The Konstantinopolsky Opening is a rarely played chess opening that begins with the moves:
1. e4 e5
2. Nf3 Nc6
The opening was introduced in the game Alexander Konstantinopolsky versus Viacheslav Ragozin, Moscow, 1956.
The Konstantinopolsky Opening is rarely seen at the top levels of chess, although some grandmasters such as Savielly Tartakower (who played many unusual openings) have experimented with it. Black is considered to achieve an easy game with the natural and strong 3...Nf6 4.d3 d5.
