77 vs. SB

[thejameser]

5 handed. I am at work and don't have stats on the SB but I remember he was one of the more "reasonable" players at the table, but still to loose preflop.

Folded to me on button with 77, I raise SB calls and to the flop:

Jd 8h 9s

SB bets, I raise, it calls.

Turn: 7s

check, I bet it calls.

River: some K(not spade).

check, I bet, it raises, I.....(do I need to even ask?)
