JJ - get it in on the flop?

[crossroader]

With no reads i think u have to fold here. Assuming he doesnt have a wide rr range pf then good chance ur either beat here or he is a favorite to draw out, ran some numbers..if hes got either AK or AQ with a spade hes about 56% favorite, if hes got either AA, KK or QQ w/a spade ur toast (hes around 90% favorite) even if hes got AA, KK or QQ w/o a spade hes still about 56% favorite ofcourse he could b reraising with a much wider range but like u said hes unkown so i would give him credit for something. another thing, why not lead the flop to c where u are? may have been able to get to a relatively cheap showdown against qq, ak, aq, etc depending on turn & river. just my thought
