Yeah, I gave up on position 4, looks like I'll be rank 7 from week 4 onwards. If it happened in a real game, I'd have resigned in a won position

Awesome one, well done Ed!

Week-4 is up.

Made it harder, I hope, to shake the top of the tree.

Please read the instructions in the comment section of each position carefully!

For position 1-3 contribute the mate in x number.

For position 4, the move to draw scores 1 point, the first 6 moves of the mainline scores 2 points. So, some of you can score a +100% score

For one of them, I think that the standard solution is probably wrong.
I am checking that right now.
The other 3 were easy

Four entries so far and 3 got 2 points providing the correct mainline for position-4. I made that visible by adding an extra column called Bonus.

Nobody so far got position-2 right, contributed numbers fluctuate with an interval of 18! We will see next week.

Are you certain you know what the correct number is?

For one of the problems, the stated mate distance from YACPDB is definitely wrong.

Not entirely, but I had the previous right

Correct, it was not mate in x but mate in y where y=x-(sqrt(49)-log(10000))
