Judge Michel Caillaud: Composer succeeds in making Schnoebelen promotion less obvious, thanks to using 2 phases with 2 switchbacks as motivation. The need of a black tempo is the trick that allows differentiation of the phases (and the Schnoebelen Rook becomes an "anti-Schnoebelen" Rook!). Well done.
Sobrecases: Specific try play:

Judge Michel Caillaud: Additional condition allows a respectable length (not far from being a record for a C+ SPG tested by Popeye!) but also makes things easy. Game flow is nice but the trick of oscillating wRa1 is known (MC, 3rd Prize, D. Innocenti-44, 2002) and Immun condition easily helps progression of the play by blocking black Pawns.
