Thank you! Sounds like learning the Hi-lo is a decent choice for me.

The effect of removing an ace is much higher than in regular blackjack. So, the counts with the highest betting correlation tend to put more emphasis on the ace.


That said, there are a lot more relevant indexes for Spanish 21, so that a count with a strong playing efficiency can compete with a count with a stronger betting efficiency. Counting the ace really heavy for betting tends to mess up your playing decisions. So, Walker's Hi Lo unbalanced is about as good as the Secret Monkey count (Hi Lo, except the ace is -2) in a lot of scenarios.

All of that said, Halves should still get the money on Spanish 21. And if you don't want to use a different count to not mess up your main count, you can get Norm's software and run the indexes for it.
