re: Poker & $50 NLHE Full Ring: 77 B.B. Pre ??
Smooth call the flop, a re-raise would risk more cash. After the flop, I'd make another call to see where he's at on the turn. This probably turned out to be an interesting hand; many options available, anything could have worked. Hopefully he just has AK or KQ, and maybe he's trying to push you guys out after missing the flop. At best, he might have JJ or so. If so, that's unlucky. The only way to find out is by putting your money in the pot, whether you win or lose.
