This might seem trivial, and I'll probably be told to shut up and get my money in.
Game: Live .50/£1 getting quite late and the table is loosening up a little.
History: I've been quite active in position. I think villain has only seen me show one hand and that's when I raised AQ pre and took it down but flipped my cards whilst mucking them.
Villain: Haven't seen him play a hand yet, but only have a 50~ hand sample so we're pretty much in the dark here.
Hand:
Two limpers to me in the cutoff, I make it £6 with

. Villain is in the big blind and calls. Limpers fold.
Flop (£14.50)

. He checks, I bet £9, he raises to £18 pretty quickly with £45 back. I call.
Turn (£50.50)

. He bets £20.
It obviously can't be terrible getting my money in with three kings here, just wondering how often you think we're good here versus a perceived nit's obvious value line.
