Huffington Post, 2010

Inspired by the work of Ladislav Prokes, Noam Elkies created a different windmill study by moving the black pawn from d7 to h5 and removing the pawn on g7 from the original work and spinning the queen in two directions:

1.f4+ Kg4 2.Qg3+ Kf5 3.Qg5+ Ke4 4.Qxe5+ Kf3 5.Qe3+ Kg4 6.Qg3+ Kf5 7.Qxd3+!
Preparing to spin the windmill the other way.

[After 7...Kxf4 White wins with 8.Qg3+ (Or 8.Qe3+ Kg4 9.Qg3+ Kf5 10.Qf3++- ) 8...Ke4 9.Qe3+ Kxd5 10.Qb3++- ; 7...Kf6 8.Qc3+ transposes to the main line two moves early.]
