+49 =33 -18 is the impressive result GambitTiger 2 aggressive (GT2a) reached vs. the strongest competitors available. This 65.5-34.5 takes GT2a 4 points ahead of ChessTiger 14. Honestly speaking, this is not very much considering the distance of 100 games. So there shouldn't be any definite conclusion about GT2a being stronger. For advice ask the engine you like most. GT2a e.g. won 9 games while CT14 won only 4 games within 40 moves. On the other hand ChessTiger plays more solid. A clear vote for one of them really makes no sense. Interesting is that in SSDF the normal GT2 is a bit in front of CT14 (not in my tourney) due to two differences: 1st SSDF has played several hundreds of games, I have only 100 each; 2nd SSDF plays without the original CT14-book. Maybe the SSDF-guys get inspired by my test results of GT2a and test this settings too. I'd be glad to see that but I fear they will not do this because my tourney does not really show a convincing result and probably one GT is enough for the list...what would be a pity indeed. Maybe the members here write to SSDF and ask for this testing?! Finally in my tourney I will test GT2a with a changed setting in the ct.ini, SelSafety=8 instead of 6 which is default. This makes Tiger a bit less selective and he might not miss some move which makes him win instead of draw or so. The disadvantage of course is that he does not come so deep in the search tree so that he might miss something important. So to verify if the advantages at least equalize the disadvantages, I will play the last turn of my tourney, 90 games to go (10 have already been played vs. Shredder5), the fight vs. Shredder 5.32 has just begun this morning.
