Theme Palaestra

We are happy to present No. 1168, an original by F. Gamage, a famous composer of the "Good Companion" days who returns to his metier after a number of years of inactivity, and who is again winning prizes in international contests. Nos. 1186 and 1187, the latter by W. B. Rice, are offered as reminiscences of that historic period.

The five problems, Nos. 1169, 1170, 1171, 1172 and 1175, are versatile studies in black self-interference, each with a special thematic feature. No. 1169 stresses the en passant play, No. 1170 the line shut-off defense, No. 1171 mates in the line of pin. No. 1172 defenses pinning White, and No. 1175 defenses unpinning White.

With No. 1173 we welcome Will C. Dod of Miami, Florida, who was for some time a member of the band of composers contributing to the former Cincinnati ¡inquirer column edited by Dr. F. G. Keeney who, by the way, regales us with two cute Merediths, Nos. 1174 and 1176!

No. 1179 is an interesting example of V. L. Eaton's successive check—successive interference idea illustrated in Mr. Raton's essay in the April and May issues of The Chess Review.

Nos. 1188, 1189, and 1190 are illustrations of the Anti-Rupp, so designated because its progression is the reverse of the Rupp. Here the key simultaneously unpins both a black and white piece, and a black defense simultaneously repins these pieces. Thus in No. 1189, 1 . . • Be4 repins the Queen (c3) and the black Bishop, allowing mate by 2 Qg2,

The remaining problems, Nos. 1191-1194, are examples of the Seeberger, so named after J. Seeberger, whose problem (No. 1194) con-tained amazing strategy for its time. In this theme a black piece is decoyed to a certain square, whereupon a new White threat forces a second black piece to so move that the decoyed piece is immobilized by obstruction. A waiting position results in which White mates by zugzicang.

For instance, in No. 1191, 1 Qd2 threatens 2 Qf2ch. Black defends by 1 ... BxS. Now 2 Qelch, Kg2; immobilizing the B by obstruction, enables the waiting move 3 Kf4, and mate follows.
