The solution to last Monday’s problem is that White can get a big advantage by playing 1. Qb5! This is much better than 1. Qxb6 which also leads to an advantage.
After 1. Qb5 the Black King is trapped in the centre, with all of White’s pieces attacking it.
This week’s problem is about how to effect a breakthrough.
With good positional play, we can increase the pressure on our opponent’s position. But sometimes it can be hard to breakthrough.
One method is zugzwang where we force our opponent to move away one his key pieces.
Another method is to sacrifice , which will also force our opponent to move something he doesn’t want to move.
In this week’s problem, it is obvious that White has a good position, but how can he make a breakthrough?
