The Keres Defence (also known as the Kangaroo Defence or Franco-Indian Defence) is a chess opening characterised by the moves:
The opening is named after Estonian grandmaster Paul Keres.
This opening was known since the 1840s and was played by Henry Thomas Buckle in his fourth match game with Johann Löwenthal, London 1851. [1] [2] The standard reply today, 3.Bd2, was recommended by Howard Staunton.
White can respond 3.Nc3, 3.Nd2, or 3.Bd2. The game often transposes to a Nimzo-Indian Defence, a Dutch Defence, a Queen's Gambit Declined, an English Defence, or a Bogo-Indian Defence. 3.Nc3 is likely to transpose into one of those openings: 3...Nf6 (Nimzo-Indian), 3...f5 (Dutch; Korn gives 3...Bxc3+ 4.bxc3 f5!, [3] played by Buckle) 3...d5 (an unusual form of QGD), or 3...b6 (English). Black has the same options after 3.Nd2, except that 3...Nf6 4.Nf3 is a Bogo-Indian.
After 3.Bd2, Black can continue with 3...Bxd2+ into a line of the Bogo-Indian, and 3...a5 will also usually transpose to a Bogo-Indian when White plays Nf3. Or Black can allow White to play e4: 3...Qe7 4.e4 d5 (Black obtained a good game in Llanos–Hoffman, San Luis Clarin 1995 with 4...Nf6 5.a3 Bxd2+ 6.Nxd2 d6 7.Bd3 e5 8.d5 0-0) [4] 5.Bxb4 (5.e5 Timman–Spraggett, Montpellier 1985) [5] [6] Qxb4+ 6.Qd2! Qxd2+ (if 6...Nc6 then 7.Nc3!) 7.Nxd2 with slight advantage for White. [7]

The Pirc Defence is a chess opening characterised by the response of Black to 1.e4 with 1...d6 and 2...Nf6, followed by ...g6 and ...Bg7, while allowing White to establish a centre with pawns on d4 and e4. It is named after the Slovenian grandmaster Vasja Pirc.

In chess, a transposition is a sequence of moves that results in a position which may also be reached by another, more common sequence of moves. Transpositions are particularly common in the opening, where a given position may be reached by different sequences of moves. Players sometimes use transpositions deliberately, to avoid variations they dislike, lure opponents into unfamiliar or uncomfortable territory or simply to worry opponents.
In chess, the Maróczy Bind is a term alternately used to refer to an opening or its associated pawn structure, named for the Hungarian grandmaster Géza Maróczy. When the Bind is discussed as an opening, it is defined as 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6 5. c4.
