I make also chess problems.
At the photo you see me in an Apeldoorn workshop with the late Cornelis Slagmolen (95), the oldest problem composer in the world at the time.
See also an article I wrote for Chess Today about problem composer dr. Milan Vukcevich.
See the site of Schwalbe for diagrams and solutions of 64 problems I composed.
65 of my problems and studies may be found also on this database: www.yacpdb.org
Fill in my name and you will receive 13 pages with my compositions.
By clicking on the problem number the solution shows up.
