1 - I'm not betting the turn... you only beat a bluff or a fish right now (someone with a high or a 9).. ugly flop ugly turn.
2 - An 8x raise preflop with no action is front... this is read dependant.. you say the table was tight, well I'm just folding here unless the guy has been a maniac giving me good reason to think AQ is good.
3 - C'mon, you know this is a bad beat! You should have lost a stack here (results oriented) instead of losing $10.

Always buyin for full.
