Too much or too little?

[jkamowitz]

This hand takes place sort of in a vacuum because it was my second hand at a table full of unknowns. The only tiny read I had was that during opponents first hand he raised preflop and bet the flop and bet/folded the turn on a Q235 three hearts board. That's all I have.

6 handed 20/40. I don't chop 6 handed and I announced this before the hand was dealt.

4 folds and I raise KK in the sb. BB says "chop?" I reply "I don't chop 6 handed" and he shrugs and 3-bets, I 4-bet, he asks the dealer "can I raise again?" the dealer nods "ok I call"

Flop: 553r I bet, he raises, I 3-bet, he 4-bets, I 5-bet, he 6-bets, I call.

Turn 2o I bet, he raises, I call.

River J I check call.

How would most people play this vs a complete unknown in this spot? This happened a while ago but I've always been curious.
