HistoryeditThe Center Counter Defense is one of the oldest recorded openings, first recorded as being played between Francesc de Castellv and Narcs Vinyoles in Valencia in 1. Lucena in 1. 49. 7. Analysis by Scandinavian masters in the late 1. Black Ludvig Collijn played the opening with success. Although the Center Counter Defense has never enjoyed widespread popularity among top flight players, Joseph Henry Blackburne and Jacques Mieses often played it, and greatly developed its theory in the late 1. Batman Begins 720P Castellano'>Batman Begins 720P Castellano. It was an occasional choice in this era for top players such as Dr. Siegbert Tarrasch, Rudolph Spielmann, and Dr. Savielly Tartakower. Alexander Alekhine used it to draw against World Champion. Emanuel Lasker at St. Petersburg 1. 91. World Champion Jos Ral Capablanca won twice with it at New York 1. Modern eraeditA regular user from the 1. Yugoslav IM Nikola Karaklajic, but a lengthy period of non support by top players ended by the 1. David Bronstein and womens world champion Nona Gaprindashvili played it occasionally. Danish Grandmaster Bent Larsen, a four time world championship candidate, played it occasionally from the 1. World Champion Anatoly Karpov with it at Montreal 1. The popular name also began to switch from Center Counter Defense to Scandinavian Defense around this time. Danish Grandmaster Curt Hansen is also considered an expert in the opening. Australian Grandmaster Ian Rogers has adopted it frequently starting in the 1. In 1. 99. 5, the Scandinavian Defense made its first appearance in a world chess championship match, in the 1. PCA final at New York City. Viswanathan Anand as Black obtained an excellent position using the opening against Garry Kasparov, although Kasparov won the game. During the sixth round of the 2. Chess Olympiad at Tromso, Magnus Carlsen chose the Scandinavian against Fabiano Caruana, and won Carlsen used the opening again to draw with Caruana at the 2. Chess Olympiad at Baku. The opening is classified under code B0. Encyclopaedia of Chess Openings ECO. Main line 2. exd. White normally continues 2. Black has two major continuations 2. Qxd. 5 and 2. Nf. Marshall Gambit. The rare move 2. Joseph Blackburne on at least one occasion, but is thought to be unsound after 3. Qxd. 5editAfter 2. Qxd. 5, the most commonly played move is 3. Nc. 3 because it attacks the queen with gain of tempo. Against 3. Nc. 3, Black has a few choices. It must be mentioned that although Black does lose a tempo with 2. Qxd. 5, White is going to have to lose a tempo as well to gain an attack. White will have to move the knight on c. Black will have pawns on c. So, the infamous wasted tempo by Black gets returned later in the opening. Qa. 5editThis is considered the classical line, and is currently the most popular option. White can choose from multiple setups. A common line is 4. Nf. 3 Nf. 6 6. Bc. Bf. 5 6. Bg. 4 is a different option. Even though Black has shown that. Bf. 5 can be an excellent move, trading the bishop for the knight after 6. Bg. 4 7. h. 3 Bxf. Bd. 2 e. 6. White has a few options, such as the aggressive 8. Qe. 2, or the quiet 8. Blacks pawn structure pawns on e. CaroKann Defence structure, therefore many CaroKann players wishing to expand their repertoire have adopted this form of the Scandinavian. Its actually an improved CaroKann position because the light squared bishop gets developed outside of the pawn structure. Another setup after 3. Qa. 5 is to target the b. Nf. 6 5. Bg. 2 c. Nf. 3 followed by 0 0, Rb. The line with 4. g. Anand,8Baadur Jobava,9Gyula Sax,1. Francisco Vallejo Pons1. A more speculative approach against 3. Qa. 5 is 4. b. 4, described by Nigel Davies as an ancient gambit line. Grandmasters who have ventured this line as White include Lasker,1. Capablanca,1. 5 and Paul Keres. If Black plays correctly, White should not have sufficient compensation for the sacrificed pawn, but it can be difficult to prove this over the board. Davies suggests delaying the gambit with 4. Nf. 3 Nf. 6 5. b. Qxb. 4 6. a. 4, with the idea of Bc. Qd. 8editThe retreat with 3. Qd. 8 was depicted in CastellviVinyoles, and may be the oldest of all Scandinavian lines. Prior to the 2. 0th century, it was often considered the main line, and was characterized as best by Howard Staunton in his Chess Players Handbook,1. Qa. 5. In the 1. 96. Qd. 8 experienced something of a revival after the move was played in a game by Bronstein against GM Andrija Fuderer in 1. Bronstein ultimately lost the game. Bronsteins game featured the older line 4. Nf. 6, while other grandmasters, including Karl Robatsch, explored fianchetto systems with 4. Ng. 8h. 6. The lines reputation suffered after a string of defeats, however, including two well known miniatures won by Bobby Fischer against Robatsch in the 1. Chess Olympiad later published in My 6. Memorable Games and William Addison in 1. The variation with 4. Fischers crushing win,2. Qd. 8 variation as a whole remains playable, although it is now considered somewhat passive. It is played particularly by International Masters John Bartholomew and Daniel Lowinger, and by the Grandmasters David Garcia and Nikola Djukic. Qd. 6editThe move 3. Qd. 6 offers another way to play against 3. Nc. 3, and it has been growing in popularity in recent years. At first sight the move may look dubious, exposing the queen to a later Nb. Bf. 4, and for many years it was poorly regarded for this reason. Numerous grandmaster games have since shown 3. Qd. 6 to be quite playable, however, and it has been played many times in high level chess since the mid 1. White players against this line have found an effective setup with d. Nf. 3, g. 3, Bg. 2, 0 0, and a future Ne. The variation was covered thoroughly in a 2. Michael Melts. Other 3rd moves for Blackedit3. Qe. 5 the Patzer Variation is regarded as bad for Black for example after 4. Be. 2 c. 6 5. Nf. Qc. 7 6. d. 4 White has a handy lead in development. Likewise the rare 3. Qe. 6 is regarded as inferior. One idea is that after the natural interposition 4. Be. 2, Black plays 4. Qg. 6 attacking the g. However, White will usually sacrifice this pawn by 5. Nf. 3 Qxg. 2 6. Rg. Qh. 3 7. d. 4 with a massive lead in development. David Letterman played this line as Black in a televised game against Garry Kasparov,2. Alternatives to 3. Nc. 3 include 3. d. Nimzowitsch Defense after 3. Nc. 6 1. e. 4 Nc. Python 2.7.5 Source. Qxd. 5, or Black can play 3. After 3. Nc. 6 4. Nf. 3 Bg. 4 5. Be. Black has better development to compensate for Whites center after a future c. Black may also respond to 3. After the usual 4. Black most often plays the pawn sacrifice 4. Qxd. 1 5. Kxd. 1 Nc. After White defends the pawn, Black follows up with. Bg. 4 and. 0 0 0, e. Bb. 5 Bg. 4 7. f. Black has enough compensation for the pawn, because he is better developed and Whites king is stuck in the center. Less popular is 4. Qxe. 5, since the queen has moved twice in the opening and is in the center of the board, where White can attack it with gain of time Nf. However, grandmasters such as Tiviakov have shown that it is not so easy to exploit the centralized queen. Another common response after 2. Qxd. 5 is the noncommittal 3. Nf. 3. After 3. Bg. Be. 2 Nc. 6, White can transpose to main lines with 5. Nf. 6editThe other main branch of the Scandinavian Defense is 2.
