Re1!!) with an additional variety of other tactical Zwischenzugs on both back ranks. The battle to secure promotion ends up eventually in favour of White who manages a narrow victory thanks to his extra knight. This knight is promoted after both initial white knights have been given away and then plays an active role in the ensuing endgame. This makes the study also a remarkable contribution to the Phoenix theme. A truly impressive artistic and thematic achievement!} 1-0

A logical study with a paradoxical foresight effect that becomes apparent at the end of the main line compared with the thematic try and described in detail with the second move of the solution. The reciprocal zugzwang position is a surprising discovery while the knight sacrificial switchback to g8 is an impressive introduction to the main scene of events.} 1-0

A very interesting interpretation of a reciprocal zugzwang built up on the ruins of an earlier unsound joint study by Kaminer and Rossolimo.
