  Sergash: 21.Nc4!

Threat : Nd6+ winning the black queen.

20...Qe8?!

20...Kc7 21.Nc4! (less good is the evident 21.Bxd7 Rd8 22.Nc4! Rxd7 but White wins with almost any move now!) Ne5 22.Qg3! Qf6 23.Nxe5! Qxe6 24.Rfd1 etc.

  Sergash: 20.Be6

20.Nc4! h5 21.Qe6! Qf6 22.Rad1! and this game will soon be over...

19.Bxh8?!

Did Polerio want to give a chance to his opponent? Did he promise that he would beat him without taking his queen? Maybe his opponent said something like "That's it, you take my queen and I am done because of it now!"

And Poleria could have said that he was done anyway and to prove it he would not take his queen?

Of course, the best move is here is 19.Bxe5 and then White mates in 13 moves or less. But the game move also wins easily.

  Sergash: 17...Kc8??

The losing move!

The only move here is 17...Qxf6 18.Qxg4 Qxf7 19.Rad1! Kc7! 20.Qg3+! Kc8 21.b3! Nd7 = White has full compensation for the missing piece buth no one has an advantage, it seems.

17.Bxf6??

Destroys any advantage White had!

17.Nf3+ (or 17.Nc4+ which transposes) Kc7 18.Nxe5! Bxd1 19.Bxf6 wins

  Sergash: 16...Qxe5??

Capturing the white queen is the only playable move :

16...Bxd1 17.Raxd1! b5! 18.Ndc4+! Kc8! 19.Nd6+! Kc7 20.Nf3 and despite the material imbalance, the Houdini software considers the chances to be balanced.

  Sergash: 16.Nxe5??

For White, the win goes through a queen sacrifice :

16.Nc4+! Nbd7! 17.Nfxe5! Bxd1 18.Raxd1 and White is winning.

  Sergash: 15...Kd8??

As Jonathan Sarfati put it, the bishop sacrifice seems to be a kind of bluff.

15...Kxf7 16.Bh6! Re8

  Sergash: 15.Bxf7??

Why put your game at risk when you have a winning advantage? As Honza Cervenka said above :

15.Nc4! 0-0 16.Ncxe5! Be6 17.Qc1!

  Sergash: 13...g6??

A useless weakening!

A- 13...Nbd7 14.Nc4! Bxf3 (14...Be6 15.Nh4! exd4! 16.Re1 ) 15.gxf3! 0-0-0 (15...h6 16.Bh4 0-0-0 17.Ne3 ) 16.Ne3 (16.b4!? )

B- 13...0-0 14.h3 Bh5 15.Qb3! Qc7 16.Bxf6! gxf6

  Sergash: 13.Qd1?

Why bring the queen back to d1 on the next move avfter it left that square?

13.Nc4!0-0 14.Nxd6! Qxd6 15.dxe5 Qc7 16.exf6 gxf6 17.Bh6! Nd7

  Sergash: 11...Bg4?!

Despite the appearances, this move is not good.

11...Bc7

  Sergash: Houdini chess software : 10...h6! 11.Bh4 (11.Bxf6 Qxf6 12.a5 (12.Nc4!? Nd7 ) Ba7 13.Qa4+ Nd7 ) 0-0

  Sergash: 9...Nb8 is dubious.

At the Athens Acropolis Open of 2006, in the game Fragiadakis (2223) vs Kakadelis (2157), Black played 9...Bd7; the game ended as a draw.

Also, Houdini program favors 9...0-0 10.Bxc6 bxc6 = /

  Sergash: 7.Bg5 is somewhat inferior and was probably played to induce 7...f6?!

More commendable are :

A- 7.a4 a6 8.Be2!?N = /

B- 7.d5 Nb8 8.a4 a6 9.Na3 = / Bednarczuk vs Chabrzyk, 1995 Polland Under 18 Championship, Group B, in Olkusz, won by White

C- 7.Ng5 Nd8! 8.a4 a6 9.d5 = /

D- Note that the most played move, here, is a defensive one : 7.h3

  Sergash: 5.0-0

5.d4 as seen in the game Scovara vs Paolo Boï, is possibly stronger.

  offramp: Well done, <Sergash>!

One down, 783,524 to go!

  tpstar: The only database game by Lorenzo with fine opening play but then things fall apart pretty quickly. Most likely he was a wealthy patron to Polerio where White wanted to win without outright humiliation. How else to explain 19. Bxh8 over 19. Bxe5.

Cute Knight Fork tactic near the end.

<Well done, <Sergash>!> Indeed.

Apr-07-17  Yigor: The opening is more or less well-played. The main line 4...Nf6 is better than the Closed Giuoco Piano 4...Qe7. Also 9. d5 is better than 9. Bd5.
Oct-08-18  Blue Morphine: Even though they are players from ancient time, compared to other players from their time, I must say it was a terrible play from both sides *sigh*

  Ziryab: The game score is incorrect, according to Peter J. Monté, <The Classical Era of Modern Chess> (McFarland 2014), pp. 247, 458.

Moves 13-16 should be 13. dxe5 dxe5 14. Nxe5 Qxe5 15. Qxf7+ Kd8 16. Qxg7 Qe8. Correcting the game score eliminates the most absurd moves in the game.

  phenstyle: I'm giving Polerio at least 2100 elo+ for this game, very nice strategy and super precise mate at the end. Stronger than some 2100 elo I've played in real life.

My previous comment a few years back might have been irrelevant, seems this game changed?
