on board) - $6

Everyone limps to SB who makes it .30, I raise to $1 knowing that MP will call everytime. He calls, SB calls.

Flop is 99A - SB checks, I bet out $1.25 into $3.30 pot. MP folds, SB thinks for a bit and calls.

Turn is 9 - SB checks, I check

River is A - SB bets out $3.50 into $5.80 pot.

I really hate my play on every street here. Advice?

Thanks.
