The Title should be Mate in FIVE.
(unless one of you guys find one in four).
This position arose in a game of HAL CHESS.
In HAL CHESS there is glich in the program.
If you capture a piece on certain squares then that captured
piece re-appears once the capturing piece has moved.
Eg: Suppose one of the glich squares was e7
If the Knight on e7 had captured a Black Knight on e7 and
White played 1.Ng6+ Black could play 1...Nxg6.
Determine which square is the glich square. Determine what is
about to re-appear. White to play and Mate in 5. (very easy).
(Next Problem - How do you edit the title? There is a glich in my brain.)
