re: Poker & $10 NLHE 6-max: Did I play QQ right here?
If the population tendency is 3-betting light in that spot a lot, something like 7-9%, then cold 4-betting/calling off is probably the better play. You are getting a ton of folds in this spot, and picking up 20bb in dead money pre is pretty nice. CO shouldn't be much of a concern, since they're usually opening around 20%. BTN is a nonexistent issue. 4-betting is high variance though, and running into the top of your opponent's range would suck.
I don't mind the flat to keep the SB's range wider, and by cold-calling, we are repping exactly what we have. I don't think people are going to try to bluff you off your hand when it's so face-up. If CO/BTN call, that's okay too. We will be way ahead of their range, further decreases the chances of us getting bluffed off our hand, and increases our set value.
Flop fold is totally standard. There's absolutely no reason to call or make a move here. Even if you thought the SB were making a move (which is very unlikely), you still have the BTN to act behind you. You don't even beat KK, and flush draws have a ton of equity against you. The BTN could have been passive with AK, have AQs/AQo, AJs, and sets. Folding QQ here is not weak.
