I found an error with the Basic Strategy Trainer found on this website. The error occurs when "Early Surrender" is used. When either Dealer or Player get a BlackJack, the play automatically ends. There is no opportunity to Surrender if the Dealer has a BlackJack. The Player should be able to select to Surrender before the Dealer checks his hole card. So essentially it is not early Surrender but late Surrender.
