Thank you Walter!

[Jouni]

Thanks, finally a suite which ain't too easy for top engines! I tried 5 engines with 1 minute limit (dual PC). Scores:

Houdini 36
Critter 33
spark 27
Rybka 26
Stockfish 18

But it's difficult to quess how many are solved in 10 minutes and 8 core...

The easiest positions with at least 4 solutions were 13 16 18 20 28 41 69 70 77 81 and 82.

Does anyone have the .epd file for these positions?

Does anyone have the .epd file for these positions?

This download will uncompress to 2 files (1 epd, 1 pgn):

Too bad bm (best move) is missing from the epd...
