1/3 300 cap game at Coushatta. Game has been pretty loose/passive on the whole, lots of limped pots and raised pots with 3-5 callers. Villian is a middle aged white male who is playing tighter and more aggressively than the table. My instinct is that he's at least a decent player who doesn't do anything too goofy, although I haven't seen enough hands to know this for certain. In general, I expect him to at like a solid, predictable but somewhat unknown low-stakes player.
I haven't seen him, or anyone else on the table besides myself, make many major bluffs. I haven't had to show any significant bluffs, and my image is solidly winning.
Stacks - 350 Effective
PRE-FLOP - Villian limps UTG+1, several more limps, Hero completes SB with QcJd, BB checks.
FLOP - POT ~20 - QsJh6s. Hero leads for 15. BB folds. Villian raises to 50. Folds back to Hero.
This is a pretty standard spot, but I'm trying to figure out what the best general approach is in a situation ripe for a semi-bluff, but against a player that would semi-bluff with a pretty low frequency.
