Are they?

Post by Dann Corbit » Mon Sep 23, 2019 11:48 pm

These are supposed to be checkmates at the depths listed. I did not solve any of them

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

What is the source of these positions?

Don't know. They were in my database, mostly without attribution, and unsolved.

This one is from the sting collection:
bm #22;

And this one:
bm #46;
is annotated as ECE3.1020
Online tablebase files show the mate is correct, but I do not have the full path.

The other one with a note:
bm #53;
says: tb04 {m}; 1891; Amelung F; 1-0
So I guess I might find it in yacpdb, pdb server or some other problem solver base.

That third one was on Yacpdb:

Kg7 Kd8 50. Kf7 Qxa7 51. bxa7 Kc8 {eg} 52. a8=Q b5 53.
axb6 a5 54. b7+ Kd8 55. Qxb8# 1-0

I turned this one into an EPD chain, and I am analyzing in reverse.
It looks like several of the problems are from this single problem

Let me clarify:
I know the key move and proposed mate distance. I lack a mechanical (computer generated) correct and complete plan.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

In 10 mover probably intended solution is

1. Rb8+ Kxb8 2. Qb1+ {10} Qb5 {0} 3. Nxb5 {0} Nf3+ {0} 4. Bxf3 {0} Kc8 {0} 5.
Nxd6+ {0} Rxd6 {0} 6. Qb7+ {0} Kd8 {0} 7. cxd6 {0} Nd5 {0} 8. Qb8+ {0} Kd7 {1}
9. Nc5+ {1} Kc6 {1} 10. Qc7# {1}

But black is not forced to take rook at all :) .

11 mover is clearly fake as white cannot mate at all.

Others too long for engines.

For number 1 that's the best I could find. plan on looking at the others as soon as time permits.
