We're pretty early in the match and I was up a few buy ins. Villain was passive in 3bet pots at this point so I widened up my 3bet range to 20% and a C bet would usually win the pot. Given how he was reacting to 3bets I decided to go w/ a 5x and get the most value out of his mistakes.

What kind of range do you guys think he gets to the river w/ and how do you feel about the sizing and action I chose?

He was folding to C Bets a little more than 50% so I chose to lead into him in many different spots with both value and bluffs. In similar spots I had chosen to bet smaller w/ lots of value so I went w/ a half pot bet instead of my standard 2/3 pot bet. He was playing more cautiously when I chose this sizing.

When he just basically clicks it back I'm not putting him on a very strong range. Earlier in the match he had been calling 3Bets w/ bad suited K's & A's so I definitely felt hands like K7, K8, A8 were in his range and he would make a fishy raise planning to steal the pot on the turn if I checked w/ overs.

The 6 didn't change anything for us and he was floating a lot so I went w/ another half pot bet. After he raised the flop trying to (in my mind) fake aggression I though it'd be best to stick w/ the plan barrel like I was going for value. I had A8,A9, and overs in my range for sure and had only been called when I had it in previously spots. When he flats after raising the flop I'm convinced even more that he isn't very strong.

When the 8 rolls off i think I have to pull the trigger for a 3rd barrel here every time. I want to get paid off in this spot in the future and so he was calling when I barreled for value. Even if I got called here it would bode well for me later as I was barreling value a lot.

The 8 hits more of my range than his unless he has exactly a T because any combo draw would have been played more aggressively imo. I also felt like he would be folding his 2nd and 3rd pairs he called w/ and he had been wrong hero calling in the spot a lot already.

I based my sizing on how I'd play a value hand here and went a little larger than the 1st 2 streets. I didn't want him to sigh call because I bet half pot again. I started to go for an over bet all in of $2300 or so, but he was playing guessing games when I chose that path and he had seen me bluff a lot more in those spots.
