Hello, Dear chess friends,
In the last issue of Endgame Series, we explained the importance of limiting the mobility of your opponent's pieces in endgames. In this issue, we will look at the flip-side of this topic; namely, the instances when conceding mobility to your opponent plays a decisive role in the game. The examples you will see often contain a "human" element; in other words, one or both of the players will make a mistake in the assessment of the activity of opponent's piece(s). You will realize that this is a moot point even for strong players as virtually all games I am about to show are from grandmaster practice. Without any further ado, let us look at the first example in which top GM Caruana made a serious mistake by taking a "poisoned" pawn in the endgame, allowing his opponent Aronian to activate his king with a decisive effect.
