It was in the teaser & was only on screen for about two and a half minutes ... I was hoping for the lower parts of the pyramid to disappear, with the graphics reflecting your comments ... so you have (9J)9 v K v Q v 6 v 2 written on the bottom section of the pyramid ... and it disappears, because you're lopping it from your Stud8 game! Or maybe I'm just expecting too much! 
Yeah I suck at computer graphics, I'm really a noob but feel I'm holding my own enough with the presentation format so far.
OK, how about a more specific general statement ... folding marginal high hands (eg: split 8s-Qs) on 3rd when in early position with overcards and/or dead cards behind.
So are you saying there are all high cards to act, no lows? Well, its a Stud High hand to begin with, play accordingly.
What about when you have an 'island hand' ... say Ks v 7 low door cards (2-8 & no spades) ...
a) Is this a good steal spot, regardless of your hole cards?
I stated in Episode 1 that there is no extended-steal/island hands in Stud Hi/Low. Two many low hand opportunities, stealing has to be reserved for late position only.
b) If you are in a game with lots of callers, what would be the bottom of your range for raising with the Ks door (obviously you're raising split kings, big pocket pairs, etc), but do you raise (QJ)K here with a 2-suit? Rainbow?
No raising KJQ here, I actually talk about that here: http://www.deucescracked.com/videos/9611-Episode-Two?seek=2001
Depending what is live and dead, what position you are, and who and what are left to act, you could add in non-paired LsLs-Ks, where L=A-8.
c) If you are playing against players who tend to play their own hand a lot more than considering their opponents' boards (mainly thinking of playing live & noticing people who never look around at their opponents' boards), at what point (if any) do you slow down with a hand like (TT)Ks when your hand does not improve on later streets & your opponent(s) have somewhat scary boards (say they catch offsuit low card on 4th, high card same suit as door card on 5th, etc ... or go low, low but not connected or suited like 285r)?
HU vs a low, you will mostly be checking and calling vs non-scooping low boards. I will address this in the next classroom episode in this series.
Another situation I had in a live tournament ... opponent had raised with a 9 door & I re-raised with an A door ... he called & check-raised 4th when he caught a high card & I caught a low card & we capped betting. He caught an A on 5th & we again capped betting & he was all-in by 6th ... we both started rolled up (cooler I know) ... given that he was against an A door & he has an obviously high-only hand, is there any way for him not to go broke on the hand? Does the fact that he catches the case A on 5th mean he has to go broke here, as it is far more likely that I have split aces or four low cards rather than rolled up aces?
It makes no sense at all for him to get it in on 5th if you were showing a possible scooping low-board, esp after he catches the case Ace.
Also, given that you've really only started to get into high only hands ... and this is already episode 2 of 8 (for the season) ... should we be expecting the year to finish off with The Situation (part 6) ... when you finally get around to dealing with playing an ace door. 
Not that its a bad thing ... love the series so far & appreciate the detail required ... just the whole multiple board, split pot thing make it (seemingly at least) so much more complicated than holdem!
I'm pretty sure there is no way I can keep this series to eight episodes. It may be running for a long time, especially now that I'm entertaining adding live-play videos to supplement the theory videos.
