3 to a straigth flush wheel including the ace, it doesn't get much better then that in stud hi-lo
Raise 3rd. after raising 3d I would probadly conitnue the bet on 4th since the 4 is a big scarecard for hi hands and everyone hit crap. Then I bet-call 5th, and obvoulsy raise every posibile time on 6th and bet-call river only if seat 4 raises ( if 4 calls and the other raises you gotta raise to get value out of a worse low, if he raises however he vould have you beat with a 64 or weel).
