“Timman-70” Composition Tourney

In December, on the 14th to be specific, Dutch grandmaster Jan Timman turns seventy. He was one of the world’s leading players from the late 1970s to the early 1990s. He is also a prolific study composer. So it is appropriate that a Study Composition Tourney is being staged in his honour. Awards will be distributed on his birthday. For this announcement Jan has selected five of his favourite studies, composed by him, for you to solve.
