With the Tasc Chess CD you can be busy for many years.
On the CD you will find the first 5 steps with lessons and exercises.   (totally more than 2600 puzzles - different ones than in the books).
The course is in 4 languages: English, German, French and Dutch.
At least one American chessplayer is impressed:
"Of course I was spoiled by my earlier exposure to the excellent training CD made by TASC called 'Chess Tutorial' later found out that this was a highly successful 5 step method pioneered by Rob Brunia and IM Cor van Wijgerden.    .........
I cannot give this CD enough praise, every beginning to intermediate player should own it, or at least be exposed    to its methodology."
