Answer is probably no, but what hand can I put him on other than a Q. A worse 7 perhaps? Do you fold this?

if it were me id raise the flop bet the turn and try to check behind on the river if i thought he had a queen.
As played you have to call the river i think

flop call sucks.

play your big hands faster, start raising the flop more (just read your AK top two hand as well). it seldom makes sense to slow play flopped trips on a paired board w/ a flush draw like that. you lose value to a lot of hands that may call a raise by just smooth calling (flush draws, another 7x, KQ, AQ, JQ, 88,99,1010,jj) and your hand falls behind any spade or Q so.

build the pot while you're ahead.

Yeah there's no need to play so slow on any street

Good call, I am experiencing a downswing right now. Maybe I am having a little problem with fancy play syndrom. Thanks!
