The following position is a very quiet position. There is nothing spectacular to find.
White has a slight grip on the position. But how can he make a move which squeezes Black just slightly more?
These are the sorts of moves which are very difficult for amateur players to spot. What move would Black like to play to ease his position slightly, and how can we as White stop it?
The only clue is that we should look at the worst placed pieces for each side.
If you find the move that Karpov as White played in this position, consider yourself to have a fine feeling for so-called ‘simple’ positional play.
The solution to last Monday’s problem was that Black squelches his opponents counterplay by playing Qc6.
The main variation is 1…Qc6 2 Qb5 Qxb5 3 cxb5 Kxb3 4 e4 Kxa4 5 e5 Kxb5 and wins.
Here is this week’s problem. White to move.
