[Lister27]

The villian was 38/5.5/0.6, seemed fairly passive through out the session.

Was my fold correct, should I have bet the turn as well as the flop?

If you had Ax would you lead this flop?

Probably, but only because I almost always continution bet against one opponent. If I had Ax ckecking might look suspect so I'd just bet out as usual /images/graemlins/grin.gif.

I suppose checking would have been better with my JJ to make my opponent think I had Ax. Thanks for the reply.
