re: Poker & $10 NLHE 6-max: All-in Pre or all-in on the flop
Honestly,math and HUD's aside, if the BTN is a known calling station then why are you only raising 4xBB, yet considering shoving with AQ? Why would you ever consider shoving with AQ or even Ak Preflop in the first place, especially in a cash game at these stakes?
Considering that you knew nothing about your opponent, the BB, and it's likely that he's trying to intimidate you, calling his re-raise with A,Q wasn't a bad idea in my book, but for the love of god you need to see a flop with a hand like that or even AK. This is not a tournament, and even then a flop is preferred. If it were just you two, in this case, putting him all in like that after you hit your pair wasn't a bad move IMO.
Since it worked out that way, and you hit your top pair - top kicker against a calling station, and in all likelihood a bully (with either a bluff, maybe low Pair, Ax-Kx, QJ??) following up with a standard continuation bet, I probably would've re-raised as well, but it would've been larger [3xbet] to take the pot from the BTN right there. I'm definitely not calling, so its either raise or fold postflop. Since I'm confident that I have the BB beat with my TPTK, then its gotta be a 3x Raise on the flop so that the BTN doesn't draw out on me. If you call, your just asking for him to raise because that'd be a very weak play in that situation and being the type of player he is he just might raise it and now you really have a decision to make. That's passive/weak poker for you, so only call in those situations if you flopped your set and there's no flush draw out there.
If the calling station calls, then I'd say you need to slow down. If he/she hits their flush or 2 middle pair on the turn, well...lol that's online poker for you. At this point check or fold if the pot gets any larger. You should probably realize your TPTK is no good and chunk it. I've learned never to chase top pair, even against a calling station, most of my loses came from that. Every now and then I'd win a huge pot with TP, but my losses far outweighed my winnings.
Weather I'm wrong or not about Postflop play (I'm either raisin' or foldin' no matter WHAT), I know you shouldn't be shoving Preflop with AQ ever - not at these levels or calling. Don't even think about it. Hell, it might be better to fold all together and stop playing for a few hours if the thought crosses your mind.
It sounds to me like this calling station, the BTN, was actually putting you on tilt. If he wants to donate chips, perfect. Your there to receive donations from players like him anyway, but you need to keep your wits about you to do it.
