Lasker and Reichhelm. The Ultimate Example of corresponding squares!

Hello Viewers!

I am sorry for not writing for a few days. I was busy in a tournament and a technical issue when upgrading to ChessBase 17. I installed it yesterday, and so this is my first blog post after I installed ChessBase 17!

One of the best endgame studies composed on corresponding squares was composed by Emanuel Lasker and Gustavus Charles Reichhelm in 1901. It is described in the treatise L'opposition et cases conjuguées sont réconciliées [Opposition And Sister Squares are Reconciled] by Vitaly Halberstadt and Marcel Duchamp.

Try to solve it yourself! If you actually solved it, please comment! The following is a list of corresponding squares and the Wikipedia illustration of this long list.

Key Squares:
b5, g5, h5.
Corresponding Squares:
0] h3 and f6
1] c4 and b6
2] b1, b3, d3, d1 and c7
3] a2, c3, c1 and b7
4] b2, d2 and a8, c8
5] a3, c2 and b8
6] h4 and g6, h6
7] e3, e2, e1 and d8, d7
8] f3, f2, f1 and e7
9] g3 and f7, h7

As you just read, it is too long to be read. So I offer a simple diagram taken from Wikipedia:

Now that's easy to understand! Now I offer the same position in puzzle form! You can easily solve it by just looking at the above screenshot and choosing the correct square!

Hope you liked it and were able to solve the position! At first glance it looks weird, but with the knowledge of existing corresponding squares, you can easily solve it!

Thanks for reading everyone! I am looking forward to publishing my next blog soon!
