In a real-world case study, different blackjack game scenarios were systematically examined to assess the effectiveness of the insurance vs. split strategy. According to the data from multiple rounds of the game, it is relatively rare for players to choose insurance at critical moments, and this strategy is usually considered when facing a dealer with an ace. The analysis shows that the probability of scoring for the player who chooses insurance is only about 30%, which is significantly lower than the success rate of continuing the game directly, so insurance is not a wise move in most cases. Comparatively speaking, the split strategy shows more flexibility and success against the dealer's strong hand, especially when the hand is 8,8 or A,A, the win rate of the split can be increased to 55% or more, contrasting with the 31% success rate of the non-split.

In the quantitative evaluation of strategy effectiveness, we constructed a table by counting the change in win rate of various types of players after implementing different strategies. The table lists the comparison of the win rates in the insurance versus split situations, as well as the success rates of different starting hands, which provides players with clear data support. Based on this study, we suggest that players should be more prudent in choosing insurance in their games, and more proactive in using the split strategy when they have stronger hand combinations, in order to maximize their win rates.

starting hand Insurance win rate percentage of victory in a split decision
A, A 20% 55%
8, 8 15% 57%
10, 10 10% 50%
