Hi all,

While thinking about blackjack for a while (and while walking down the aisle of the casino floor), I found a terrific 3-play 9/6 Jacks or Better setup. And instead of my current, super-high-variance option, I chose to play at these machines. A question if I may.

At least two (WoO and jazbo) sites mention the following formula for the variance of a multiplay:

variance = vardeal + N * vardraw

That's 17.5 + 2N for the arrangement above. Does this mean that playing three hands is like playing three single hands of some hypothetical game with a variance of 17.5 + 6 = 23.5? Thanks!
