"IF the dealer has a BJ (he doen't check for it though hole card) all hands are lost except the players' blackjacks."

That's what I thought too.

It's important to have this clear so that there's no misunderstanding in any report: Whether the dealer gets or not his hole card right after all players are dealt their 2nd card is irrelevant. Whether he checks under his hole card or not is also irrelevant (but why should he?). If, in the end, he collects all bets on doubles & splits from the players when he has a natural, this is a standard European No Hole game.

I'm sure if any European Hole game surfaces anywhere, we'll know pretty much instantly...
