flop raise is fine, usually i give up if called...

wouldn't betting river have been much better than calling this, though obviously u were hoping for a check behind...

i think he may have a Q/midpair/A trying to get u off an A here, bluffing with the best hand kind of thing...

edit: actually, a Q is prolly not a likely holding given flop action, an A might be and he might be getting tricky with the turn check
