Hi,

As far as I can tell about the Sparc, it completely failed in the openings, being out of book several times after 3-4 moves only !
Against the Risc 2500, it was good for the Sparc and it took the lead quite fast, but in the other games, it was lost very soon after the opening :
1) against the Sapphire, the Sparc made a dubious exchange at move 13 and completely blundered at move 15 with Qc6 (Fritz 10 evals jumps from +1.2 for white to +3.5 with this move)
2) against the Risc I, it was completely beaten in the opening : out of book at move 4, and its position deteriorated very fast (-1.5 at move 14)
3) against the Berlin pro, it was also out of book at move 4 or 5 and played a series of bad moves : -1 at move 10, -1.8 at move 14, ...

Strange games indeed...
Best regards,
Alain
