He DOES follow CCC and was intrigued (as I was) by the fact that the King Safety values of most of the "superior" personalities that are posted here are much higher than the default value of 100 -- usually somewhere between 130 and 160. So, Johan decided to go with an ASYMMETRIC KS value of 100,140, meaning it is concerned about its OWN King Safety with a value of 100 (the default) but it is concerned about its OPPONENT'S King Safety with a value of 140. Here's Johan's explanation of why he chose this configuration: ----------- Though I was tempted to use Kurt Utzinger's, I later rejected this jump in the dark. But then you mentioned the KS pattern on CCC, and I came up with the following rationale (no proof!). The merit of high KS is that the computer opponent will be more likely to face lethal mating threads. On the other side, it tends to "chickenize" TK himself, which might cramp its style in wild positions. Against the average program TK should not need to be defensive on the King's side, hence the asymmetrical weights. ----------- This could very well explain moves like 25...Re5? that Vine Smith was questioning -- a failed attempt at a kingside attack. As a side note, he also used Selective Search=10, but that's ONLY because he got an Athlon 1.3GHz machine just before the tournament. If he had used his trusty 550MHz instead, then he would have stayed with SS=6. jm
