Easy call Armen.

I used to play that game all the time, and against the type of player you describe, I wouldn't even hestitate on the call. Against a regular, say like Dave, you fold. If you can't call (let alone raise the turn which you made the mistake of not doing) you're not bankrolled deep enough to play that game.

I'm guessing his range at AA, KK, (low likelyhood) QQ, JJ, AT, T9, missed big flush draw (most likely), or TT, 55, 6d4d (low likelyhood because it makes no sense to push the river if he wants a call). My sense is that he's been trying to take the play away from you the whole hand and either A) doesn't want a call on the river, or B) made two pair on the river and wants you to call his overbet with AA or KK.
