I didn't see any way to provide updates for the Current Blackjack News without joining the Green Chip Forums, so I guess I'll post my observations from my recent LV trip here:
Almost Everywhere - Blackjach Switch games everywhere I played no longer consider a "switched" 21 as a natural. Instead, it will now push a drawn dealer 21. The listed house edge in CBJN of 0.18% is no longer correct - it's more like 0.6%.
Encore - Every table I played at allowed surrender. The CBJN listed edge is too high.
Fitzgerald's - Spanish 21 allows double-double-down, lowering the house edge to around 0.4% from the listed 0.78%. This one is a bit annoying, since 1) it has been in error since at least 2007, and 2) the rule in question is POSTED right at the table. You don't have to play the game, or even talk to the dealer or pit boss, to establish the rules in play. I know Spanish 21 is not too popular and a dying game. Still, has someone really visited Fitgerald's every month for over 2 years and not noticed this error?
