The Problemist, March 2006
Written by Michael McDowell   

The March Problemist featured a report on the Final of the 2005-2006 Winton Capital British Chess Solving Championship, the strongest Final in the history of the event, with three of the top four from the last World Championship participating. Jonathan Mestel retained the British title, while World Champion Piotr Murdzia from Poland won the event overall. Articles included “The Zabunov Theme” by Diyan Kostadinov, “Some problems by Gerry Anderson” by Jim Grevatt, “The Scope of the Miniature: Mate Transference and Friends” by Michael Lipton, and “Seven Millennium Problems”, in which Stephen Rothwell detailed seven unsolved tasks as a challenge to composers. Browsing in the library featured a 1932 collection of problems by Polish player-composer David PrzepiĆ³rka. The awards for Studies 2004-2005 and Helpmates in 2½ and 3 for 2004 were published.

In the Supplement John Rice discussed the fairy pieces camels, giraffes and zebras, and introduced a new fairy form called Super-Andernach.

Mate in 3

Set 1...Ra8 2.Re2+ Ke6 3.Bc5; 2...Kxd6 3.Qxc6
1...Rb8 2.Rd2+ Ke6 3.Sc5; 2...Kxd6 3.Qxc6
Key 1.d7! (>2.d8Q+ Ke6 3.Qd7)
1...Ra8 2.Rd2+ Kd6 3.Sc5; 2...Ke6 3.Qxc6
1...Rb8 2.Re2+ Kd6 3.Bc5; 2...Ke6 2.Qxc6

In the Zabunov theme the firing piece of a battery becomes the rear piece of a new battery. Robin Matthews' beautiful example shows a reciprocal change of continuations between set and post-key play. The mechanism is worthy of close study.

Selfmate in 2

1.Bd2 (>2.Qg2+ Bxg2)
1...Rb7 2.Qb1+ Rxb1
1...Rc6 2.Qc4+ Rxc4
1...Rd5 2.Qd3+ Rxd3
1...Sd5 2.Qxf4+ Sxf4
1...f3 2.Qe2+ fxe2

One of Stephen Rothwell's “Millennium Challenges”. A light and elegant setting in which five variations show the Dentist theme, where the black unpins are followed by checks which force the unpinning piece off the mating line. Amazingly, given the amount of material still available, no-one has succeeded in showing six such variations in a selfmate two-mover.

Mate in 6

A deep idea, which must be visualised in its entirety. White's plan is to lure the black bishop to d4, then follow up with c3 and cxd4, but first the bishop's potential escape routes must be blocked!

1.Qf8 (>2.Qb4/Qxa3+) 1...Sc5
2.Qd6 (>3.Qf4+ e3 4.Q or Bxe3+) 2...Re5
3.Be3+ dxe3
4.Qd4 Bxd4
If 2...Bc3 3.dxe4 (>4.Qf4+ etc.)
