Material and time Evaluating a position in tenns of material is easy. All you have to do is count: queen

=

9 points, rook

=

5 points, etc. Now that you have taken your chess skills to a higher level, you will find that this way of evaluating positions is too simplistic. It is also important to take into account the dimension of time not the time on your clock, but the time on the board.

Lead in development In the position on the left, White has a temporal advantage of three moves. White has already developed both his bishops and he has already castled.

Badly positioned pieces On the right, Black requires two moves to bring the knight on a5 back into play.

White not only has a slight lead in development, but he can also exploit the poor position of Black's knight. The knight cannot take part in the defence of the kingside. Many of White's pieces are aimed at Black's king. The appropriate course of action is therefore an attack on the king:

1. Qa4 (to the kingside with a gain of tempo) 1. b6 2. Qh4 h6 3. Bxh6 gxh6 4. Qxh6 Nb7 (there is no much else) s. NgS NcS 6. Bh7+ KhS 7. Bc2+ KgS S. Re3 and 9. Rg3. White has a clear •••

advantage on the kingside. The black knight was unable to join

the defences. The following three positions have been taken from a game between Leo Kerkhoff and Eddie Scholl. Kerkhoff cleverly exploits his lead in development while Scholl rather neglects to develop his pieces. The first diagram arises after 1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. BgS c6 S. Be2 Nbd7 6. NfJ Qc7 7.
