Chess.com's Weekly Study: July 30th 2016

DailyFun

Hello Chess.com!

Starting with 2016, we will be posting a Weekly Study, courtesy of Yochanan Afek, Grandmaster for composing endgame studies. These challenging positions are designed to stimulate (and improve upon!) your creativity, depth of calculation, pattern recognition and pure imagination.

M. Liburkin, 1940

Enjoy!

Thank you!

It's a study requiring study. What happens when the bK starts roaming the board instead of meekly squandering his queen?

I wondered the same thing and tried a few roamings. Black has several better ways to lose. Sometimes the bishops are exchanged and White gets to win a queen vs. b-pawn on the 7th rank ending. Sometimes the black bishop and pawn are lost and White wins with the right rook pawn. The longest Black can hold out (from the starting position) is mate in 26.

Do not overlook the towering role of Yochanan Afek in selecting the Weekly Study. You couldn't pick a more competent and knowledgeable person in the field of endgame studies. Not only is he well-known as a GM composer of subtle studies but also as an organizer of numerous events and activities. My best score ever I achieved in a solving tourney he set up in Wijk aan Zee. He is a great communicator and always available to assist others in the realization of their ideas. Yochanan is the real treasure of this forum.

It hasn't lied to me yet. I guess there's always a first time.

And he has 294 entries in HHdbV for studies composed from 1967 (at age 15) to 2015 (at age 63).
