Interesting games:
In the first moment the game looks like a drawn.
The black pawn seem on a5, c5 and b6 in secured position
and the white pawn are somewhat backward on a3.

White plays as next move a4!
with the idea to place the Knight on c4
and bind the Queen to the black pawn (b6).
Mate in 5 moves



NxN! as the only forced move,

if QxS (the only useful move)
follows Th1h3,

the Queen must leave the third row (e.g. Qe2)
Qe2, Qa4+
Rxa4, Rxa4+
Kb1, Th1#
