A program that learns to play a variant of the card game "Blackjack" in the same way as the AlphaZero program.

Game

• They are each trying to reach a sum that lies in a specified target, between a fixed low value and high value.
• If a player reaches a score in the target range, they immediately win; If they exceed the high value, they immediately lose.
• The players can choose the number of dice to roll on each turn, between 1 and a fixed maximum.
