Figure 2.3.3.2[White to move]

Almost the same. White has a check with his bishop in Bxd5. The move also attacks the loose rook at a2. The d5 pawn is protected by the knight at b6, but the knight can be captured with RxN, a7xR, leaving the forking square loose. White plays 2. Bxd5+, Kh8, and then 3. BxR. That is how the position comes apart under interrogation about its targets, but notice as well that visually it is almost identical to the previous one; the only difference is that a Black pawn lies between the king and rook. It is important not to let an obstruction like that prevent you from seeing that the king and rook are on the same diagonal. Look through the pawn as you trace the lines on the board with your eyes.
