Fraternal Twin

Yesterday's post,  "Special Delivery From Russia", featured a game between Philidor 1792 and Endeavornick, where, at the end, I suggested that Black might have played on, to investigate the drawing possibilities of a Bishops-of-opposite-colors endgame. 


Interestingly enough, the following position, with Philidor 1792 as White to move, is from another game between the two same opponents, although I do not know if it was played earlier or later.

Here, too, White's advantage is an isolated c-pawn.


The game should be drawn with proper play.


Then, again, the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) should be won for Black with proper play, too.


51.Bh2 Kc6 52.Kd4 Bf5


Unthinkable. Clearly, time must have been very, very short.


53.Ke5


Ditto. Instead, 53.g8/Q leads to a forced mate.


However, here either Black resigned or Black lost on time, before he could level the game with 53...Bh7.
