This is a weird hand but I think I probably call. The overbet all in really makes this seem like you are not up against a set. If he flops a set why overbet all in and risk losing you if you have AK/AQ. I haven't played micro limits in a long time but do people really smooth call with KK/AA preflop? I think there is a pretty good chance here to run into JJ-99, a flush draw or even A8. A better read on this guy would be helpful but I lean toward calling here.

Rhound is right as per usual.

i would call.

there are no straights. no flushes. 2 pair is practically impossible. and there is a flush draw.

so......call. favorite against a flush draw or 65, flipping with flush draw + overcard, ahead of JJ, TT, 99, 8-x. and you'll see some retarded no-pair hands from time to time.
