GLOBAL SCORE AFTER 960 GAMES: 370.0 – 590.0 = 38.54%
Average Elo of rivals= 3.247
Estimated ELO for Deep Shredder 13 = 3.167

Deep Shredder 13 against:
Komodo 10.2 (3277) = 32.71%
Sugar2.6 (3291) = 33.75%
Houdini 5 Pro (3316) = 26.46%
Gull 3 (3103) = 61.25%

Unfortunately I have not been able to find my previous tests with Deep Shredder 12, so that I can not compare the evolution of Shredder's.

Although still 168 Elo points below the top leading engine Stockfish 8, the evolution of Deep Shredder 13 is excellent. According to this test, it has performed 31 Elo points better than Houdini 4 Pro and 64 better than Gull 3.

Well done!

64 better than Gull 3

Have you considered LazyGull? I noticed a 50 ELO points improvement, at very fast time controls, over Gull 3.

I was not aware of this LazzyGull, Juan. I will try to find it. 50 Elo improvement sounds quite impressive to me.

Thanks for your advice.

I instantly get a segfault on starting up.

Same thing happens when I build it myself with pgo.
