It means almost 300 elo points more. With that difference GM Adams only >can draw, and this is very hard to believe. We will see. Elo figures with a small number of games have very low precision. Really, all we have for something like Hydra is a TPR sort of measurement. It will take hundreds of games in tournament settings to develop an accurate Elo figure. The number probably does not mean what you think it does anyway. A figure of 3000 Elo could be accurate. But here is what the number would represent: 1. Given the exact pool of opponents which were pitted against the machine 2. Given the exact playing conditions that were used in the matches then a rating difference from the 3000 figure against those opponents and under those conditions can be used to predict a broad result against a class of oppoents from that list. This value CANNOT be used to predict the outcome of a single match even with the exact same opponents used in the calculations (except on a broad probability basis). This value CANNOT be used to predict the outcome against a pool of competition against which the machine has not been tried. We can extrapolate that a machine that did very well against (for instance) Shredder would probably do very well against humans. But it would be pure guesswork.
