For this Fairy piece there is a forced mate (K+FP vs k) in 125 moves: rWbrFfDlfflNlA

Can anyone create a piece that can force a checkmate in more moves?

Ok. So far we have fWbrFfD2lfNfrblA from Bn Em with a record of mate in 159! I haven't been able to improve it yet. The challenge is still on!

Ok. I'm ready to declare a winner. In the 8x8 the fairy piece that delivers mate (major) on the most moves is: fWbrFfD2lfNfrblA with 159 moves from the most difficult position. I tried may other combinations and could not improve it.
