When do you raise your bet in blackjack?

Answer 1

When to split is up to the player. There are no specific rules about it. However, the most experienced players will tell you to; always split Aces and eights, never split face cards or tens (a 20 is a darned good hand), don't split when the dealer is showing an eight, nine, ten, or Ace. Fours, fives, and sixes usually end up being 14, 15, or 16 (losers). The best time to split any pair is when the dealer is showing a 3, 4, 5, or 6. Deuces (2) are called a dealer's Ace, the dealer will make a hand more often with a deuce showing than any other small card. Remember it is gambling, no guarantees that something will work the same every time, casinos were not built by winners.

Answer 2

The question raised is typically for people who count cards because the casual player would raise their bet base on feel or a hunch. There is no way for the casual player to know when to raise their bet unless they have prior knowledge of the next card to be dealt.

Now, if the casual player wants to raise their bet base on the basic strategy in blackjack, then it would be during the opportunity to double down on a hand or double down after a split (if allowed by casino). I find it the only time one can raise their bets. The basic strategy calls for doubling down when you have an ace showing or ten or face card showing (if the dealer shows a card from 2 to 9).

There are many variations but the suggestion mentioned above is a must. Good luck!
