Saturday night was the first time I had seen a player double on a blackjack. The casino allowed it, and the player won!!
Does this happen often? Do certain counts warrant hitting or doubling on a blackjack? (Overall, this player did not seem to know what he was doing, and most of us were betting $5.).
I think Don S once posted how bad this is. I can't remember much on it, but don't do it.
Naturally, it depends on what the dealer's upcard is, but the best advantage possible, off the top, for doubling A,T is 67% vs. dealer's 6, in a 6-deck game. Compare that to the certain 150% from accepting the 3:2 payout, and you can see what a moronic play this is.
Of course, a very high positive count would produce a higher expectation, but the comparison isn't worth discussing.

Of course, it becomes more correct at less high counts if you split XX, are dealt an A, then double (ie you no longer get 150% payout). Just try to collect your chips before you're ushered out the door.
Agree with all who posted. Of course, the responses given were presuming that you did not know the value of the next card to be dealt. That would definitely be useful info in that situation.
Everybody has a read a sign that said "double on any 2 cards except a point count of 21". I don't get their repressive stance. Maybe it sours the prize of a natural.
Double 21 after a split is a glaring AP move. I've never done it but the ones that do, don't care about longevity.
that's situational. Splitting is different, it's not a natural. They offer insurance too and you can capitalize on that. I think they want to preserve the prize, it loses meaning, especially 6:5, then that would increase some doubling, not that you should be playing that type of game.
If I got 6/5 at DD and decent pen, that's when I would play it.
