3rd Prize, 1st FIDE World Cup, 2010
Mate in 3
A problem which illustrates a pleasing visual theme.
1.Bf4 threatens 2.exd4+ Kxd4 3.Be3 and Black defends by moving the rook. After 1...Rd5 2.Re6 exploits the selfblock to threaten two mates 3.Rc6 and 3.Sa6, leaving Black the two defences 2...Bxe6 3.Sxe6 and 2...Rd6 3.Bxd6 (not 2.Rxe4? Re5!). After 1...Rd6 White again exploits the selfblock with 2.Re5+ Rd5 3.Rxd5. After 1...Rxd7 2.Rxe4 threatens 3.Rxc4, leaving 2...Bxe4 or Be6 3.S(x)e6 and 2...Rd4 3.exd4 (not 2.Re6? Rf6!). As the black rook ascends, so the white rook descends. Very striking.
