Crackers from Ukraine

Post by Glarean »

The problem chess scene in today's Ukraine is a very diverse and lively one, and its leading composers are internationally highly esteemed personalities.
Notable among them are Sergei Didukh (*1976), Mikhail Pastalaka (*1974), Sergiy Borodavkin (*1969), Vladislav Tarasiuk (*1968), Igor Yarmonov (*1967), Sergey-N Tkachenko (*1963), Eduard Eilazyan (*1956), Vladimir Ryabtsev (*1959), Alexander Stavrietsky (*1959), Michael Grushko (*1955), Valery Gorbunov (*1950) or even a Vladimir Samilo (*1946).

The following examples show how aesthetically pleasing and at the same time chesswise complex these active Ukrainian problem authors are able to compose. They are likely to be hard nuts to crack even for the so overpowering chess programs and cannot simply be overrun by the engines...

Alexander Stavrietsky - Mate in 12

Unless by 'engines' you mean those powering TANKS. :x

Seriously though, I find it hard to stomach how some (I won't name the chess website...it's NOT this one) are 'justifying' that invasion. One person there posted a link to a known disinformation website with various 'neo-Nazi' stuff directed toward the Ukranian President, who is...Jewish.

The problems...indeed hard. I just tried one and had to give up pretty quickly, too much chaos on the board for this human.
