"Harold's database today is a must for endgame study composers and judges; ignoring it is like having to rediscover America again and again, in this way wasting both your time and reputation. 8000+ new pieces, references to the EG magazine and to anticipators, exact dates - again it represents a lot of invested effort"
- Emil Vlasák, Czech Republic.
