This Chess Move Destroyed 2 World Champions

[0:00]Did you know there's a chess opening so deadly that it defeated both Capablanca and Alakine? The same Gambit took down two different world champions. Meet Em Bobjabov, the only player in history to challenge both legends for the world title. He discovered something incredible while preparing for his 1929 championship match. In the Queen's Gambit declined, after Black plays the normal moves E6 and Knight F6, Bogljabov found a shocking sacrifice. On move seven, he throws his entire knight away with Knight takes F7. It looks like a complete blunder. Most players think they're winning material, but while they waste time calculating how to capture the knight, Boljabov's attack becomes unstoppable. The sacrifice exploits a hidden weakness in Black's kingside. Even world class defenders couldn't find the right defense. Boljabov used this secret weapon against Capablanca in 1928. Then he shocked Alakine himself with the same Gambit in their 1934 rematch. Two world champions, same deadly sacrifice. Sometimes the most dangerous moves are the ones that look impossible.
