💟 About Rashid Nezhmetdinov for his birthday ( Today, 15th December, 2018 ) , a Soviet International Master who was a great fighter with amazing victories against top Soviet players.

‼️ Rashid Nezhmetdinov was a fantastic soviet chess player. Great world chess players lauded him as: 👇👇

▪️ "Nobody sees combinations like Rashid Nezhmetdinov." Mikhail Botvinnik

▪️ "Nezhmetdinov is the greatest master of the initiative." Lev Polugaevsky

▪️ "His games reveal the beauty of chess and make you love in chess not so much the points and high placings, but the wonderful harmony and elegance of this particular world." Mikhail Tal

▪️ "Rashid Nezhmetdinov is a virtuoso of combinational chess." David Bronstein

⚛️ A Fantastic game by Nezhmetdinov which named "Nezly Done!" in chessgames.com site.
In this game Nezhmetdinov has sacrificed his queen in 12th move!!👇👇

🔸 Rashid Gibiatovich Nezhmetdinov vs Oleg L Chernikov
🔸 Chigorin Team Cup (1962), Rostov-on-Don URS
🔸 Sicilian Defense: Old Sicilian. Open (B32)

❗️ About this game CHESS.COM has written:

He really had a killer instinct, since probably no one else(even computer) would ever calculate such a beautiful move as 12.Qxf6 truly is. Fascinating is that it was played in an OTB game. After 11th black's move, Nezhmetdinov was thinking about 45 minutes, and people watching this game just couldn't understand what he was thinking about. They thought it was clear that white should move the queen to h6 or g3, and were incredibly shocked when they saw this sacrifice.

🔹It's also considered as one of 110 most fantastic moves ever played.
