DiepX for example won a 75 10 game. Note that searching at icc for amateur doens't work as it's rating is too low to store it in library idem for diep i think, but a single loss already is worth 16 points. A few of those losses, we talk about just needing like 5 of those losses and you lose already 5x16 = 80 rating points which means a lot for any ranking. ICC ratings are very fluctuating because they use K=32, where according to FIDE k at 2300 would be ==> (2600-2300) / 20 = 15 So rating win/loss goes more than twice as fast as at fide. For programs above 2400 rating loss/win goes more than 3.2 times faster than at FIDE, as K factor is above 2400 at fide: 10. for those who don't know what a k factor is: it is the number of points you can at maximum lose. So playing against an opponent with about the same rating (within 2 points difference) means you need to score 50% against him, 0.5 x k = 0.5k So a 2300 winning against 2300 loses at ICC 16 points. 2300 at FIDE loses 7.5 points. a 2400+ against a 2400+ (both same rating) has 5 points at risk, at ICC it's still 16 points at risk.... Quite a big difference! >>BugChess 2284 2314 | 92% 48 100 | 2297 2270 14 >>ArasanX 2222 2263 | 33% 2 6 | 2222 2208 14 >>EXchess 2224 2243 | 0% 0 1 | 2262 2224 0 >>Tinker 2222 2202 | 81% 55 115 | 2222 2033 14 >>Hossa 2155 2174 | 37% 40 85 | 2259 2155 7 >>stormx 2065 2065 | 55% 8 9 | 2065 2046 7 >[snip]
