In this chess lesson we are going to combine some of the knowledge of the key squares, the square rule and the square rule for two separated pawns.
First have look at the diagram on the left site.

It’s a draw. Can you see why?

And do you see that the game is won by White if the black pawns are removed from the board?

Both White as well as Black didn’t have other options.

The next lesson is about the usefulness of a chess database.
