There are a few long mates in the problems considered so far.  WAC.006 and
WAC.163 are both mate in 11, and WAC.041 is a mate in 15.

WAC.006:

[D] 7k/p7/1R5K/6r1/6p1/6P1/8/8 w - - 0 1



WAC.041:

[D] 1k6/5RP1/1P6/1K6/6r1/8/8/8 w - - 0 1



WAC.163:

[D] 5rk1/2p4p/2p4r/3P4/4p1b1/1Q2NqPp/PP3P1K/R4R2 b - - 0 1
