Only needs 14 captures.
Is this position legal?

Legal#The black pawn is missing and the structure allowd for it to be promoted and moved to a1. The white e1 pawn promoted to a dark-squared bishop. How? Well it captured both black knights and the black queen to get to the c-file to promte-the only open file for it to do so on-and then captured the a1 black rook to promote to a dark square bishop. It then moved out. Thus this position is legal.
No, the Russian’s position is illegal. Translate what I said to him.
