CHESS by Philidor

No. 300

BLACK (8 men) C. MANSFIELD (Problemisr, March

1966)

WHITE to play and mate in two moves; solution next week. Solution to No. 299 (Marlar): R — Q 5, threat R — K 5. I ... K PxR; 2 P=Q. I...BPx R; 2RxP.x...BxR; 2 Q — B 4. K xR; 2 BxP. ... RxP;2QxB.a.— BxP; 2 Q — Kt 2. I•...KIXP;2KtX WHITE (13 men) R. K x P; a Q — B 4. Brilliant self-block problem

with four captures on each of the critical squares.

It always intrigues me to see how closely chess parallels the (other) arts, not only in the developments of new schools and styles but in the emotional reactions it draws. Petrosian's games produce in me the same mixture of reluctant admiration, stupefaction and a kind of depressed alarm at my own bafflement that a Simpson, Ionescu or Pinter play elicits; a nice old- fashioned game with P — K 4 on each side, Kts on B 3 and Bs on Kt 5 and B 4 gives me the same comfortable feeling of natural and familiar territory that one gets from, say, Shaw. Here is a game which I hope will produce in readers the same feeling of being at home as it does in me.

P- K 4 P- K 4

7 B- Kt 3 P- Q 3 All right, but 7 ... P- Q 4 is more

vigorous.

8 P- B3 B - R

9 P- Q3 P-KR3? This weakening of the King's side must be wrong when White still retains the option of Q side castling; Black should just play 9 ... Kt - Q 2 and if to Kt-Kt 3 then to ... Kt - B 3. ro P- K Re 4! . • . instantly revealing the weakness of

Black's move. If in reply so . B xP; then it R - K Kt z,
