In the study to win for the first time presented a combination of Novotny in the form of mutual zugzwang. An attempt to destroy it leads to the immuring of the black rook and bishop, which took their places in the game, but eventually became a hindrance to save the king. This allows white small forces to turn off from the fight all the opponent's pieces, again putting them in the position of mutual zugzwang, and then strike the decisive blow.} 1-0
