Have some decent history with a very solid but creative reg. We are playing 5/5 and are both 2000 deep. I havé kk on the button and thé reg makes it 25 to go. I reraise to 90 everybody folds and he makes a somewhat quick call. Flop is q67 rainbow. He checks and I Cbet 140 which he calls. Turn is a q and he bets out 260. What to do and if you call what to do on river? I do think he puts me on a premium hand and is thinking that I can make a lay down.
