This is about an hour long into a HU match, and the gameflow is basically like he's been running me over a bit over the last 5-10mins.


He's opening like 90% btns, calling bb like 7%. 3betting 32%...
I'm playing pretty taggy. Like 70-80 btns, 12% 3b. I've been doing a lot more 4betting while he's been calling 3bets pre and generally not laying down nor fighting for every pot.
I believe he's up on me, maybe 60-80bb at this point. Again my image is pretty taggy, I shouldn't look tilted or insane or anything. In fact I feel I've folded to way too many cbets (his freq is like 90%).

My question is basically, what are his turn betting/checking ranges, given the following:

-We both know/know each other know that: 1) He's 3betting a fucking ton; 2) I'm gonna float this board a lot. 3) The turn is a good barrel card for a lot of his air. 4) Bet-check-bet lines are viewed as strong.

The last one is questionable, but given how he's played a few hands prior, I felt it was a reasonable assumption.

Remember to consider also that stacks work out ok for a turn c/r.
