A 7-year-old boy's finger was broken by a chess-playing robot during the Moscow Open chess tournament.

The boy, identified as "Christopher," moved the piece before the robot finished moving, causing it to grab his finger and snap it. The tournament noted that for safety purposes players must give the robots time to finish their moves.

"The boy is all right. They put a plaster cast on the finger to heal faster. Yes, there are certain safety rules and the child, apparently, violated them and, when he made a move, did not notice that he had to wait. This is an extremely rare case, the first I can recall," said the Vice President of the Chess Federation of Russia, Sergey Smagin, according to the Guardian.

The boy was able to finish the tournament with the cast on his finger, but his parents are reportedly contacting the local prosecutor’s office to press charges.

The video of the incident was first published by the Baza Telegram channel, which also released his name. Baza said he was among the 30 best chess players in Moscow in the under-nine age group category.

Sergey Lazarev, the president of the Moscow Chess Federation, acknowledged that the incident was concerning but that the chess federation “has nothing to do” with what the robot does.

"The robot broke the child's finger - this, of course, is bad. The robot was rented by us, it has been exhibited in many places, for a long time, with specialists. Apparently, the operators overlooked it. The child made a move, and after that we need to give time for the robot to answer, but the boy hurried, the robot grabbed him. We have nothing to do with the robot," Lazarev told Tass News, a local news agency.
