This week's lesson is not particularly complicated for young players who look at the board carefully. However, too many look at threats against pieces without looking at control of squares.
White to move
White can restore the material balance with Rxb7. What would be the consequences of this move?
This position is from the game Westernin, H -- Ivkov, B Palma de Mallorca 1968.
In the game, White played 41.Raf1, and after 41...R4c7, White resigned.
