This is a very big advantage for the player. Most every major casino in Las Vegas or Atlantic City will NOT allow one to do this. In fact, some casinos will only allow you to double on a hard 10 or 11.

2) You can re-split Aces / draw more than one card to an Ace

When you are fortunate enough to hold two Aces, you should always split these. However, many casinos only allow one card to be drawn to an Ace! Other casinos are a bit more liberal... they allow just one card to be drawn to an Ace unless that card is another Ace and then that too can be split. Yahoo! allows any number of re-splits and cards drawn. Very nice.

3) Any Ace - 10 is a Blackjack.

Many actual casinos only consider a "blackjack" an Ace and a 10 on the first two cards only... meaning if you have two aces and split them and receive a 10 on one, you simply have 21 points, not a blackjack, and would not get paid 3 to 2. Yahoo! however graciously treats any Ace - 10 combination as a blackjack and pays 3 to 2 (1.5 to 1) for this. This is true even if the dealer later ends up with 21 points!

4) You can double after splitting.

Once again, many actual casinos, once a pair is split, will not allow you to double if you so wish. Example: You hold 8, 8 and split these and receive a 3 on the first 8. You now have 11 points and here at Yahoo! you may double your bet if you so wish to.

5) You can play single deck at any time.

As is often the case, when visiting an actual casino, the one-deck tables are often crowded. (Assuming the casino you are in even HAS one-deck games.) At Yahoo!, since you can create your own table, you can always choose to play against a single deck.

6) You can choose whether you want the dealer to hit or stand on soft 17's.

Until Yahoo! fixes their oversight, (assuming they even wish to) you should go against what would normally be true and play on a table where the dealer hits soft 17's.
