The BB is unknown the CO is a reg I know very well (7,5k hands).

He plays 23/19 with a 3bet of 7%. He plays pretty face up, and its often easy to narrow his range down.

His coldcalling range from the CO is 9% which should propably look like that, given that he only 3bets 2,2% from the CO:

QQ-55,AJs+,KJs+,QJs,JTs,AQo+,KQo and sometimes KK+

On the flop a x/fold is probably better, given that we are 3way, but as played Villain calls my bet. I am pretty shure, that he would not call here 66/55 ever, and would nearly always raise them.

Postflop stats:

- rasie cbet 12%

- F2 cbet f/t/r 48%/41%/80%

On the turn I decidet to barrel of, becasue I block the 87s combos and I would assume, that Villain is going to fold his KJs/KQ/AK combos on the river. On the one hand that does not rearly make sense, becasue Villain does not have 87s in his range at all, on the other hand I am pretty sure that I am always behind after his flopcall and he folds so much on the river.

What do you think?

How big would you bluff on the river?
