Qxg4 Qxg4 24. hxg4 Rad8 25. Nb3 Nxd3 26. Re2 b6 27. f3 Black’s compensation appears to be quite dubious, 侯逸凡 (Hóu Yìfán) – Naiditsch, 5th GRENKE Chess Classic, Baden-Baden 2018. 10. ...

Black has more than enough for the Pawn and the game may be well assessed as balanced.
18. Re2 Bxe3 19. fxe3? A horrible move, which has no other merit than that of keeping the extra Pawn at all costs — that is indeed too high a cost to pay. Most likely after 19. Rxe3 Rd2 20. Re2 Rfd8 21. Kf1 the game would have ended in a draw, but... that’s all another story. 19. ... Kf7! 20. Ba4 Ke7 21. h3 Bc4 22. Rc2 Rd3 23. Re1 Kd6 24. Bb3 Ba6 25. Rcc1 Ke5 26. Rcd1 Rfd8
27. Rxd3? After this, White ends up being inexorably zugzwanged. He had rather to seek salvation by returning the Pawn with 27. Rf1. 27. ... Bxd3−+ 28. Kf2 Rd6 29. Bd1 Bc4 30. b3 Rd2+ 31. Kg3 (31.
