Jon Speelman: Seeing the whole board (opens in new tab)

Jon Speelman returns to the importance of seeing the whole board when calculating, using a series of positions in which small changes far from the main action transform the evaluation. Examples include back-rank motifs, a double bishop sacrifice inspired by Emanuel Lasker v. Johann Bauer and an adjourned game involving Alexander Kotov and Glenn Lambert. The focus is on tactical awareness, pawn moves, quiet resources and the need to continue variations until the position becomes stable.
