Wade Defense

The Wade Defense arises after 1. d4 d6 2. Nf3 Bg4. It can also be reached by the move order 1. Nf3 d6 2. d4 Bg4. It is named after Bob Wade, the New Zealand-born British International Master who used it for more than three decades. Yrjölä and Tella's repertoire book calls it the Hodgson Variation instead, honoring the grandmaster most closely tied to its development.

Black develops the light-squared bishop before any ...e6 or ...e5 can shut it in, and aims it at the knight on f3, the piece that guards e5 and supports d4. The usual follow-up is ...Nd7 and ...e5, contesting the center with pawns. Black is also ready to give up the bishop with ...Bxf3, accepting the loss of the bishop pair to blunt White's central control, and often combines this with a kingside fianchetto. White, for the moment, keeps the choice of pawn structure, and can put the question to the bishop with h3.

The most common reply is 3. e3, a modest setup that keeps the position compact. With 3. c4 White gains queenside space. One line is 3. c4 Nd7 4. Nc3 e5 5. e3 c6 6. h3 Bh5, where Black keeps the bishop and builds a ...e5 and ...c6 center. Another is 3. c4 Nd7 4. e4 Bxf3 5. Qxf3 g6 6. Nc3 Bg7, in which Black has already surrendered the light-squared bishop and plays against White's dark squares. In Topalov–Adams, Dortmund 1996, Black later traded the other bishop too with ...Bxc3+ to break up White's queenside pawns. Engines prefer 3. e4, which takes the full center at once, along with 3. Nc3 and 3. c4.

The Wade Defense is a sideline, well down the list of named openings by frequency. In the database White scores 51% against Black's 44%, and draws are unusually rare, so games tend to be decisive. The engine gives White a clear edge, which reflects the space Black concedes rather than any concrete refutation. Rudolf Spielmann played the line in 1938, and Stein and Kavalek used it in the 1960s. Julian Hodgson later popularized it, and Tony Miles, Michael Adams, Vlastimil Jansa and Hickl added to its theory.
