Chessbase engines can search the 3 best move instead of only searching for the best move. They did it in the beginning of the game and probably they could search more deep by searching only for the best move. searching for 3 best moves instead of only the best move is about the same as being 2-3 times slower. Even if we do not assume diminishing return from being 2-3 times faster the demage for programs in this case is not more than 100 elo and if we consider also the fact that the programs did it only in the opening the demage is probably less than 50 elo so it will probably not change the reuslt of the match because the expected changed in the result is less than 0.25 point Uri
