Weekend seminars are both, fun and effective. You meet with like-minded people, possibly make new acquaintances and on top of that you are giving your chess a healthy boost. The topics are generally ambitious, but the atmosphere leans more to the casual side. No matter whether you want to concentrate and work hard on your chess or rather prefer to relax and get entertained, you will find both in my seminars.
The schedule for open seminars is published on the front page.
