Sometimes you wish you could pass the move to your opponent without making the slightest change in the position. Of course, the chess rules forbid this. But in the following position discovered with the help of SEE, you can "break" the rules!
1. Kf4! (zugzwang) (1. Nbc5? Nb6! =; 1. Nbd6? Nc7! =) 1... Nb6 2. Nbd6 +- (zugzwang) 1... Nc7 2. Nbc5 +- (zugzwang)

SEE also confirms my suspicion that the only position with similar properties having fewer than 7 pieces is one discovered by me last year:
1. Bh4! +- (zugzwang)
