At first I thought that the programs had a rating around 2550. After the initial games against GMs, I passed to think the rating should be 2450. I think today that two factors can make the rating to be close 2600 (will be that I am being very optimistic?). 1. A specific opening book . 2. Ed to program the games with less antecedence, not giving to GMs the advantage of a long preparation. Paulo
