The boat that I play at has 6deck, DAS, H17, no RSA. When I have 11 vs an ACE, I've been hitting. In December's issue of Casino Player Henry Tamburin says to double 11 vs Ace in a shoe game where a dealer hits a soft 17. I then went to blackjackinfo.com and yes indeed I've been playing that wrong.
I'm not quite sure why I'm posting this but I think its to get feedback on how others play that hand.
