Both of these hands are against the same opponent, who is a regular and very LAG. pt's auto-rating puts him as maniac in fact, but he does know what he's doing. During this session, at least up to the time of these hands, he seemed to have slowed down quite a bit and had largely been staying out of my way, although I had had a pretty sweet rush early on where I was betting like crazy (although pretty much always with a good hand of some sort). I've seen him have some big runs with this style, but he also loses a lot of single buy-ins in the process. Not sure whether he's a winning player in the long-run or not.

Hand 1: I limp UTG with KdKsJd2c. Folded around to LAG (I'll call him that because I really don't consider this guy a maniac) in SB, who makes it $6 to go. BB folds, and I call. I have around $400 in chips, and he's full-stacked.

Flop comes Js7c3c. He checks, and I bet pot ($13.30). He calls. Ok, he's got a piece of it, but I have position. I think I'm ahead at this point, as I'm quite certain that he would have bet out AA or any 2 pair. But I think he's also very capable of trapping with some kind of JJ (although I think he'd probably check-raise that, not completely sure).

Turn Qh. So, I still have my overpair with no straight or flush showing. Here, I check. I think this was a mistake, but I didn't want to build an enormous pot with this hand. I really wonder whether it wouldn't be a good habit in HU pots like this (at least raised ones) to bet the flop more like 2/3 pot (in this case $10 seems nice), so that I could also bet $25 or so (in a pot of $33) rather than close to $40 on the turn. And that of course with any hand that I want to bet, including monsters.

River another 7, and he bets $10 into the pot of $39 or so. Well, this is an "I want a call" bet, but I call it anyway. He turns over TT97 and spiked his trips on the river.

He played the hand actually pretty straightforward here, and the flop call, albeit marginal, certainly wasn't horrible. I think my biggest mistake was checking the turn, which really forces me to call on the river. If I've bet both flop and turn (whether pot or less), I don't see how he can possibly bet into me on the river without SOME hand that beats me. Against his actual hand, I also think I have quite a bit of fold equity--and am quite a bit ahead anyway.

Hand 2: Pretty much the same situation, except the former BB has left an open seat (maybe even next orbit after the preceding). Folded all the way around, LAG completes. More or less the same stack-sizes, and I have Jc8h6h2c in BB.

Flop comes Ah8c4d. So, I have middle pair with 2 runner-runner flush draws, possibly runner-runner straight, too. He checks, and I pot it for $3.80 (I'm obviously not talking about these kinds of pots with the 2/3 pot question). He calls.

Turn is Js. Well, no runner-runner flush for me, but I have 2 pair. He checks, and I pot ($11).

River is Qd. He checks, and I check. He turns over AKQ5 for a bigger 2 pair. So, he was ahead on the flop, behind on the turn, and ahead again on the river.

I think I played hand 2 fine, but hand 1 poorly.

Cool, thanks!

To your question: Yes, sometimes, but not often--and actually I usually regret it every time I do it.

The way I really like it HU is betting even the vaguest piece of the flop consistently with the biggest monster and checking in position basically means I missed completely and need to fold (exception: hands like no pair with gutshot get checked as would most hands with or without pair where I can make a big runner-runner flush). Basically, with position I'm checking (the flop) if I have absolutely nothing or else a very minimal current hand where I'd still really regret not seeing the turn.

On the turn, I don't mind checking behind if I have almost a lock on the hand--like set with flush draw or such--AND a very aggro opponent who's almost certainly going to bet the river after that.
