The last game of poker

Give a 3 first, if not, give a 4, one by one. Until the cards in B's hand can be played together, play together.

If it wants to, there are two situations:

1. If he picks up an A, don't pick it up. Let it play another hand. If an A is returned, press 2, and then play one by one. If it picks up a J, press a Q or K, then turn right, and finally take the remaining one.

2. He answers with J, and you answer with Q, so it can only answer with A or not.

O: If you take an A, you can ask it to make another one, then use two letters, make the right one, and finally take the rest.

No answer: then you continue to play a deck of cards, such as 4, so that J can answer or not A can answer.

If you use J, press Q or K, then press A, then press 2, and then match until the last one comes out.

If it is connected with A here, then it still has A and J. Let it play another card and then press 2, so it has a single card left. You can play the right one first and then the last one according to the method mentioned above.
