The game of today is from a team match called ♔ Chess Without Limits ♔ vs RED STONES. It was played between Limitless Chess and RED STONES. I played board 8 in this match for Limitless Chess. Our team did change its name during this match and it was indeed called Chess Without Limits when the match started. Our team won the match, which was played on 16 boards, 23,5 - 8,5. This match started October 15th 2014 and finished on April 1st 2015. I have added one mate in one, two mate in twos, one mate in three and one mate in six today.
