First, I am _not_ trying to prove that axb5 is better than Qb6. Second, I _am_ trying to prove that "some" computer will conclude that axb5 is better than Qb6, which means _that_ computer would play the move. Third, I don't know _when_ crafty will change yet. I had searched this to depth=25, which took well over a day, and the scores were roughly .08 apart if memory serves. Then a power failure and a bad UPS battery caused the cluster to go down and everything was lost. I have re-started, but it will be at least tomorrow or the next day before I get back to where it was in its analysis. > >2. How could you believe in such a thing that Crafty could find the correct >solution of this position from a deep GM standpoint of view!? Who said I did? That is _your_ nonsense. I am simply addressing the claim "no computer could play axb5 instead of Qb6". Nothing more, nothing less. I'm not trying to prove that axb5 is better, or that Qb6 is better, or that they are equal. I am trying to disprove that statement and _nothing_ else. Any other obfuscationary attempts are simply clouds of fog generated by yourself, not me... > >3. Even if Crafty would prefer axb5 from 8 plies on, it wouldn't prove that >Crafty found it for the correct reasons. How could we research this topic BTW? Who cares? Does DB therefore have to find it for the _right_ reason, or did it just have to find it for _some_ reason, right or wrong? Don't shift the goal when a solution is "in sight". > >4. You said to Ed that Crafty wouldn't go for the three pawns. It gave a >different line. And - you concluded - this proves that DB2 had even better >reasons to change to axb5. I didn't conclude any such thing. I concluded that Kasparov said that Qb6 was way better than axb5. Deep Blue disagreed. Now Fritz has also disagreed and Crafty was within a whisker of disagreeing when I had to restart. All I conclude is that axb5 does not sac a bunch of pawns. It doesn't sac _anything_ at all, in fact. Neither does Qb6. I have no idea where the pawn sacrifice stuff comes from and don't care. The question is about axb5 vs Qb6, nothing more... > Also this conclusion, if you really believed in such >mechanisms, is false. Out of logical reasons.

Here is a surprise for you: the question is, if DB2 was even stronger than >commercial progs at the time. Ed asked some questions back in 1997. Because it >could well be that DB2 - this was Kasparov's theory - could not find axb5. Why >could that be? Because from the picture of the whole appearance and you won't >doubt that Kasparov had a few correct assumptions about it!? I don't think Kasparov had _any_ "correct assumptions" about axb5 vs Qb6, any more than he had about resigning in a drawn position, for example. > >I give these 5 reasons why I couldn't follow you, as I wrote.

Simply because the proof is in the exact text. wrong again. For some reason, as a post reaches a particular length, when I try to add text, netscape crashes, losing everything I type. I tried three times and only _then_ did I first snip everything but your specific comments, and then added my own. Again, a conspiracy in every corner. When, in reality, the truth is so much simpler and easier to understand.. Anybody can go back one post if they want to see what I snipped, so since I can't edit old posts, how could I hope to hide _anything_? >You didn't stop with just laughing about my following you, but you had that >inspiration of a cow walking down a street - _very slowly_. And I wouldn't be >able to follow her. Think for a minute if that is decent or not in my case. I think the metaphor is quite clear. If you can't follow a cow slowly walking down the street, then you _certainly_ are not going to follow my fast-moving technical explanations here. And you have proven you can time and again... > >Here is the quote for you: > >>>>>"We know that??" >That the moves are identical?? >Are you now the PR manager for >>>>>ChessBase or what's going on here? >What FRITZ is saying must be the final truth? >>>>>How could this been proven? >Is chess already solved? >I must confess that I can't >>>>>follow you!

All nonsensical of course. How to _exit_ the aircraft. At 40,000 feet? at 600 knots? Only people that _know_ what is going on should make suggestions.
