Re: White to play and Win, only for top 7 engines

Post by peter »

Question should rather read like "which one of the top 50 engines of nowadays cannot solve that instantly?"
Tried some of them down the rating lists, eg. Fritz18 (which btw is very good at (for engines) easy puzzles like this one of course), Fritz15 (Rybka) and Chiron 5.1, none of them having any difficulties (as for time to solution > a few seconds) with it neither.
Here's the original study as it's stored in HHdbVI, by me added three lines (including expansion of author's line to mate) with (as for the puzzle itself of no meaning not being a #in x- one) longest DTM and two corresponding comments.

Re: White to play and win, only for top 7 engines.

Hello:

This great study only got a 5th Honourable Mention according to YACPDB!

https://yacpdb.org/#276200 (YACPDB has a slightly different position from the original source).

I managed to find the original sources of first print and solution: Nº 07 and Nº 13 of Chess in the USSR of 1933:

This is the Study Nº 631 at page 99 of the Nº 07 issue:
COMPOSITION DEPARTMENT

All problems and studies of this issue are printed for the first time

Study Nº 631
A. Kazancev, M. Liburkin (Moscow) and L. Staroverov (Minusinsk)

White wins
The solution can be found at the end of right column of page 196 of the Nº 13 issue:
Nº 631 [...]
1. b5—.b6 Be8! (Now you can't play 2. b7 right away because Bb5 3. b8Q Bf1 4. Qb1 K:h2 5. Q:f1 — stalemate or black creates a fortress with Bh3)
2. Kc5! Bg6
3. Kd4 (White menacingly approaches his king) Be8
4. b7 Bb5
5. b8R! Bf1
6. Rb1 Kg2

Thank for finding out that information, but I will NOT search for days like you did to see if a particular puzzle has been posted or NOT :roll:
