Expected values of any starting hand

[Phoebe]

Hello,

I found this :
http://wizardofodds.com/games/blackjack/appendix/9/

but in
http://wizardofodds.com/games/blackj.../euro-6ds17r4/
there are many -1.00000 that I don't understand.

What do you thing about ?

Best regards

Sorry, my english is poor.

The -1 and up are for doubling down on almost certain losing hands if doubled.

Philippe, you are looking at tables for different rules. One is for games usually found in the USA and the other is European No Hole Card. They are two completely different charts.

Why is this yellow?

Thanks,

"Losing hands", I understand.
But, for exemple, 3 vs 10,7
Of course, hitting (nor doubling) is not the best answer. But, -1.000000 is ever losing.
Different chart give -0.532472, more logical.
And without dealer's Ten or Ace ENHC don't mater.

Philippe, I see what you are saying. I ran that hand (3 v 10,7) through iCountNTrack's analyzer and got the same ev (-.5342) whether it was ENHC or not. I do not know why the Wizard has that. Hopefully someone else can tell you.

If you double and lose all the time it would be -2,00 not -1.00 because you lose twice the wager you would lose if you hit. So on a double expectation of -1.00 is halfway to the maximum of doubling a 20 with no aces in the deck left to be played.

That is strange.....very strange....the figures are EXACTLY -1.00000. I would assume this is either a placeholder the Wizard put in for hard hands you would never double (hard 12 to hard 20).

Your question is probably better aimed at the Wizard (or JB).

I didn't worry much about it because you would never double the hands in question. But the point of the chart is comparing EVs for different play. It must be expressed in original bet EV to be a fair comparison. -1.00 is as bad as any non-doubled hand would be so that -1.0 serves the purpose for comparison for making te correct decision just fine.

[Phoebe]

Rollingstoned is right.
I have put the question in forum Wizard of Vegas and will back whith an answer (may be :-) )

Tthree, -1 is OK for making correct decision but
- others charts are fine.
- It's nice to know how bad is the hand.

[Phoebe]

Simply a mistake.

Best answer from forum Wizard of Vegas :
"I emailed Wizard about this a while ago. Looks like he only changed one of the tables. euro-8dh17r4 uses: N/V = Not a viable play."
Thank you all.
