I highly doubt antoha1998 is recreational :)

I did sim on most on those hands too in the past (maybe month ago), because wasn't sure about the plays either. Results were pretty much similar at most (slightly different of course because of the ranges, but nothing crazy)
Last hand If you only allow small betting on the turn for OOP, it gets to bet more often (maybe 25% of the time), and still overall checking close to 60%

Like this video format.Keep going!

Nice video, Paul.

at 35:30, regarding calling with or without spade, you may be interested on this recent Sauce's comment in a pretty similar spot:

CO vs BB on 962r3, vs 2nd barrel (medium sizing),

"A6 is too strong of a made hand to fold regardless of suits. In this spot, having the As will increase the EV for turn OOP call because IP will bluff less frequently on spade rivers and when he does bluff spade rivers OOP will have a +EV continue. IP bluffs on non spade rivers will typically be randomized and occur slightly more frequently than if OOP did not have the As. Overall, the As vs not As effect might be +- 1bb in EV on turn once we cancel out these two effects, so it's often not essential to understand it unless we have a very close decision."

(end of quote)

In our hand, I would add the As doesn't block that many (extra) bluffs, because on BTN shoes Asx (offsuit) also blocks some backdoor FDs that are calling flop then folding turn, so these combos aren't really preferred for bluffing over others Ax (offsuit). I think other high spades usually block more bluffs than the A does, however PIO tends to mix its bluffs a lot, also flush draws, so I'd assume your thinking about bluffcatching spade being negative might work better in practice than it does in theory.

This is my favorite video format

Great video! Please do more of this format with more high stakes hands :)
