With great delay I publish the award of the tournament Danka Petkova 100 MT2020-2021, due to my long illness after a very unsuccessful and dangerous vaccination against Covid. I apologize to everyone who waited for this material. Many thanks to the participants in the tournament, to the winners – world-famous masters, as well as to the readers who will look with interest at the tournament problems!
Be Valium healthy, cheerful and happy in the New 2022
Yours: Petko Petkov
