Scotch Game

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.

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.

In the 20th century grandmasters Garry Kasparov and Jan Timman helped to re-popularise the Scotch when they used it as a surprise weapon to avoid the well-analysed Ruy Lopez.

Black usually plays 3...exd4, as they have no good way of maintaining their 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 the usual 3...exd4, White can respond with the main line 4.Nxd4 or can play a gambit by offering Black one or two pawns in exchange for rapid development.

On 5.Be3 play almost always continues 5...Qf6 6.c3 Nge7 7.Bc4 (as proposed by IM Gary Lane in Winning with the Scotch; several seventh move alternatives for White are possible here, 7.g3 for example) 7...Ne5 seems Black's strongest reply.

Where these main lines end, the first real opening decisions are made, which are too specific for this overview.

As of 2005, White's most successful line has been 5.Nc3 Bb4 6.Be2 Qxe4 7.Nb5 Bxc3+ 8.bxc3 Kd8 9.0-0, from which Black's awkwardly placed king has generally proven more significant than the extra pawn.

White sacrifices one or two pawns in return for a lead in development, and typically follows up by putting pressure on f7 with Bc4, Qb3 and sometimes Ng5, while Nc3–d5 is another common motif.

The gambit has been played by Ljubomir Ljubojević, David Bronstein, Frank Marshall, and Jonathan Penrose.

If Black avoids steering for Capablanca's ending, e.g. with 6...Nf6 or 7...0-0-0 in the above lines, then White obtains good piece play in return for the isolated d-pawn.

Thus both John Watson and USCF master Mark Morss recommend 7...Bxc3+, in order to meet 8.Qxc3 with 8...Qf6!

Alternatively, White can transpose into the Danish by offering a second pawn with 5.Bc4 cxb2 6.Bxb2, an approach which John Emms considers far more dangerous for Black.
