# Grasshopper Chess: Maximummer Mates and Stalemates

In Maximummer problems, Black is restricted to making only his longest moves. The moves must of course be legal, so they cannot be selfchecks
and if the BK is in check the move must be the longest move to stop the check. If there are several equal length moves any of them may be taken.

A three-step diagonal move (length √18, where 18 = 3² + 3²) is longer than a four-step lateral move (4 = √16).
A four-step diagonal move (length √32, where 32 = 4² + 4²) is shorter than a six-step lateral move (6 = √36).
A five-step diagonal move (length √50, where 50 = 5² + 5²) is longer than a seven-step lateral move (7 = √49).

Maximummer Selfmates are now on a separate page.
