The SB in this hand was one of the worst players I've seen in a long time. On a previous hand I raised pre-flop, he called from the big blind and potted a rag flop, I raised all-in with two overcards and a flush draw and he insta-called with 23o for bottom pair which held up. He's since lost most of it back but has about $75 left (this is 1/2 and we're 4-handed).

I get dealt AA and make it $7 from the CO which I've been doing a lot, donkey min-raises to $12 which he's also been doing a lot, and a guy who just sat down with $200 cold-calls from the BB (I cover the table). I just call because I want to stack the donkey and don't want to blow him out of the pot. The flop is 2 9 T. I have the ace of clubs if that matters. Donkey leads for $20, BB calls, I make it $70, donkey calls all-in, BB shoves. What have I gotten myself into?
