17. Rxf5??
A miscalculation by 14-year-old Azeri player. It would have been better to choose one of the following lines:
A)17. g4
B)17. Nxd5 exd5 18. e6
17...exf5 18. Nxd5 Ngf6!
He has probably overlooked this move.

After this move, it became clear that Black's opening experiment was very successful and that he has a good game. All his minor pieces are well placed.
17.e5! Nd5 18.Bxd5! exd5 19.Ng2 Nc7 20.Nef4 Qd7 21.Ne3 Rfd8!
Now Black demonstrates that he does not want to protect d5.

An important method of developing the initiative is exchanging your opponent's best defensive pieces.
19.Nxd5
White should have played 19.Rxd1 Bxc3+! 20.bxc3 Qc7. Despite the fact that Black is better here, White is better off than the game.
19...Qxd5 20.Bxe7 Rfd8!
Black has to sacrifice the exchange to create threats. In such positions activity is more important than material.
21.Bxd8 Rxd8 22.Qxa5 Bxb2

▪️ Vienna 1873
🔰 The Vienna 1873 chess tournament was a side event of the world exhibition of 1873, the fifth since the first Great Exhibition in London in 1851.
🔰During the epidemic, the tournament took place in the rooms of the Wiener Schachgesellschaft from June 21 to August 29. The time limit was twenty moves per hour. It was a twelve player tournament. Each participant played every other for a match for two points with a maximum of three games. There were eleven rounds of match competitions. Every short match had to be ended within two days. If the overall score gave no winner (1:1,=1 or 0:0,=3), the result was drawn with a half point given to each player. Wilhelm Steinitz won the tournament after a play-off with Joseph Henry Blackburne (2–0). Almost everyone now conceded that Steinitz was the strongest chess player in the world.
🔰Emperor Franz Josef I of Austria, Baron Albert Salomon von Rothschild and Baron Ignaz von Kolisch contributed large sums to the prize fund. The prizes winners were: Steinitz 10 points & winner of playoff (1000 guldens (F) & 200 golden ducats), Blackburne 10 points (600 F), Anderssen 8½ points (300 F), Rosenthal 7½ points (200 F). Scores of the other players were: Paulsen and Bird 6½, Fleissig and Meitner 3½, Heral, Schwarz and Gelbfuhs 3, Pitschel 1.
