Chess: Sicilian Defense[B20]

This tutorial is same to Sicilian Defense of Chess in Spanish

 

Sicilian Defense chess Chess: The Sicilian Defense is the most popular and best-scoring response at chess master level to 1.e4. Black immediately fights for the centre, but by attacking from the c-file (instead of mirroring White's move) he creates an asymmetrical position that leads to complicated situations. Typically, White has the initiative on the kingside while Black obtains counterplay on the queenside, particularly on the c-file after the exchange of Black's c-pawn for White's d-pawn.

Sicilian Defense : How play?

La idea principal de la Defensa Siciliana es, por parte de las negras, contratacar el centro del tablero con un peón lateral desde la primera jugada. De esta manera, si las blancas quieren recuperar la dominación de la casilla d4, deberán realizar el cambio con el peón central de dama, cosa que suele ocurrir en muchísimas de las variantes abiertas de esta defensa.

The Sicilian Defense has much variants

* The B20 series (B20-B29) covers the sidelines where White does not play 2.Nf3. The codes B27 to B29 however cover 2.Nf3 variations, B27 has rare second move responses from Black, B28 covers the O'Kelly Variation (2...a6) while B29 covers the Nimzovitsch Variation (2...Nf6).
* The B30 series covers the lines beginning 1.e4 c5 2.Nf3 Nc6 and which do not have an early ...d6 (which would usually put the opening into the B60 series). The most important variations here are the Rossolimo, Kalashnikov, Sveshnikov and Accelerated Dragon.
* The B40 series covers the lines beginning 1.e4 c5 2.Nf3 e6, most importantly the Taimanov and Kan variations.
