Orson: Question to Zenfighter

[Orson]

In the thread below (about 5 card Charlie), you gave an answer to another guy who asked what is worth any 5 card automatic win for the player. My question , however, was, what is the extra BS advantage if player can receive a bonus equal to half of his bet. I assume it could be something like half of the above figure, but it is just a guess, since the connection most likely is not straight linear. Also, my game is ENHC, which means that it is possible to collect half a bet even against dealer's natural.

Any chance you can give that figure for me?

Thanks in advance,
Orson

For a Five?Card half win, playing perfect BS, and 6dks with standard ENHC rules,
I?ve got this:

BSE = 0.05% (0.02%)

For ENHC, 6dks, S17, DB9, DAS and RSA

BSE = -0.57%

Therefore your total gain, with this wonderful option is 0.62%, close to what your intuition has told you.
You?ll need only slightly modifications to Wong?s recommended BS, as usual, when dealing with enhc rules. That is, do not surrender your 5 card total of 21 vs. a dealer's ten, but beware of the dealer's ace. Needless to add that the European ace is a ?criminal?, and like all these ?gentlemen?, should be treated accordingly, that is to jail with him! Or in plain English, accept your 50 ? ( woh, my new laptop has euros!) when holding a 5 card 20 and/or 21 vs. an ace, for a 100 ? bet, naturally .

Btw, if you want my e-mail for whatever reason, feel free to ask me, I?ll be glad to have a new BJ friend like you.

Sincerely

Thank you for prompt response.

If I understood right, you compared standard European bencmark rules (-0.57) with the simulation results after 5 card half win was added (+0.05). The difference you got (0.62) should be the net value of the 5c charlie. But what means 0.02% in brackets?

Also, after re-reading your earlier post (response to Mister M) I am still confused with equation:

WR = .693 SE = .014

This has nothing to do with my case, but just make sure I can follow your logic: the only thing I think I understood here is .693, which is supposed to be the simulated off-the top edge. Maybe my question sounds stupid to you, but what is WR, SE and, after all, .014? Win rate? - if so, how it is measured?

Yes, just a little addendum - you almost correctly predicted the set of the rules for the game, with two little omissions: DOA and ES vs. everything, incl. Ace:-). And it is not played for euros (geographically, it is not even in Europe). I don't think you will go there to play anyway, but feel free to drop me a note to my hotmail address above - I also like getting new BJ friends.

Best regards,
Orson

I believe that WR is win rate of this rule in percent for a BS player while SE is standard error. Shark

The figures I?ve got for standard ENHC (not for your marvellous ones, with DOA and ES)

are a product of a quick simulation . Every simulation gives you an estimate of the true value,

which clusters around the SE ( Standard error) who tells you how far of the true value the

result you got by simulation can be. E.g. WR = 0.05% ( se = .02) means exactly

68.3% prob. that your true advantage is between [ 0.03 and 0.07]

95.45% prob. that it will be between [ 0.01 and 0.09 ]

99.73% prob. that the true advantage be somewhere between [ -0.01 and 0.11]

so as you clearly see, with the last one, you have cover 3 Standard Errors to both sides.

For practical purposes here inside will be your true advantage or disadvantage.

If your local rules allow DOA and ES, then congratulations.

Standard = -0.57
.......DOA = +0.091
.ES 10/A = +0.628

Total = 0.149 (without the 5 card bonus!)

I?m guessing now where you?re living. Someone told me the best rules of the World at the present time are in your nearby. Shall we all be envy here at DD ? :-)

Take care of your candy store.

Due to some optical trick I saw a sign of multiplication where it actually was just a space.
So WR = .693 x SE = .014 made me confused. Thank you for clarification.

But your quess about my residence is probably slightly wrong. In fact, the game in question is some 8000 km (more than 5000 miles) away from my home. So, it would be a slight exaggeration to call it "my local game".

Best regards,
