[restored topic] Mating in endgames with the Unicorn

When you play an endgame with Unicorn + King vs King, it's in general a draw because the King and Unicorn cannot force the opponent king to go to a corner, sole place where the Unicorn can mate.

The advise when you are a Unicorn up, don't trade your pawns !! (it's the same advise when you are a Knight up).

When you play and ending King + 2 Knights vs King, the ending is in general a draw. With a Unicorn and knight, you can force the mate.

Black plays starting from the following position. Here is the technique:

1...Kc7 2. Kf3 Kc6 3. Ke4 Kd6 4. Nh6 Kc5 5. Ud2+ Kd6
You cut off the road to the Black King

Now begins maneuvering with the Knight and the Unicorn. The main principle is: The Knight reduces the field of the Black king on one side, and the Unicorn does the same on the other side !

6. Nf5+ Kd7 7. Kd5 Kc7 8. Uc4!

An important position

8...Kc8 9. Kd6 Kd8

12. Uc5+ Ka8 13. Nd6 Typical mating position ! Beware of stalemate !
