Four-by-four chessboard

Bishops and knights are removed

Four moves to checkmate

Many ways to win

I counted nine solutions

But one is special

I'm going to assume this is the intended puzzle:




enter image description here
Mate in 4.




Here's one solution (or four, depending on how you count), I think:



Take twice on b3.
B-pawn takes; discovered check.
Queen to a2, mate.


Or in a more common notation:






1. axb3+ Qxb3
2. cxb3+ Kxb3
3. bxa3+ Kc4
4. Qa2#

If 2. - Kb4? instead, then 3. bxc3#


After ruling out pretty much everything else, here are four more solutions: (found the special one before these, but saving it for last in order to maintain dramatic tension..)



Start just like before.
Queen to A2 on move three,
then mate with a pawn





1. axb3+ Qxb3 (again, white can reorder the first two moves)
2. cxb3+ Kxb3
3. Qa2+ Kb4
4. bxc3# (or dxc3#)



And finally, the special one:



Sac queen on d3:
Exclamation marks galore.
Easy mate in two.





1. cxd3+! Rxd3
2. Qxd3+!! Kxd3
3. dxc3+ Kc4
4. Rd4#

  • Correct, that's one. Actually, that's two. The original notation can be translated into common notation two ways.

  • Changing the second line to "b-pawn takes: discovered check" brings that up to four, even :-)
