Hi, This graph is draw rate and black winrate against even opponent in CGOS 9x9. http://www.yss-aya.com/20200704cgos9x9.png Blue is black winrate. Red is draw rate.
The higher rating, the higher draw rate. If it keeps going this way, all the games will be draw in 4500 ELO. In black winrate, it seems the higher rating, the less than 50%. There are from 110000 games from 2020-01-01 to 2020-06-30. For example, draw-rate between programs in their 3300s are 0.444. ELO games b-win draw w-win black winrate draw-rate 1800: 32 =( 18/ 0/ 14), 0.563, 0.000 1900: 0 =( 0/ 0/ 0), 0.000, 0.000 2000: 62 =( 28/ 7/ 27), 0.508, 0.113 2100: 296 =(132/ 23/141), 0.485, 0.078 2200: 0 =( 0/ 0/ 0), 0.000, 0.000 2300: 33 =( 14/ 2/ 17), 0.455, 0.061 2400: 68 =( 30/ 2/ 36), 0.456, 0.029 2500: 122 =( 54/ 10/ 58), 0.484, 0.082 2600: 280 =( 98/ 45/137), 0.430, 0.161 2700: 51 =( 23/ 9/ 19), 0.539, 0.176 2800: 582 =(245/153/184), 0.552, 0.263 2900: 1458 =(570/433/455), 0.539, 0.297 3000: 554 =(153/196/205), 0.453, 0.354 3100: 450 =(116/157/177), 0.432, 0.349 3200: 131 =( 34/ 52/ 45), 0.458, 0.397 3300: 124 =( 22/ 55/ 47), 0.399, 0.444 3400: 0 =( 0/ 0/ 0), 0.000, 0.000 * GNU GO is 1800 ELO.
