The Boleslavsky Variation

We have already discussed the Sicilian Boleslavsky Structure characterized by black pawns on d6 and e5, against a white pawn on e4. Strictly speaking, in modern times the Boleslavsky Variation is said to occur when White plays 6 jte2 after the opening sequence 1 e4 c5 2 < > f3 Zhc6 3 d4 cxd4 4 xd4 > f6 5 ic3 d6 and Black follows with e5. However similar positions and structures can occur from various opening move sequences by either player. Let us look at some typical examples of games...

The c Sicilian Variation in

Which White plays 2 c3, hoping for an early d4 with a big centre and chances of a kingside attack. D. The Kopec System in which White plays 2 > f3 and 3 d3. E. Closed Systems with Ab5, e.g., 1 e4, 2 & f3 and 3 jtb5 against My feeling about all these systems is that they should not create major problems for the Sicilian Defence if Black plays logically. Sure, it helps to know specific variations and have some experience with them, but none of these systems, in themselves, should be so...

The Characteristic Boleslavsky Structure

The Paulsen or Boleslavsky structure arises when Black plays an early e5 or, as mentioned earlier, it can be reached from a Scheveningen or Najdorf when Black plays e5, usually after an earlier e6. The Paulsen structures are distinct from the Najdorf in that in the Paulsen Black's queen's knight is ordinarily developed on c6 while in the Najdorf the queen's knight is developed on d7. White usually follows with f4, establishing a duo. Then Black may capture on f4 with exf4, followed by hz5. The...
