Another endgame composition from Alan Tomalty(CAN) posted originally on the Chesstalk Message Board

Some words from Alan
‘I retired from government life and have been a chess teacher for the last 5 years both in elementary French and English schools as well as personal one-on-one tutoring. I have recently developed an advanced chess course for players up to master level that has 331 strategical and 434 tactical chess positions ordered by difficulty. All have been checked by Houdini and are clearly the best moves in the position. The strategical positions cover every known concept of strategy and the tactical positions cover all known tactical motifs.’
