Surrender 16 vs 10. The expected loss from playing is worse than losing half your bet.
Spanish 21 removes all 10-value cards (but keeps face cards), making it harder to hit 21. To compensate, player 21 always wins (even vs dealer 21), and there are bonuses for specific hand combinations. The strategy differs significantly from regular blackjack.
With optimal strategy, Spanish 21 has a house edge of about 0.4-0.8%, which is competitive with regular blackjack. Poor strategy can increase this significantly.
Yes, always split 8s in Spanish 21. This is one of the few rules that carries over from regular blackjack. Two hands starting at 8 give better expected value than playing a hard 16.
When allowed, surrender 15-16 vs dealer 9, 10, or Ace. In Spanish 21, giving up half your bet is often better than trying to improve weak hands against strong dealer cards.
