Lecture by UMBC Chess Coach Igor Epshteyn
This lecture also is about Karlsbad pawn structure in center (White pawns: d4, e3, f2; Black pawns b7, c6, d5 ), but new approach in strategical planning is represented. If previous lecture Karlsbad I described 2 main plans for White - pawn minority attack and central breakthrough e3-e4, here we consider application of famous strategical Principle of 2 Weaknesses to middlegame strategy. It is about most complex and effective type of strategy : combining the upper mentioned plans , creating opportunity for both of them, and 2 weaknesses here are 2 defending spots - Queenside and Center. At the same time should be outlined that complexity and precision of moves order suppose additional chances for both sides.
Realization of any part of plan (march of 'b' pawn or breakthrough e3-e4) leads to enhancing of positional edge for White such as: space gaining, creating week 'd' and/or 'a', 'c' pawns, open lines for rooks, mobile pawn center, etc. Black plans for counter play include simplification of position forcing better endgame, preventing from or reducing weaknesses (for instance, move a7-a6), preparing of c6-c5 with favorable edition of move order. In general, Black plans are more passive but strategically sophisticated.
In 2 represented games one can find different decoration. In 'early bird' of 1977 Candidate match Portish-Larsen bias was made on realization of minority attack, but White provoked premature unfavorable displacement of Black pieces vividly preparing for breakthrough e3-e4. Black failed to solve tactical problems but set stubborn resistance afterwards.
Second game Kramnik-Timman is real masterpiece of strategy created by young chess genius against authority #1(according to games played and score) in this variant. Following this game one can apply the knowledge received in the lectures to the real world of Karlsbad structure and step by step evaluate the finest strategy exposed by the winner.
