Gothmog might play well in some common opening positions and horrible in other common positions. It tends to push pawns and this is of course not always advisable. Personally, I don't like rating lists based on a few opening positions. 10 (or 20) popular opening positions are definitely not enough. The results are more or less a matter of luck, even after 100's of games. Michael
