The '''Durkin Opening''', also known as the '''Durkin Attack''' or the '''Sodium Attack''' is a rarely-played chess opening that consists of the following move: : 1. Na3
The Durkin Opening is named for Robert T. Durkin (1923–2014) of New Jersey. The name "Sodium Attack" comes from the algebraic notation 1.Na3, as ''Na'' is the chemical symbol for the element sodium. Similarly, the Amar Opening (1.Nh3) is sometimes referred to as the "Ammonia Opening". White may follow up by playing c4,{{sfn|Kasparov|Keene|1982|p=3}} e.g. 1...d5 2.c4 dxc4 3.Nxc4. {{AN chess|pos=toc}}
==Assessment== This development of the {{chessgloss|queen's knight}} does little to utilize White's advantage of the first move. On a3, the knight does not control {{chessgloss|central}} squares, and White would have to move this knight again (e.g., to c2 or c4) for it to follow common opening principles, such as controlling the center. In addition, the knight on a3 runs the risk of being captured by black's dark squared bishop on f8, which could cause doubled pawns in some positions, a weakness for white, especially in the endgame. Angus Dunnington suggests that combining this move with a gradual central expansion should give White a reasonable position.{{sfn|Dunnington|2000|p=139}}
