According to the Wizard of odds, the Charlie rule (in this case the 7 card Charlie) modifies the basic strategy, but there appears to be a contradiction on his site. Look at the basic strategy for Playtech Blackjack surrender:

Playtech Blackjack surrender does have the 7 card Charlie rule
BUT
In the following Charlie strategy
http://wizardofodds.com/blackjack/im...harlie-hsd.gif (6 cards double after split) (he does mention 7 cards would be the same)
the Wizard has us not splitting 33 vs 2
AND FURTHER
http://wizardofodds.com/blackjack/im...harlie-hsd.gif
The wizard has us hitting (instead of doubling) A2 and A3 vs 5 or 6, A4 vs 4 or 5, A5 vs 4)

Which is correct?
