Bellagio $30/$60, I 4-bet preflop, then shut down.

[Fianchetto]

Tight player posts in the CO, folded to him and he checks his option. I raise on the button with AKo, SB 3-bets, CO folds, I 4-bet, SB calls.

SB is a tight aggressive thinking player who I have played a lot of hours with. My read is that he knows I do not need a big hand to raise in my position, so he has likely loosened up his normally tight 3-betting standards from the blind a little (i.e. 88+, AJo+), but he will respect a 4-bet from me.

Flop: 8 9 Q rainbow

check, check.

He had chips in his hand and appeared prepared to continue, probably checkraising me.

Turn: 4

check, check.

After I check, he says something like "...you rascal..."

River: 7

He bets, I fold.

I felt pretty good about it afterward. Comments?
