Laydown 1010?

[bnorthro]

Button is nearly all-in, so I'm not worried about his raise. SB's call of 3 cold was pretty suspicous. This is on my first orbit, so I don't have my stats up yet. Treat SB as an unknown (turns out he's 57%/31%/3.4 over about 70 hands).

Treating him as an unkown though, what's your turn move?

SB bets, Hero.....

I guess if I'm calling the flop raise, I don't believe he has an A. But then again, he called 3 cold from SB, check/raised the flop and led the turn. So he likes his hand, I guess an overpair is possible (though not likely) or 99, or some random A.

Against an unkown, what's your move? Obviously, knowing his stats I'm seeing a showdown almost regardless of the turn or river.

Thanks.
Also, anyone know of a converter for the PR network? I hate typing out these hands...
