The absence of the f6-knight (the best defenderof the king) can have serious consequenceseven if the king seems to be safe. Here, thewhite rook can enter through the f-file to drawone of the black pieces to a mined square.

Black's king seems enough protected, but after acloser look we can notice that the blackdefending pieces effectively suffocate him.Therefore, White draws the black king out into amate net.

exercise 7

(Diagram)

White's king is unprotected, while a lot of Blackpieces are orientated toward him. However, itseems that there is no entrance. Usually,something must exist in these situations and theplayer should be very careful at every momonet(move) during the practical game in order to notloose the occasion.In exercises, the student knows that something

should exist. During the game, the player shouldalways look with a fresh eye to the position andfind such simple combinations.

The black king can be saved by only a move: thequeen sacrifice. After this, the white king will bein an unproper position that the advanced blackpawns can exploit.This exercise is instructive if you will need tocalculate this situation in a practical game withmore moves in advance and to foresee thisdefensive queen sacrifice.

In absence of the knight on f6, the f-pawn is avery good defende of the king's position. Morethan protecting the b1-h7 diagonal, the f7-f5advance creates space for the black pieces.
