Stockfish 180326 on my old test suite (161 positions)

Post by Vinvin » Mon Apr 09, 2018 10:12 pm

Conditions :
5 minutes per position on an I7-6*4 GHz, 6 pieces Syzygy, 8 GB HT.
3 runs, 3 columns in the tables.
Stockfish becomes very good in solving this set. It improved in some fields, mainly zugzwang and sacrifice to mate but it still not perfect.
Number of positions found at least one time : 116 on 161.
Position never found on the 3 runs : 45 on 161. But 8 of these 45 are flawed or suspicious.

This session helped to recheck most of the positions.
I recap all the positions next, with colors in a screenshot :
Yellow : become too easy (32 positions).
Red : bad test because of errors or duplicate solutions (9 positions).
Orange : still unclear (4 positions).
Green are special positions : shortest mate or evaluation to check (9 positions).

The whole EPD set is at the end.
Hopefully, it's the last time I use this bad quality set.
