Calculation Training

Calling all ambitious players who are up for improving their calculation skills! In Calculation Training - Sharpen Your Game! a total of 73 examples have been selected, the vast majority containing multiple questions, and more than 160 questions of varying difficulty. The course kicks off with some relatively simple tactics (max. 1-2 moves) featuring well-known tactical motifs discussed on earlier video courses of the Calculation Training series. But then the difficulty level increases! Short forcing variations must be calculated very precisely, and opponent's errors need to be refuted.
In ''Spot the Weakness'', it helps to first determine which specific point needs to be targeted before looking at concrete moves. In the sections ''Defend'' and ''Brainteasers'' you will need a bit more time coming to the right conclusion, as even some of the World's best players have failed to deliver! The material is based on recently played games, as well as unpublished games by the students of the author, so likely you will be as yet unfamiliar with most of the exercises. Thanks to the interactive format, the exercises are suitable for players of any level. Step by step, the viewer will be guided through all the examples, as advanced players are likely capable of visualising positions from afar, while newbies have the possibility to take a fresh look at every new question.
