The Keres Defence (also known as the Kangaroo Defence ) is a chess opening characterised by the moves:
3-450: 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. 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
6-492: 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!, 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
9-486: 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) 5.Bxb4 (5.e5 Timman–Spraggett, Montpellier 1985) Qxb4+ 6.Qd2! Qxd2+ (if 6...Nc6 then 7.Nc3!) 7.Nxd2 with slight advantage for White. Bibliography Paul Keres Too Many Requests If you report this error to
