UTG has seemed solid and aware, but also raises at least a somewhat wide range (J9o in late position) and comes off as slightly LAggy. My own table image was most likely similar to that. I hadn't shown down any crazy bluffs but I'd been raising a wider range on a pretty regular basis, and winning a lot of pots without showdown. I had not called many raises from others and this was my first float (semi-float, since I had a draw - can we officially start using that phrase, like "semibluff"?) against anyone.

Timing tells: villain was quick to raise and c-bet, pretty slow to call the turn and check the river.
