Vindication by Anthony Curtis’ Las Vegas Advisor adopts the 8/9 side count:”Specifically, high-value cards (8s, 9s, 10s, and especially aces benefit the player more than the dealer. Low-value cards (3s, 4s, 6s, and especially 5s) are better for the dealer. More high cards remaining to play increase the player’s chances of hitting a two-card 21, which pays a bonus (either 3to-2 or 6-to-5); conversely, more low cards help the dealer, who has to draw to 17, avoid busting with “stiff” hands (12-16).”!/x/status/1363841799979102208
