‘Tries’ are white first moves that very nearly solve, but
fail to only one black reply. Composers love tries, because they make
the solver think he’s done the job when he hasn’t. This one
is a hornet’s nest of tries:
White to play and mate in two moves
This is a ‘miniature’, meaning that the total number of men
is less than eight. Should be easier? Not always, as fewer pieces
means more scope for each one! It’s soon clear here that you need
to move the knight on e4 to be able to mate against moves by the black
king, but where to? The tries are 1 Sxg3? Kf4!; 1 Sf2? gxf2!; 1 Sd2?
Ke6!; 1 Sc3? Kd4!; 1 Sc5? dxc5!; 1 Sxd6? g2!; and 1 Sf6? d5! So the
solution is 1 Sg5!
There’s little you can do with a problem like this other than
carefully work through all the tries until you have eliminated all but
one, although capturing key-moves are rarely correct, so at least you
can guess that Sxd6 and Sxg3 are probably wrong.
Notice that in this one the white knight visits all its eight squares
between the tries and the solution. This is a knight tour. White
knights tour and black knights wheel – as in the Mansfield problem
in Part 1. This problem is by G. Latzel and appeared in a well-known
solvers’ magazine, ‘Die Schwalbe’, in 1956.

Correspondence Chess Association magazine ‘Correspondence Chess’ in 2010.
