Stooflees had the black pieces against Arasan, and played the Marshall Attack after the book opening. Black went with an unconventional strategy targeting the a2-pawn, which later yielded black a strong outside protected passed pawn on a7. Kingscrusher suggests that this strategy may be a novelty in the Marshall Attack.

End of the opening book.

Black queen has infiltrated white's position and is ready to capture the a2-pawn. 29. c4 is the only move for white here, creating an interesting dynamic: connected passed pawns c4 and d4 for white against outside passed pawn potential for black (pawns on a6 and b4 against pawn on b2).

White cannot realistically prevent black from getting the pawn majority on a and b files. After 29. cxb4 Ba4 white will lose an exchange with little compensation. If white is stubborn, then 30. Rf1 h3 and white's position will soon collapse.

The position is now simplified to a rook and opposite colored bishop ending. Black has now a decisive advantage: The white bishop cannot help in defending against the pawn on a7 from queening, but black's bishop can defend against c and d pawns.
