REKO-F Double Deck H17 DAS Question for one silly index

**Paul21** · 01-13-2017, 07:36 AM

I am heading to Vegas soon to primarily play the subject game and a review of the Modern Blackjack REKO-F indices for DD-H17-DAD has me slightly puzzled when compared to basic strategy. Everything in REKO-F is logical except that the matrix has no entry for splitting 6,6 versus dealer 7 when BS calls for that play. I fully realize the value of this index is absolutely meaningless in practical ($) terms, but I'd like to know if I'm missing something here. Is it because the RA play is to always hit versus split?

For REKO there is no strategy deviation for splitting 6,6 versus 7. You just play basic strategy. I try to find an index for that play using CVDATA but the index generator came up with no deviations.

Your answer makes sense to me...but basic strategy says to split, and the index table says do not split under any condition. Hence my question.

Just a guess. The index never converged so the RA play was the best. There are sims running for analyzing a new game I am going to attack. The playing sims are starting to converge but a lot of the indices are slow to converge and some will likely never converge. They bounce back and forth between the 2 decisions as the TC changes. Either no index is ever converged upon and/or the correlation to the play is so poor that the count being used isn't worthy of being a barometer for the decision. Either way the RA play becomes the preferred option for the grey area where the correct play as viewed by the count is not converging for a range of TC. If the decision is always the same except for the grey area only one play is indicated but you can use the RA play for the grey area if the decision made otherwise is a double or split.

For a Double Deck game when Double after split is allowed it does said to split 6,6 vs 7. If the game does not allow Double After Split you don't split 6,6 vs 7. Attached is the basic strategy for Double Deck, H17, DAS.

Bs blackjack engine and BJA3 both have 6,6 vs 7 as a BS split. It's the correct play with 2D-H17-DAS. The REKO-F index table in the 2nd edition of Modern Blackjack says do not split...I was correct the first time and I need to quit arguing with myself

This is a weird hand. With HiLo, it is a reverse index. The best play for REKO is split when there is a neutral count. When the count is either high or low, the best play is no split. Since you are betting more at a high count, CVIndex calls it a no split.

Wow! Norm you are the best. Fully understood. How many plays on the table are like that?? This has to be one of very few, if not the only one!!

The basic strategy in Casino Verite Blackjack for double deck games are kind of weird when you check out the "complete basic strategy" it is not the same as the traditional basic strategy. It is saying to hit 9 vs 2 when basic strategy for H17 said to double but of course if you are using an index deviation for that play it doesn't matter.

Yes, I agree. Thanks for your input...and you also Tthree. Sounds to me like your answer is in line with Norm.
