Problem N1:
A: 1: GG 9m-9l 2: Fi 7c-7f If 3:SE 14kx14e then 4:B 14c-15b 3:FE 8nx16f 4:P 16ex16f 4:Fi 10n-11k The King has plenty of breathing space, pieces can move freely and the Demon is out.
B: 1:SE 14k-14h 2:HF 16fx14h 3:GG 9mx14h 4:VG 9d-3j 5:K 9p-9o 6:GG 8d-9d 7:GG 14h-9m 8:VG 3j-3g Wins at least a GG for a VG.
C: 1: BG 11m-10l 2: HF 16fx10l+ 3: Fi 10n-11mx!1 Black has taken a slight loss in material without really improving the position.
Score : A=5 B=0 C=3

Problem N2:
A: 18: Fi 10e-5jx!2 19: FK 8o-9n Gives a flight square and the Fi must retreat
B: 18: Fi 11f-15jx!1 19: Fi 7n-11j 20: Fi 10e-5jx!2 21: FK 8o-9n This way you get the Hawk and Eagle
C: 18: Fi 11f-11i double threat, if Fix14l is covered; 19: B 14n-15o, 20: Fi 11ix10lx!4 21: Fi 10nx10l 22: GG 8d-9d mate.
Score : A=1 B=3 C=5

Problem N3:
A: 8:VG 9dx4i 9:LH 9nx4i 10:Fi 10c-11f if 11:P 13l-13k 12:Fi 11f-11i 13:RG 10mx10d+ 14:LH 8cx10d 15:GG 9m-9n - Interesting game (if 16:Fi 7c-10e 17:HF 4m-4k)
B: 8:SE 3f-2g 9:VG 4i-1k The great general falls.
C: 8:P 8e-8f 9:VG 4i-2j 10:VG 9d-6f 11:Fi 7n-6k - Black stands better.
Score : A=5 B=0 C=4

A: 18:VG-15j 19:Fix15j 20:Fix12x!5 mate OR 19:Fi-15kx! 20:GGx15k 21:VG-2g 22:WBx2g 23:Fix2g does not threaten the king as it will be burnt on 7b first.
B: 18:Fix12mx!5 19:Chx12m 20:RGx7m+ 21:FEx7m 22:Fi-7d 23:VG-3h.
C: 18:Fix10lx!5 19:FE(orVG)x10l 20:VG-15j 21:Fi-14kx! - and will burn the GG next with one of the Fi's.
