Some of your top SSDF programs are not very good positionally, even relative to other programs. GM Alterman's assessment was based on 150 games against 3 opponents. One of the results was 30-20. He said: "it only beat *** because of sheer tactics" "It can play only one opening - the Sicilian" "I'm not impressed by the results and do not like the games" I dumped that version. >I also believe you are wrong about your strange idea that Junior are >positionally at the same level as Super-GMs. The interesting thing with Junior >are that it plays sharp and many times strange moves that really can confuse >humans. > What you call "sharp & strange moves" are positional decisions. They are not based on search. Moves like a5 in game 4 against Kasparov and Bxh2+ in game 5 are based on evaluation. If you think getting pawns & pieces for free, or even a careless pawn move, confuse Kasparov or any other GM you are wrong. They turn gifts into wins with ease. In some positions Junior's understanding of a position does not match a GM's, but in others it understands better than most GM's. In the 3rd game in NY it showed a better understanding when defending the position than the opponent, and that's why it eventually won. >I also don“t understand the choice of openings in the match.
