ENHC 11 vs dealer 10

With ENHC, is it advised not to double down with 11 vs dealer 10? Not even with high count (Hi-Lo or Knock-Out)?

Could someone clarify this? Thanks.

The index is +3,but listen what happened to me lately:
In a very high count I played two spots of 200 Euros and on both I got eleven against the dealers 10. I received a picture on both doubles but of course the dealer got the ace and instead of winning 800 Euros it went all down the drain.

You did the right thing.

So following this hand, it is obvious that with ENHC, we don't double 10 vs dealer 10, no matter how high the count is.

This was just for illustration what might happen with ENHC.
More often in this situation I get the ace and the dealer gets the ten!

I will have a look at PBJ.
Anyway at +4 it will be pos ev.But because of the huge variance associated with doubling down 11v10 in ENHC it might be better just hitting unless count goes sky high.Depends on your tolerance of variance is suppose.
Anyone know the risk Averse index?

...and my own CA-program confirms this figure.
I don't think variance for this play is so much higher with ENHC because a dealer blackjack with a ten up happens only in 8% of the cases.
Personally, I don't bother about risk averse indices because for anti-heat reasons I bet anyway less than my bankroll would allow.

Woah! Deja vu.

My copy has +4 too. I presume this particular index changed in one of the recent printings of PBJ. We all know that a difference of 1 won't matter anyway. Personally, I don't use this index at all in ENHC games.

I can understand people who don't want to split tens because they want to avoid heat, but not doubling 11 v 10 cannot be justified that way.
On the contrary, somebody who doubles 11 v 10 under ENHC has good chances to be labled as a gambler.
You ought to know that by not doubling at TC+10 you give away roughly 5% of EV which in a 200Euro bet represents 10Euro.
Why wouldn't you use an information you dispose of?

I use risk averse indices in the range of -2 (floored) to +6. The RA index for this particular play turned out to be above +6. That's all.
