to win, it is enough to checkmate one of the opponent's kings
Double-King Chess puzzle
Sort:
An interesting idea was realized in this problem - the decisive piece first checks one king, and after a while checkmates another king.
The solution:
1. Bo5+ Kp5 (not 1. ... nxo5 2. Rp6#) 2. Qm8+ Bxm8 3. Ri6+ Kxj4 4. Bl2#
This is one of my most interesting Double King Chess puzzles to date.
Okay, the first one was difficult. It's a little easier here.
White to move and mate in 4.
Just to remember: A check to both kings is considered checkmate if at least one of them is unable to escape from this check.
Hmmm

I think I got it - 1.Rxf4+ Kxi3 (...Bxf4 2.Bxf6+ Bg5 3.Bxg5#) 2.Kj6! and black has no move to prevent Bk5#. Both black kings are stuck on the diagonal and black can't save them both.
Very nice puzzle.
You are absolutely right! Thank you!
The well-known example of rook and king checkmate against a bare king on a standard 8x8 board can also be used here.

Very nice puzzle.
does it mean Ki2 (after Kj6) will save black? it can escape from Bk5

But the other not. So it's a checkmate.
if Bk5 and then just take the knight, the other escaped

I didn’t pay attention to it. Just misunderstanding. You're right. The correct first move is Kj6 and everything is as described above. 1... any 2. Rxf4 etc
1. Kn7 Kp6 (1. ...Kp8 2. Ra5) 2. Ra5 Kp7 3. Rp5# or 2. Ra5 Kc1 3. Ra1#
Last one, guys. I promise.
White's position seems hopeless. However, there is a way to win.
