Orthodox Helpmates

Helpmate in 2 (duplex)

My first composed helpmate in orthodox chess received a 'Commendation' in the Tourney for Helpmates in 2 (duplex) (The Problemist April-June 1976, pp.37-8) for which it was composed.

"Duplex" means that there is one solution with Black moving first and White giving mate, as is usual in helpmates, and another solution with White moving first leading to a mate by Black.

Solution:Black 1.Bg3 Rg7 2.Bh2 Bd4
White 1.Rg7 Bd4 2.Rg8 Rh2

Comments: 4th Commend. "Ultimately the masked half-pin is being exploited. Who will show a complete half-pin in a duplex on both sides?" Shlomo Seider.

Helpmate in 2½ (2 ways)

Solution:1.Re6 N3d4 2.f4 Nd6 3.Re5
and 1.Bd3 Ne5 2.f3 Nd4 3.Be4

Comments: "Marvellous find; variation of self-blocks is neat, but what really makes the problem is the differentiation of WP moves" D. A. Smedley.

Modal change (i.e. interchange of orthogonal and diagonal aspects) is one of my favourite themes.

Helpmate in 3½

Solution:1.b4 Ra3 2.Kc1 Ra5 3.Kd2 Re5 4.c3

Comments: Unfortunately this problem was completely anticipated by Eugene Albert, Schach 1966.
It also appears as Problem 432A in Albert's Ideal Mate Chess Problems 1966.

This anticipation, and the one in the next composition, discouraged me from composing further orthodox helpmates, because of the difficulty of knowing what has been done.

Helpmate in 4

Solution:1.Bf1 Ra8 2.Bb5 Rxh8 3.Ka4 Rh1 4.Rb4 Ra1

Comments: "Rundlauf of considerable elegance" B. P. Barnes. "Flying fortress" R. Brain. Also quoted in lecture by C. G. Rains, Sep 1979 p.359.

Unfortunately anticipated by A. Havasi, Fairy Chess Review 1944 (BKd6, Rh3, Bh8, WKc2 Qe1, Ra1) showing the task with only 6 pieces but using BQ. Also anticipated by an earlier example by T. R. Dawson Bolton Football Field 15 Jun 1912, version (BKf5, Rf1, Rg4, Ba8, Pg3, WKb3, Rh1).

"Very good that all pieces move in both solutions" K. Valtonen.
