Hi Queegmeister,

Igor or the identical Grand Master can be tunened easily by changing the crystal from 12 Mhz to 24 Mhz an S type (standard or groung tone) is needed.

The clock now runs in double-speed, there is no way to avoid this.
After tuning you can play for e. g. 30sek/move with level 58 (1 min/move) or blitz with whole game in 5 min with level 75 (game in 10 min.).

Unfortunately there are no corresponding levels for tournaments, so the tuning is useless here.

Regards
Achim
