I was recently in a ten-handed 1/2 NLHE cash game. The table had a decent mix of tight and loose players, but nobody completely crazy. Generally, pre-flop raise to 25 was enough to limit the field to one or two callers, and one of them would just be fishing for a royal flush jackpot. We hadn't seen any pre-flop bets over 30 since the table started (4-5 hours).
I had been playing rock-tight all day, and I'm pretty sure everyone knew it. Before the hand in question, I hadn't played a single hand for nearly an hour other than a few small pre-flop calls that all missed. Then, I was in middle position, had one limper in front, and looked down at K⋄K♥. I thought for about half a second before popping to 40. One guy in late position ("Late"), one of the blinds ("Blind") and the original limper ("Limper") all called, all thinking for about as long as I had. This threw me for a loop, because a raise to 40 alone was unheard of, let alone such a raise getting three callers.
I'd describe everyone in the hand as tight-aggressive (but looser than me), and we all had roughly 300 chips behind except Limper, who had recently won a big pot with a big river bet and had closer to 600.
Flop came J♠8♥3♣. Blind and Limper both checked. I bet 80. Late and Blind called quickly. Limper thought for a second and raised to 160. I hesitated for a while, but ended up calling; so did Late. Blind frowned and mucked.
Turn was 6⋄. Limper bet 120. I'm pretty sure I made the right decision on this, but I'm still kinda salty, so I'd like to see what you guys think I should have done: folded, called or raised.
