My next session was quite brutal. I played well for the most part, but ran terribly. I did play one hand very poorly, and it stuck out in my mind. I can't grab the HH, but it basically went like this:

I get JJ in the BB. 18/16/2 in MP raises, 60/5/1 on the button calls, and I call because I hate 3-betting out of position. Questionable?

Flop comes Txx rainbow. If it was just me and the fish I'd value bet this all day, but because of MP I decide to c/c. I figure that the only hand he'll likely call with that I'm beating is AT, whereas he's very likely to c-bet AJ+ and underpairs if checked to. MP bets half pot, the fish folds, and I call.

Turn is another blank. Since villain probably bets pretty much his entire range on the flop, I still have no idea where I'm at. I know as much as I did last street, so I decide to c/c for the same reason as before. Villain bets half pot again and I call.

River is another undercard, but completes a flush. This doesn't concern me too much, because that's a very small part of his range. However, I'm still totally lost. Betting doesn't make much more sense than it did on the last 2 streets, except for the fact that the flush got there. Even so, it seems ill advised because he's probably never folding any hands that beat me. And it's slightly less likely now that he calls with AT. I check, and he bets half pot, not leaving much behind. I don't think it's very likely that he triple barreled with something like AK. If he was value betting every street, most of his range is beating me, except AT. I fold.

Now that I've written it all out, it doesn't seem like I played it that badly in hindsight. At the time I felt like I played it pretty poorly, but maybe this is just an example of why playing OOP sucks. Or maybe b/f is a better line on the flop or turn, but it doesn't make a whole lot of sense right now.
