German championships eleven times and was a world championship contender in
his best years. At the time that this game is played though he is 77 (!)
years old. This is the main reason why in a very complex position he

As it was pointed out in Chess Today, Uhlmann missed a win.

How could Uhlmann calculate that deep during the game? He did not have to. All he needed to do was to remember the following study:

The solution of the problem would be the proper equipment with a base of knowledge. You do not need to know every single endgame by heart. It is hardly possible (except perhaps for a genius like Ivanchuk) but more importantly it is not worth memorizing countless endgames which are very unlikely to happen.
On the other hand each player should owe an existence minimum of exact positions in every major endgame (pawns above all but also knight/bishop/rook/queen) endgames. This will help the players a chance to orientate in most of the situations, will suggest them which pieces to trade and which to keep and naturally will support the calculation.
Best of luck in building your own memory library!
