re: Poker & $25 NLHE 6-max: JJ, strange villian line.
Pre-flop is fine. C/c or bet/fold the river depend on his 3-betting %. I think you can assume if he has somewhat reg stats that you're not going to have mid pairs, so his range really shifts into Tx hands he wanted to pot control into, and weak Qx hands. You'd also have to assume he bets the flop with most of his bluffs and big draws. So really it depends on your 30 hand sample in terms of what kind of player he likely is. I don't think C/c is horrible on the river, but we can make better decisions with slightly more info.
