History Does not Repeat itself–Two Grischuk Endgames

A curious mistake that Mark Dvoretsky would have included into his book – happened in the following game, where White voluntarily exchanged into a hopeless pawn endgame:

Robson, R. - Grischuk, A.
42nd Olympiad 2016   2016.09.10 , C67

1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. O-O Nxe4 5. Re1 Nd6 6. Nxe5 Be7 7. Bf1 Nxe5 8. Rxe5 O-O 9. Nc3 Ne8 10. Nd5 Bd6 11. Re1 c6 12. Ne3 Bc7 13. Nf5 d5 14. Ne7+ Kh8 15. Nxc8 Rxc8 16. g3 Qf6 17. Bh3 Rd8 18. d4 Nd6 19. Bf4 Bb8 20. Be5 Qh6 21. Bg2 Nc4 22. Bxb8 Rxb8 23. b3 Nd6 24. Qd3 Qg6 25. Qd2 Rfe8 26. Re5 f6 27. Rxe8+ Rxe8 28. Qb4 f5 29. Re1 Rxe1+ 30. Qxe1 Qf6 31. Qe3 g5 32. f4 h6 33. a4 a5 34. Kf1 Ne4 35. c4 Kg7 36. c5 gxf4 37. gxf4 Qh4

38. Bxe4?
( 38. Bh3!? )
38. ... fxe4 39. Qf2?!
The position is objectively lost, but trading queens makes things too easy for Black.
39. ... Qxf2+ 40. Kxf2 Kf6 41. Kg3 Kf5 42. h3

42. ... h5 43. h4 e3 44. Kf3 e2 45. Kxe2 Kxf4 46. Kd3 Kg4

0-1
Interestingly, it was pointed out to me that Grischuk had lost a pawn endgame that was a complete mirror of this position only three years earlier:

Le Quang Liem - Grischuk, Alexander
   2013 , D87

1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 c5 8. Ne2 Nc6 9. Be3 O-O 10. O-O b6 11. Qd2 Bb7 12. Rfd1 Rc8 13. Rac1 e6 14. Bh6 cxd4 15. cxd4 Qh4 16. Bxg7 Kxg7 17. Qe3 Rfd8 18. h3 Qe7 19. Bb5 Qb4 20. Rb1 Qe7 21. Nf4 Nb4 22. d5 Nc2 23. Qg3 e5 24. Ne2 Na3 25. Rb3 Nxb5 26. Rxb5 Ba6 27. Rb2 Bxe2 28. Rxe2 Qd6 29. Qd3 Rc5 30. Rc2 Rdc8 31. Rdc1 Kf8 32. Qa3 Qe7 33.

The protected passed pawn decides matters as Black is unable to defend c5 pawn in the long run and is falling into Zugzwang.
42. ... h6 43. Kc4 a6 44. a3

1-0
