0- to hit (nt)
Using SCORE comparisons, KO preferred matches up with HiLo I18+Fab4 in just about every playing condition, even without a true count conversion. Splitting 10's is not in KO preferred, so if you don't do that, it will almost always outperform HiLo.
... and it's a lot easier.
PS: The ReKO version of KO is even easier and is about 99% effective as KO.
With an unbalanced count like the KO, when your running count is at the pivot of +4 the information about the remaining deck content is very reliable. Therefore you can make your important betting and playing decisions at or near this running count. If you are further away from the pivot, your information is less reliable(e.g. at the 12 vs. 4 or the 13 vs. 2 index for 6 or 8 decks that you are looking at). If you are relatively new to blackjack, you should just follow the KO Preferred Strategy only.
I hit a 12v4 at 0 or lower and a 13v2 at -1 or lower. The problem this will be for you is I use a Hi-Lo count. I'm sure there is some conversion tables out there somewhere. Maybe try BA3, boring to read but is a great reference for EVERYTHING.
