Black threatens Bxd7 and Bxc1.

Much more interesting is the game, especially the interesting demolition combination starting with 17. Bxh7!

Black's decisive mistake is the not-so-obvious 19...Kh7?, which gives White the win after the game move 20. Nd7 +- (+1.87 @ 31 depth, Stockfish 8) or the computer recommendation 20. Ng4 +- (+3.25 @ 31 depth, Stockfish 8.)

Ironically, the mistake (19...Kh7?) from this 1916 game was repeated again in a strong Master game in V Mikenas vs Kashdan, 1931, where a draw was agreed to by White in the position after <19...Kh7?> in this game.

What Black missed in both games is that instead of 19...Kh7? the correct move here is 19...Kh8 ⩲ to = (+0.51 @ 34 depth, Stockfish 8) with drawing chances for Black.

Earlier, instead of 15...Nxc5 16. Bxf6! ⩲ (+0.54 @ 30 depth, Stockfish 8,) Black can keep it fully level with 15...Qxc5 = (0.00 @ 35 depth, Stockfish 8.)

P.S.: Plan to catch the news reports about the solar eclipse on TV today. It's a big event as it's the first total eclipse to pass over the entirety of the USA in a hundred years. I don't have an approved solar filter or viewer to safely view the sun, so I have no intention of looking at the sun (or even the partially obstructed sun) directly.

"Game has been merged with a duplicate, but unsure which score is correct. Can anyone confirm?"

Not a duplicate the exact same position was reached one move earlier here...

I went to Italy one year to see a total eclipse of the sun.

For those within the 70-mile wide area of the total eclipse, the danger would be (1) watching all or part of the sun before the moon completely obstructs it or (2) looking at even a small crescent of the sun after the moon passes over and the sun starts to emerge.

To quote from my MSN/US News link from my previous post <Staring at the sun without eye protection is like burning the back of your retina, the back layer of your eyeball. And you wouldn't even know you're doing it because the retina has no pain fibers. People who stare at the sun without protection would get a blind spot in their vision right away though they wouldn't know until hours later or the next day that the blind spot was still there.
