It’s an honor to now have Mason Malmuth on this Forum

I read his “Blackjack Essays” many years ago when I had
10% of the knowledge I have today about the game of blackjack.

On page 79 of Blackjack Essays, there’s a section: Doubling Down on Aces
I didn’t side count 789s back then but now that I do, I occasionally hit my AA with a surplus of 789s. Doubling down with AA, though, I never did.

Mr. Malmuth did not recommend the Aces DD but said on page 81 that in “rare situations”, it may be worthwhile to do so.

So today, I found at KCs’ BJStrat some scenarios where Doubling Down with AA is indeed the best play but detecting those rare conditions is possible only with a multiparameter count.

I never forgot Mr. Malmuth’ words of wisdom on page 82.

1) “The smart gambler is always winning to examine new ideas”
2) “The serious blackjack player should be interested in more sophisticated counts, multiparameter counts, key card concepts..”
3) “…be willing to examine a seemingly foolish scheme”

Anyone doubling down on Aces?
