The first test match against F5.32, 5min/game, 12 games, was won by F6b impressively = 9.5-2.5. Under the same conditions F6a got 6-6. The second match was a Gountlet. Again 5min/game. F6b won every opponent convincingly. The best result for opponents was that of Hiarcs 7.32, which lost by 2.5 vs 3.5 points of Fritz. Others were simply killed. The third match is in progress. 60min/game. Gountlet. Opponents are Hiarcs 7.32, Junior 6a, Crafty 17.11 (Chessbase) and Fritz 5.32. There will be 24 games total. Game 3 in progress and Fritz is +1.50. Both previous games were won by Fritz 6b. Conditions: I use the Light.ctg which comes with F6 demo. The reason is that I want to see engines thinking instead of coming out of book at move 30. No tablebases used this time. Didzis Cirulis
