for a straight flush.
This is probably just a crap happens kind of hand, but . . .
I have to figure he's drawing, giving the flop action. And it's probably a good draw, because he was willing to bet it and then call a reasonable bet to chase it.
He checks the turn and then flat calls, but what the hell is that? A

Kx maybe, but it seems to me he has a flush here.
I don't really regret the call on the end. This hand just sucked.
