I agree with others that this should be folded preflop, checked on the flop, and folded on the turn. Im not completely against your call on the river, it looks like youre calling $20 to win a $125 pot. Id say you probably have a 1/3 chance of winning the low half, and combine that with the chance that the other guy has gone insane, and youve got pot odds to make the call.

Also, you cant say that you realize that someone has the ace high flush, and then say you have an openended straight flush draw.
