Hi all of you, to get some more impressions of Junior5's blitz strength, I played some games on ICC against strong human and computer opponents (the latter often running on much faster hardware). I used a simple 200MMX and 24Mb Hash, having to play manually by switching between Junior and "Blitzin" (the ICC chessboard interface) in Win 95. As I am a comparably slow switcher (I saw others do that with considerable speed) I lose at least 3-4 seconds/move for manual switching, leaving only the rest to Junior, thus slowing the program down additionally compared to programs answering automatically as well as against humans who have the whole time just for thinking and giving in the moves on *one* board. In spite of these somewhat difficult conditions Junior5 achieved an ICC rating of 2762 meanwhile, which looks to me to be the best ICC rating of a program on 200MMX (not counting manual operating) at the moment. Bob Hyatt or Bruce Moreland (whose Ferret on a fast Alpha running automatically seems to be top there) can correct me if I am wrong... (ICC ratings are not comparable to usual Elo ratings: the highest ICC ratings are around 3000 by some bullet [game in 3' or 1 '] specialists who seem to have concentrated on either winning or winning on time :-) against anybody else, anyway by playing faster than others even move... This does not reflect real chess playing strength though in my eyes. GMs are usually blitz rated between 2600 and around 2900 there, as far as I could see). Some samples against two different programs and one GM may demonstrate some of Junior's very versatile playing style (anything from King attack to switching to won endgames) already on Blitz level. I have omitted all names of opponent's, because I don't want to shed any shadow on them, but just show some samples for Junior's play. I hope I walk on nobody's nerves by being more and more enthusiastic about Junior5. For me Junior5 has become the most impressive computer program surprise since Hiarcs6 and Rebel8/9 - not speaking of Fritz5, a program I always regarded as very strong and which I use to defend against unqualified critical verdicts, although it does not quite reflect my favorite playing style.

Junior5 immediately punished this by very sharp play and the GM resigned short after: Junior5 - Grandmaster on ICC [B90] 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nb3 Be6 8.Qd2 Nbd7 9.f3 Rc8 10.g4 Nb6 11.0-0-0 Be7 12.h4 0-0 13.h5 h6 14.g5 [Junior's first move out of book and an excellent answer to h6] hxg5 15.Bxg5 d5 16.h6 g6 17.Qh2 d4 18.Qxe5 black resigned 1-0 These are just some of many impressions I had. They prove nothing but they tell some to those able to read games with some sense for chess... Just enjoy the games and don't discuss Junior's possible rating with me :-) ... Kind regards from Dirk
