SB showed 9 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img] and took it down.

I called that turn bet while doing my "pair the board" chant, but after seeing his hand I'm wondering if he would have laid it down to a raise.

I have to call the river bet here, right? Sometimes I'm not sure exactly how "big" a "big" pot is.
