If the player has Ad-Tc + 6h-Td can you switch the tens to make a suited BJ in the left hand? What does 'switch again' mean? I thought there was only one decision point for switching. Does anyone know if there are any other 4 card player hands where it is correct to Switch and breakup a BJ? So far, I have not noticed any hands in which it is mathematically correct to break-up a Blackjack by Switching, except when the result is to create a suited blackjack. I am starting to evaluate the rule changes you list above, but I have some questions.

of 0.579%, which is surprisingly (perhaps luckily) close to the rigorously correct result that Wizard calculated and reported on the WOO site. Given standard BJ Switch rules, it calculates a H.E. It uses the table in the WOO Blackjack Switch Appendix 1 and evaluates and optimizes the Switch/NoSwitch decision for all the possible 4 card combinations that player can start with and for each of the dealer upcards. I have written a spreadsheet model of BJ Switch that is not 100% rigorous, but is pretty reasonable. If possible can you also tell me the chances of getting one (or more) of the hands below per game under the above rules:Įven though this is my first post/thread, I have been a long time reader of the 'sister site'/ Wizard of Odds and can usually work out what I need from the information provided there.Īll help will be greatly appreciated, thanks. I would also like to know if these variations can be added together or if the 'total is more or less than the sum of the parts', that is why I put 'rule variation 3,' in even though the Wizard of Odds site says it is worth about 0.4% to the player. All Switched Player Blackjacks wins against a 'Push 22' and a 'dealer 21'Ĥ.(a) When the right hand has a Blackjack you can't switchĤ (b) If you switch and turn the right hand into a Blackjack, then you can't switch againĤ (c) If the left hand is a regular blackjack, and the right hand is currently not a blackjack but can be turned into a Suited blackjack, then this is allowed, but the opposite is not (see '4 (a) and 4 (b)' above).ĥ. Game: 6-decks, hit soft17, dealer will peek for blackjack and all bets will lose except a player blackjack will push (see link below for further info about the standard rules for this game).Įdit, the link doesn't work, so just search 'wizard of odds blackjack switch' to find the site.įor the game above I was wondering what the reduction in house edge is for the following rule variations:ģ. There is a game of switch that possibly has a small player edge, see below:
