I have Chrilly's permission to post these remarks he emailed me about Hydra: "Winning against GMs has to a certain extent already lost its charm. We are already in the position were we can only lose. I personally think that this expectation overestimates the capabilities of the program. But it is a matter of fact that this version played 8 games against top GMs, won 6 and made 2 draws. Gives an Elo-rating of >2900." "Leonxto (Leontxo García, well known chess journalist from Spain) wrote in El Pais: "y ademas muestra uns unaudita "comprension" de la estrategia" (and it also shows an unheard of "understanding" of the strategy). Actually it has no idea at all about this. It has some simple rules like "It is beneficial to attack the area around the opponent king, to attack opponent pieces, to control the center. It knows a little bit what abut bad/good bishops, when is the knight stronger than the bishop". The big surprise for me was, that even this simple rules were sufficient to know that the exchange of the light-squared bishop of Ponomariov in the first match was not the best idea. The evaluation went up a 1/4 of a pawn. Generally I saw no GM move which had some flavour of geniality (I am speaking only of the Hydra-games). The moves which really surprised me (e.g. Qe2 after Nc4 in the last match) were done by Hydra."
