I think you played this fine. If he does have a lower flush that would explain his bet on the turn, rather then going for the checkraise. I think he's more likely to have A [img]/images/graemlins/spade.gif[/img] Jx as previously mentioned. I think calling down is correct since you lose 2 BB either way, but if you're wrong and raise him on the turn, you lose 2 more BB if you call it down and lose. You'd have to have a good read on the guy to raise him on the turn IMO.
