The game vs. Adams was a Ruy Lopez exchange. This is surely not a blocked position. It was an ending, quite open with White having the better pawn structure and Black having the two bishops. I absolutely do not count this one as a blocked position. In a blocked position the situation of the pawns is thus: They face each other and can't move. Clearly this is not the case in this game. >I also do not think that it played clearly open positions against Bareev or >Huebner. Huebner tried to block the position but he failed. And at the first opportunity he made a big tactical mistake, and committed another one by resigning too early. Bareev sacrificed a pawn early on, so it had nothing to do with the type of the position. The only question in that game was: Can Bareev prove he has enough compensation or not. The ending was quite tricky, also having nothing to do with blocked positions. Besides, you (and all the others!) do not come up with arguments to prove that I am wrong on my thesis that computers obtain GM results, but that their knowlegde is far behind. Does nobody want to disagree with this!? Nobody wants to question my remark that calculation power doesn't solve the problems computer programs are still facing!? Come on guys! I started my love for computer chess in 1980. I played the challenger 7, 10, Voice and won easily. They were weak in all aspects of the game. Then came Turbostar, Super Conny and still these were weak in closed positions and king's attacks. Then I bought my first 'real' computer, the Mephisto MM 4. I liked that one very much, because it played positional chess. Ed did a great job there. With fast hardware he would have beaten Richard Lang easily with the MM 4 program. Still, the same problem appeared: Although the MM 4 knew more about blocked structures, it could be beaten by King's attacks or long term plans. After MM 4 I got interested in PC programs. Gideon, The ChessMachine, Genius were the first one. Still the same problem: No good plans in blocked positions, no understanding for King's attacks. Now we are 10 years further in time. PC's are 100 times faster (I am not sure about this figure, I estimate it) and DJ plays on a super PC, equalling 4,5 GHz. And what do I see: NO understanding of blocked positions, no understanding of how to prevent or defend against a king's attack. Conclusion: I am in the computerworld for 20 years. I saw them starting with less than 1000 Elo. Now they have above 2600. But two problems remain, they were not solved in 1980, not in 1990 and not even in 2000: Blocked positions and king's attacks.
