"An astounding amount of play in a fairly static position. The zugzwangs continue even once the white pawns start moving. Positions involving corresponding squares for pieces other than kings are always interesting. And yet: this is not a solvers' study - it is fairly technical and not easy to understand and is really a long, complex positional draw." (judges Jonathan Mestel and Allain Pallier)

"A long and complex study in which White struggles to unpin his rook to deliver mate on the back rank. The highlight is the manoeuver of the rook from a7 to a1, g1 and g7, by which White reverses the arrangement of rooks along the seventh rank. However, the study lacks a central point and the end comes more or less by chance when, finally, white manages to use his knight to shield his king" (judge John Nunn)Watch this study on a dynamic board!
