J9 has gained much strength compared with J8 in Blitz games. In fact, i thinks much much faster and did no longer loose games by time in quite winning positions. Compared with the other engines i made these tests: each time 20 games match of 3mn per engine, using 10 testset positions composed of openings reached at least after 5-6 moves, Learning function set Off for the Shredder's: Here are the results (by far much more better than J8), but i think that testing it in longer time controls like 3mn + 2s or more will enhance his performance: J9 - Sh8: 8,5 - 11,5 J9 - Sh7.04_Haddad1.2DP2 Setting: 7,5 - 12,5 J9 - DF8 : 11 - 9 J9 - DF7 : 12 - 8 J9 - Fritz in Bahrein : 12,5 - 7,5 J9 - Fritz 8 Bilbao : 7,5 - 12,5 These results are quite representative of the strength of the new J9 engine. I tested the 9.0.1 version. I was really impressed by his attacking skills. It's the most aggressive engine i ever saw. In each of the matches played there were at most 30% of the games that ended with draws due to extremely edged positions. but i still find that Junior 9 has a lot to do in the endings. In his matches vs the Shredder engines he found extreme difficulties to hold on. but he succeed to save some points due to the fast time control. The only match were there was more than 60% draws was against my Shredder 7.04 with Haddad1.2DP2 Setting. My baby is still among the best engines. He wins all his mini-matches of 20 games except against his brother Shredder8 who's the only capable of beating him in 20 games or more matches.
