5/10-quite common annoying river situation

[invisibleleadsoup]

no reads on villain,he just sat down.

i've been playing quite agressively,firing quite a few second barrells and so on.

folded to me in the SB,i make it 35 with AA,BB calls,he has about 900.

flop 7 T K, two spades.

i bet 60 into 70,he calls.

turn is an A,i bet 150 into 190,he calls.

river is the 4 of spades,completing the flush draw.

so i've got about 500 in the pot,say 700 left to go in.

this is a really annoying situation,i've got top set,but then again if i push/bet the pot is he really going to call with less than QJ?

if i check,however,he checks behind with any hands that i beat,and pushes anything that beats me.

i mean i almost feel like check folding,since any hand he has with showdown value that i beat will check behind,and he can't be bluffing since all the draws have hit.

this feels horribly weak,so should i just bet and hope the times he calls with two pair outweight the times he has me crushed?

this might be really simple stuff,i'm a little rusty at the minute so i'm going to start posting more as i get back into the swing of things.
