However, this problem is not computer tested, so there is a possibility of cooks.

This is the starting position:



After 1.bxa1=B 2.Bxe5 3.a1=B 4.Bad4 5.c3 6.c2 7.c1=B 8.Bcf4 9.g3 10.g2 11.g1=B 12.Rg2 13.Rh2 14.Rh1 15.h2 16.f2+, white plays Ke2 ending with this stalemate position:

...er......you just beat me to it by about 100 years.



Black has to make 16 moves on the bounce and then White stalemates
Black with his next move.

To see Mephisto's solution in action I've added a Knight that will hop
back and forth between a7 & c8 as a move waster.

How about an easier one before SG will undoubtedly test us more.



Series helpmate in 17 moves. Black plays 17 consecutive moves, allowing white to checkmate black in one move.

What does the term cook mean in the context of a chess problem?

Thanks

Disclaimer - none of these are actually my compositions, but I tend to withhold the composer's names to avoid people just looking them up.
