Chess Opening Theory/1. Nf3/1...d5

=1.Nf3 Opening=

1...d5
Black stakes a claim to the center. White has many options now and as so often with 1.Nf3 many transpositions. 2. g3, 2. d4, 2. c4 (Réti), 2. d3, 2. b3, 2. e3, and even 2. b4!? are sensible moves.

White can also try the Tennison Gambit with 2. e4?!, usually reached with 1. e4 d5 2. Nf3?!, but it's considered dubious with best play.

Statistics
33% white wins, 45% draws, 23% black wins, for an overall score of 55.5% for white.
