Is it just me or does this look like the old stack-a-donk situation with AA? I mean this looks to me like a classic situation where you shouldnt go broke with one pair in a once-raised pot. Furthermore, the villain is loose passive, meaning he isnt pushing his draws here. He's probably got a set! I fold here everytime.
Answer Q 15: raise to 250 (you have AKo on A95 rainbow flop)
I think calling is better here. I mean standard TAG power poker dictates a raise here, but by calling you can often figure out how good you are on the turn and/or trap weaker hands into putting more money in the pot than they should. You arent worried about getting sucked out on so much because the flop is so dry that the villain probably has very few outs against you if he is behind. So you dont need to protect your hand as much.
