Here's game ten of my little tournament. In an English variation (symmetrical) first played by Korchnoi-Spassky 1977, as as far as I see (11.Be3), the opening followed Vaganian-Portisch 1988 to move 17 and became a draw like this. After Junior getting a pawn right from the opening Fritz did not manage to get enough compensation by active piece play. But as late as after 37.f5 Fritz won the pawn back for a short time in a complicated tactical battle, just to face new problems when now Junior got enough pressure to get the pawn advantage once more, still having some pressure. The Queen-Bishop ending was funny: Fritz5 pushed the white king to g5 just to exchange pawns, obviously not fearing that the "active" king could be hunted. After some checks Junior5 could have exchanged Queens in move 68 to another drawish bishop endgame (white king centralized), but preferred to continue the king hunt without success either. After further exchanges in move 91-94 the queen ending was dead draw as indicated by the tablebases.

But a look at the *content* of the games played confirms that Junior5 is definitely very strong and even should be able to fight for the top of the SSDF list, as long as no other new programs coming soon (Rebel 10, Mchess8, Hiarcs7, Genius6) will play even better. I am uncertain if I should include more programs (Crafty 15.19, Shredder, CSTalblack and others) in the testing or rather play a re-round with the same well known top programs from the list above. I have no time for manual testing, so I can't include deKonings CM6000 engine, which would certainly be interesting enough, and I don't have the strong Nimzo 98 so far. Kind regards from Dirk
