Can’t quite get the hang of card counting? Alan Krigman has come up with some interesting numbers when calculating how effective it is to count only ten-value cards and aces compared to the advantage gained by playing perfect strategy.
Bearing in mind you’d be neglecting all other cards dealt, it’s surprisingly effective. When a multi-deck shoe is down by half while less than half of the aces have been played, the advantage tips your way pretty quickly. Fewer than half of the tens alone will not result in any significant advantage, but a combination of fewer than half of all tens and fewer than half of all aces indicates a significant advantage. Krigman calculates the odds for an eight-deck shoe.
