A A Troitzky - In Memoriam

Alexey Alexeyevich Troitzky (March 14, 1866 – August 14, 1942) is one of the main founders of modern study composition, defining its principles in 1910. He is the first one to solve the “2 Knights versus pawn” endgame back in 1906, inventing the Troitzky winning line in the process. Later on in 1924 he published his classic book “500 endgame studies”; some historians says he composed more than 1,000 studies. He was blessed with an extraordinary chess mind, composing unbelievable game like positions for anyone’s enjoyment. Unfortunately, he died of starvation in WWII during the siege of Leningrad in 1942; in the same time, all his papers and notebooks were destroyed. We are truly lucky his published books survived and could be enjoyed by latter generations.

It is hard to choose a favorite from the studies he published. His positions and solutions are so deep and rich in content, they really "Wow" you time and time again. One of them for my liking is this present one; white sacrifices its Rook 6 times in a row until black cannot refuse it anymore. Any capture leads to a decisive fork and in the end black has no choice. Hope you will enjoy it!

Snatching a victory

White has a very direct Rh7-h8# threat and black's most obvious defences are not satisfactory:
a) 1... Ke8 2. dxc4 ...
b) 1... Re2+ 2. Kxe2 Qe7+ 3. Qxe7+ Kxe7 4. dxc4 ...
Desperate times require desperate measures and black figures out a spectacular way to snatch the victory from the jaws of defeat. Hope you will enjoy replaying the winning combination!

Queens' mesmerizing windmill

We all know the Queen is a powerful piece. It is also very fascinating in what it can do in the most unexpected situations. Here 2 Queens get to work together and defeat 6 Rooks using a mesmerizing windmill. Why is this working with all these powerful pieces involved? The answer is so close to real life, it leaves you wondering: the weakest and most ignored participant - a pawn - proves to be the weakest link. "Good bye (black)!" as they used to say in that popular TV game... Enjoy the combination!

How good were you as a 6 years old?

Not sure about you dear reader, but at 6 years old I was just an amateur beginner. My mom would beat me at chess senseless with a few opening traps she knew and to this day she is the one opponent I have the most lopsided losing score against; of course that is a result of her retiring the minute I took it more seriously and learned all her tricks. Here I would like to show you what is needed today to stand a chance at succeeding in junior chess. The position comes from a Golden Knights B28 club game between 6 years old Ethan and 13 years old Coco; the game was postponed for a while and when played it ended that tournament. Enjoy the combination!
