The Scotch Game, or Scotch Opening, is a chess opening that begins with the moves:
Ercole del Rio, in his 1750 treatise Sopra il giuoco degli Scacchi, Osservazioni pratiche d’anonimo Autore Modenese ("On the game of Chess, practical Observations by an anonymous Modenese Author"), was the first author to mention what is now called the Scotch Game. The opening received its name from a correspondence match in 1824 between Edinburgh and London. Popular in the 19th century, by 1900 the Scotch had lost favour among top players because it was thought to release the central tension too early and allow Black to equalise without difficulty. More recently, grandmasters Garry Kasparov and Jan Timman helped to re-popularize the Scotch when they used it as a surprise weapon to avoid the well-analysed Ruy Lopez.
White aims to dominate the centre by exchanging his d-pawn for Black's e-pawn. Black usually plays 3...exd4, as he has no good way to maintain his pawn on e5 (this same position can be reached by transposition from the Centre Game 1.e4 e5 2.d4 exd4 3.Nf3 Nc6). After 3...d6, White is better after 4.dxe5 dxe5 5.Qxd8+ Kxd8 6.Bc4, or he may simply play 4.Bb5, when 4...exd4 5.Nxd4 Bd7 transposes to the Steinitz Defense in the Ruy Lopez.
3...Nxd4 is possible, though rarely played today by strong players. It was popular in the 19th century, and receives five columns of analysis in Freeborough and Ranken's opening manual Chess Openings Ancient and Modern (3rd ed. 1896 p. 53). It is often described today as a strategic error, since after 4.Nxd4 exd4 5.Qxd4 (5.Bc4 is the Napoleon Gambit) White's queen stands on a central square, and is not developed too early since it cannot be chased away very effectively (5...c5? is a seriously weakening move that blocks Black's king's bishop). Nonetheless, the Encyclopaedia of Chess Openings (volume 3, 3rd edition 1997, p. 251 n.28, referring to p. 252 line 1) concludes that Black equalises with 5...Ne7 6.Bc4 Nc6 7.Qd5 Qf6 8.0-0 Ne5 9.Be2 c6 10.Qb3 Ng6 11.f4 Bc5+ 12.Kh1 d6. Similarly, Harald Keilhack concludes in Knight on the Left: 1.Nc3 (p. 21) that although ...Nxd4 is a "non-line" these days, if Black continues perfectly it is not clear that White gets even a small advantage. Keilhack analyses 5.Qxd4 d6 6.Nc3 Nf6 7.Bc4 Be7 8.0-0 0-0 9.Bg5 c6 10.a4 Qa5 11.Bh4 and now after 11...Qe5 or 11...Be6, "White has at most this indescribable nothingness which is the advantage of the first move." (Id. p. 25) The Encyclopaedia of Chess Openings also concludes that Black equalises after the alternative 4.Nxe5 Ne6 5.Bc4 Nf6 6.Nc3 Be7 7.0-0 0-0 8.Be3 d6 8.Nd3 Nxe4 10.Nxe4 d5 (p. 251 n.28).
