Disagree 100% - bb should have a check raise range on this board bc it doesnt hit CO that hard. And QT is the absolute best semibluff to include because it has decent equity against the CO continue range, it blocks a lot of the CO bet/call range ( T9, JT, QJ) .Slam dunk check-raise.
I will give you that just because a player SHOULD xr doesn’t mean a player WOULD xr, and overly tight-passive players show up with that hand sometimes, but villain is just not giving off that vibe and he hasn’t shown down any hand to warrant that range adjustment
