I have played around with various variants of singular extensions from time to time, but never had much success, even in tactical test positions. The problem seems to be that the general search depth is reduced too much because of the many stupid variations which get extended. When I look at my log files, it seems that most of the singular extensions made are for recaptures after obviously losing captures, like the line 1. e4 e5 2. Qh5 Nc6 3. Qxh7 Rxh7. The move Rxh7 is singular, but making an extension in a line like this does not seem like a good idea. Do those of you who successfully use singular extensions employ some technique to avoid triggering the extension in the type of situation described above? Tord
