Guy SOBRECASES

The last move of the wJK (white Joker
King) can’t be a Rook or Queen’s move because of the JKh7 auto-check.

So, it’s a Bishop’s move 0.JKg2-h1! preceded
by JKe4-(x)h7!! To patrol e4.



1.JKc2? JK×f3 2.JKa4 JKe2 3.f1=B+
JKe4 4.Bb5 JKc2+; but 5.g2! stop the check

2…JKd5!? 3.f1=B ??zz 4.Bb5 JKb3‡



1.JKf5!! JK×f3 2.JKh3 JKe2 tempo (2….??zz 3.f1=B ??zz 4. Bg2+ JKg4‡) 3.f1=B+ JKe4! (play as
a Pawn not a Bishop !) 4.Bg2 JKf5‡
