Yes, I know, I just wanted you to realize that if you expect to come to the US and use your strategy, you will have to make some modifications. Playing all spots is a foreign thing--Britain, Europe, Australia, Central America, cruises, etc. In the US, you would indeed need big $$ to get such conditions. (With big enough $$, you can also get special rules, such as DAS and LS.)
"Here in VD I am allowed to say this: there is more to Blackjack than just Math."
Actually, you are allowed to say that anywhere. But in VD, as it is outside VD, you'd be wrong.
And, yes, we agree that third base can be a "power box," provided third base has next-card info (equivalently, some info regarding the non-random ordering of the remaining cards of the pack). Without any information, third base has no influence over anything. If the top card of the pack and the second card of the pack are randomly mixed, what difference does it make if the third base player can deliver the second card to the dealer, instead of the first?
