I’m lying? Every computer situation I’ve seen has come to the same conclusion, so we must all be lying. It’s a secret conspiracy by the casinos. They don’t want you to know the true secrets to winning and instead get everyone to print bad strategy tables.
I’ve attached a screenshot of my sim results (sorry for the small size, 100KB attachment limit). The simulator is set to play with optimal strategy except for one situation — it splits a pair of 10s against a 6. Note that the expected gain of a pair of 10s against a 6 is listed in the screenshot as 0.45 . 0.45 is a lower expected gain than what is listed for a pair of 10s against a 2-5 and 7-9 because the sim isn’t following a foolish strategy for those hands.
If you don’t want to take my word for it, again check wizard of odds sim data… http://wizardofodds.com/blackjack/appendix1.html . He says 0.47 vs 0.70… roughly the same values as my results. Or check some of the dozens of other available sims, some of which are listed at http://www.bjmath.com/bjmath/ev/ev.htm (lists 0.43 vs 0.68 for standard RTG rules) . All say you should stand and not split.
