Solution of a deck of playing cards

As long as the stall owner's brain is not funny, if the rules can't be flush, he wins with the right A pair 10. (this mess is actually a test of psychological quality. If you get the right A to 10, you may not win because you are nervous and can't grasp the timing of A or 10. If you miss one step, you lose. )

The first three cards are like this: 3 Q 4 4, the opponent will not press any one. Next, no matter how you play, you will lose.

The first type: you 5 him 10 you k, he doesn't press, you 5, he doesn't press, you 6, he presses 10, at this time you have a single six, you press 10 to score q or k, forming a double order, and then he presses a single a to win.

The second type: you open Q or K, but he doesn't press it. If you open a cam, he will press 10, and his death will be even worse.
