L.A. Times Problem No. 89 by G. Chocolous, from the Two-Move Chess Problem. White mates in two.
FEN r6Q/7B/8/8/8/5p2/7B/R4K1k w - - 0 1
Key: B-B7/Bc7
Occasionally a dual may be cured by turning the board to change the direction of pawn moves. Give this problem a quarter turn to the right and the key B-KN6 permits only one mate after pawn move, whereas in original position after pawn move there are three mates—a triple.

David Janowski vs Jose Raul Capablanca New York (1924), New York, NY USA, rd 1, Mar-16 Queen's Gambit Declined: Orthodox Defense. Janowski Variation (D67) 1/2-1/2 https://www.chessgames.com/perl/chessgame?gid=1102094
4. Nc3 Be7(a) 10. h4(b) f6(c) 16. Bd1 Bb4(d) 18. bxc3 Nxf4(e) 20. Kh1(f) Qh3+ 1/2-1/2
Notes by Alekhine
(a) Of greater promise than this antiquated method seems to be P-B3 so as to meet 5. P-K3 with QN-Q2; 6. B-Q3, PxP; 7. BxBP, P-QN4; 8. B-Q3, P-QR3 followed by P-QB4.
(b) If this is not a new move (in these days one can hardly make such a claim for sooner or later some one will come forward and claim black on white that he used this move decades ago in some Class C tourney and hence claim parental recognition.) it has nevertheless been well forgotten. Doubtless it is more promising than 10. BxB, QxB; 11. Castles, etc.
(c) This weakening of the K3sq is not justified and causes embarrassment to black. Instead he should have held the position in abeyance while completing his development.
(d) In order to meet 17. N-K5 favorably with Q-B4, (the pin preventing N-K4.)
(e) Black now emerges from a somewhat precarious situation. White must accept the sacrifice or obtain no return for the lost pawn.
(f) Forced, since 20. KR2, QxBPch' 21. K-R, QxR; 22. B-B2, Q-R3; would lead to nothing.
