Aces are the strongest cards in the game of blackjack. This is because of their ability to be counted as an 11 or a 1. That flexibility is what makes them the strongest card.
Not to mention the fact that they are essential to having a natural blackjack.
But Aces are also strong because of how they work with pairs.
I have discussed how, when dealt a pair of Aces, you need to split them. This is because it increases your blackjack odds because it increases your chances of making money.
But there is another house rule that further increases the flexibility of Aces. And in increase in flexibility further increases your blackjack odds.
Sometimes casinos will allow for players to resplit Aces. This means that you are dealt a pair of Aces in your first two cards, you split them, then at least one of those new hands receives another Ace forming a second pair of Aces.
A fair number of casinos will not allow players to resplit such a second hand, and you would be stuck with a soft 12.
However there are times when the house rules are changed a bit, and players are allowed to resplit Aces. This house rule takes 0.06% away from the house’s edge because it increases your chances of winning and decreases their chances of taking your money.
While 0.06% is not a huge hit to the house’s edge, some is better than none. Blackjack strategy is about increasing your chances of winning which increases your blackjack odds. So even though resplitting Aces is not a huge decrease it is still a decrease. On top of that a second pair of Aces is not a common happening which is another reason for the low hit to the house’s edge.
But it should still be worked into your blackjack strategy for the hit it does to the house’s edge.
