Hand one, 1200 continuation bet, take it down. Take a free card on the turn from the loose passive player if he calls. Bet or raise if you made top pair or a straight, check or fold if you still have Ace high.

Hand two, check calling has given you precisely no idea where you are in the hand. I like leading out at the flop. Why call the flop and not the turn? Nothing has changed. I guess I grudgingly fold the turn the way it was played. You aren't finding out whether you're ahead or not without risking all your chips.

Hand three, fold preflop. I like the flop and the turn. If he doesn't have an Ace, he's not paying you off at all, but if he does, he'll probably pay another 800-1000 I guess. So raise to 1400 or so. Pretty read dependant. What's your table image?
