Belatedly seconded, <beenthere240>.
This game is conducted very logically by both players, and by simple, almost arithmetic attrition, Black wins precisely as he should.
As a test of his opponent's technique, this game after all being played in antiquity, White might have held on longer with, say, <26. Bd6 ...>, when the game might have continued, <26. ... Nge7 27. Rd1, f6 28. Bxe7 [28. e6?, Re3], Nxe7 29. Rd7, Kf7 30. Rxb7, Rc1+ 31. Kg2/f2, Rc2+ 32. Kf3/h3, Rxa2 33. exf6, Kxf6 > and Black has no worries.
In this line, Black can also play <26. ...Ne3> with comparable advantage. Also available is <26. ...Rc2>.
All lead to a winning advantage for Black, just not as fast as the line played, where White's pieces reach the same position after 28. Bd6 that they occupied after 26. Bd6 above, while Black has gotten in the useful ...Rc2 and ...h5.
In its entirety, this is just what <beenthere> said: a bust to the Halloween.
Enjoy your Samhain celebration, and don't forget that tomorrow is Dia de los Muertos: fittingly for White's gambit, the Day of the Dead.
