Effect of Removal for Blackjack

[lij45o6]

Hey guys,

I have computed the effect of removal for a single card for a 4-deck game. Would you be willing to compare your results with mine?

Rules:

• 4 French Decks
• Dealer Hits Soft 17
• Double after Split
• Split up to four(4) times
• RS-Aces(4)
• 2 card Natural pays 3-2

Here is the EoR (single card removed out of four for each number) I calculated:

• 2: 0.10%
• 3: 0.12%
• 4: 0.16%
• 5: 0.19%
• 6: 0.12%
• 7: 0.06%
• 8:-0.01%
• 9:-0.05%
• T:-0.13%
• A:-0.14%

NOTE: T accounts for 10,J,Q, and K.

The house edge is -0.0495%.

Are these similar numbers you get?

I got similar EORs for the same rules on https://bjstrat.net/cgi-bin/cdca.cgi rounded to the nearest hundredth of a percent. However, the house edge I got was 0.4929% (since the player EV according to the combinatorial analyzer was -0.4929%), almost ten times your result.

This thread is a bit old, but it doesn't cost me anything to post the EoRs that I calculated several years ago. They are Total-Dependent:

  4D,H17,DOA,DAS,SPA3,SPL3

A  -0.1392
2   0.0983
3   0.1147
4   0.1520
5   0.1798
6   0.1196
7   0.0639
8  -0.0075
9  -0.0535
T  -0.1320
m  -0.4975

Sincerely,
