'I'm glad you like these questions' -- I have always (well, at least since
I started publishing CV writings in the early 1970s) appreciated the
value-added that asking these questions can give to your new game.
Before you ask, you should either know the answer or suspect that the
answer will be really interesting.
The 'standard' questions are::::::::
1. Shortest foolsmate (for some games, shortest victory)
2. Shortest doublecheck (triple check, quadruple check, etc.) with or
without mate
3. Shortest stalemate; 4. shortest stalemate without capture (the great and
brilliant and superhuman Sam Lloyd solved these for FIDE Chess; if you
don't know his solutions, look them up and you will feel the emotion known
as 'awe' -- really, no exaggeration, awe.)
5, shortest perpetual check, 6. others appropriate for specific variants.
