Live NL 5-5 Hand

[coltrane]

7-handed Live NL 5-5 Game

I am shortstacked ($300) and the whole table has me covered...I'd say my table image is fairly tight...

one limper, I limp with 87o, button limps, blinds check....

Flop comes 764 (two hearts)

SB bets out $35 (he seems like a pretty tricky player and has bet on raggedy flops and scary flops before - many times with nothing)....BB and MP fold, I feel there's a very good chance I'm ahead at this point - I call, button folds....

Turn comes 2 of spades....

SB bets out $75....

what do you put him on and what is your move?......
