Usually people do something more practical in their lives that finding forced mates. These positions have one practical objective for those that have not that much practical mind - they help in tuning mate solver to best possible speed. Other positions, that look like to be from real games, are also very useful for mate solver tuning and verification. Positions different from present (usual, or almost usual) I created by thousands around 5 years ago. Some of them can be found on the Web Site with my mate solver (LLchess). Cheers, Leonid. >Hans.
