100 Headaches

100 extremely difficult mate in 2 chess puzzles.
Based on the book 100 Headachingly Hard Mate In Two Chess Puzzles by Sam Loyd by Martin B. Justesen.

Gameplay

It is white to move on every puzzle. But the player ALSO makes black's move rather than a computer-automated response. That way, you can try out different moves for black to prove to yourself that it is, indeed, mate in 2.

Scoring

Plus 5 for every correct move. Minus 1 for every wrong move. Only on unsolved puzzles. Once a puzzle is completed, you can replay it as many times as you like and not lose/gain points.

Navigation

All progress is automatically saved. There is a handy 'map' of all 100 puzzles and you are free to jump to any number you like.

I do not expect anyone to finish this. Let alone with a positive score. But if there is a true masochist out there, please share a screenshot!

Thanks to @phil for helpful feedback on my last cart. It made this cart better.

I'm really enjoying this cart @camp39 but wow is it tough. Never thought I'd enjoy chess puzzles, but I've got into a rhythm of looking at a puzzle, going off to do something else whilst mulling over the pieces, then coming back to find out my idea was totally wrong!

This one is absolutely brutal. Cool that you can see it in your head. These ones are so nasty that I just brute force them and laugh at the solution. The cart after next will be much less painful!
