No Double after Split (NDaS)
What is 'No Double After Split'?
No double after split is a restriction that can be placed on a blackjack game
to prevent the player from doubling down after they have already split their cards into two separate hands. This restriction is usually put in place to prevent the player from gaining a further advantage over the house, after already benefiting from splitting their hand and hence having a better chance of being able to predict the outcome of the next hit
or card turn.
'No Double After Split' ExplainedDoubling down
involves the player increasing their initial bet by up to 100% on their two-card hand before the next card is turned. The sacrifice for doubling down is that the player must then stand after receiving the next card, regardless of its value. This is usually performed if they're confident of their hand beating that of the house, or simply if they're feeling lucky
' can be performed if the first two cards of a hand
have the same value. The effect of a split is that the two cards are separated into two new, entirely independent hands, with an additional bet made by the player on the new hand. The two hands are then played as normal, with an additional card drawn on each hand so the player has two separate two-card hands.While a player is perfectly entitled to double down on a regular hand, this option can be restricted or revoked if the hand in question is a result of a split. This is to prevent a player from doubling their bet on an advantage they have already gained as a result of splitting their hand. Denying the player this move will increase the house edge by around 0.12%.
