I think the main idea of the 3bet on 3rd is to make life very uncomfortable for the K. Dan Zack is going to have to fold almost everything vs this action - in game he folded a 3 flush but I think split kings just need to fold as well (perhaps with an ace he can consider continuing). Getting a better hand to fold a real amount for just 1 extra small bet vs coldcalling is a massive win.

I do think the play also conveys a lot of strength and often induces our opponents to play more passively on later streets as well. We will be in position vs the A on later streets on most runouts so we have the option to take free cards as we see fit.

Thanks!

O8 - really situation dependent, in a game like this often inadvisable but anytime we have a strong chance of getting HU it's fine. Sidecards do matter a ton of course - AAT9r is very trashy, AAQJss not so bad

9:30 - I think just fold with a bad kicker, certainly rainbow. Vs a very tight 2bettor he can consider folding (AQ)Q but I rarely would, as I stated in other comment above he can get Dan Zack to fold split kings a ton by 3betting here and get HU vs a range that he should be doing just fine against given that he's blocking split aces.

33:10 - Good question here, I think it's close but think the occasional scenario that actually unfolded in hand makes just betting a little better. Even if we get one paired hand to fold and the other (Ben in this instance) catches good and raises us, we still have plenty of hope (see pic attached, used Keith's hand as dead cards and subbed one of Ben's holecards)
