My results were with 200 MB HT on a 2009 MHz Athlon under Chess Partner interface. Gambit Fruit default switches to Nf5 after 1 hour 15 I believe, but later switches to e5 again. Evals for these two moves can vary and probably neither of them can draw, if Black exchanges Queens and manages to promote the a-pawn, so in that respect it is not such a good analytical test Regards, Eelco
