$1200 eff. My image same TAG grinder. V same and I think he's definitely
one of the better grinders. Played with each other many times before.
We have similar styles of play but V is more aggressive than me. We
generally see each other as tight player that we are at our core and
generally stay out of each other's way. But........

This guy was
now second to my right and he fancies stealing every button. I generally
fold. I 3-bet him sometimes with a widened value range but other than
that I've folded to him his steals this session. This session I 3-bet
him twice before and he folded. First time about 1.5hr ago and last time
5 mins ago.

Folds to V, V dutifully opens to $30. SB regfish
folds. I make it $100 with K9s. V is clearly displeased, asks how much
I'm playing.. and reluctantly calls.

Flop: T86r Pot ~ $200 I c-bet $100. V calls.
Turn and river check-check.

I
show my K-high, he shows Q6o................... What went wrong? Or
maybe nothing went wrong and I should just 3-bet him way more in the
future vs his 100% range? What are the implications for metagame as
we'll play a ton in the future?

P.S. Turn and river are not
provided but if you think barreling may be in order, just describe what
turns and rivers you would barrel.
