after only 12 moves. Black's Queen's Indian Defense has morphed into a sort of
Benoni, albeit with an unusually weak d5-pawn.13.b4?!...Playing on the side
where he is less developed and has less space is counterintuitive, but perhaps
White overestimated the threat of ...b5-b4.13.Ng5is a thematic way to
exploit the inclusion of h2-h4 and ...h7-h5. White prepares e2-e4 and can also
consider f2-f3 with g2-g4 ideas to play on the side where he is stronger.b414.axb4cxb415.Nce4!Nxe4(15...Nxd5!?16.Nd6!Qb617.Nc4Qc518.e4⩲is the sort of position that should give White compensation for the pawn
(and thensome) given the powerful knights and open files.)13....cxb414.axb4a5!Black is happy to liquidate the queenside when White is several
tempi away from castling.15.Nxb5axb416.Rxa8Bxa817.Qxb4Qb618.e4Re8The point of Black's decision to capture the b4-pawn rather than the d5-pawn:
provoking e2-e4 plays into Black's development.19.Nd2Bxd520.f3?!...20.Bd3Na621.Qc3Bc622.Nd4Nb4⩱20....Nc621.Qc3...White is behind in
development, presumably won't castle any time soon, and has some problems on
the back rank and queenside. But the threat of g2-g4 against the weak, pinned
f6-knight might make all of those static considerations moot. Black has a
number of defensive moves here, but White also has a few tricks. Black walks
into one:21....Ne5??21...Be6!The obvious move looks to play into White's
attacking plans with22.g4hxg423.h5gxh524.Rxh5when White's
initiative is obviously terrifying, but deeper calculation would reveal that
Black is for choice afterRa8!when there is no time to go after the
knight, as25.Rg5+Kf826.Qxf6Qe3+27.Be2loses, even though the
a1-square is covered, since there is no answer toRa2!when the queen
cannot retreat to c3 as the g5-rook falls.22.Nc7...White wins material.22....Rc822...Re723.Nxd5Nxd524.exd5+−23.Nxd5Qb823...Nxd524.Qxe5+!Black might have relied on assuming Black would play(24.Qxc8?Qe3+25.Kd1Nc3+26.Kc2Nc6!)Nf625.Qa1!+−24.Qd4Nxd525.exd5Rc1+26.Kf2f6There is no more attack, and White is simply up a piece.27.Rg1Qd628.Be2Nc629.Qe3Rxg130.Kxg1Qxd531.Bc41-0 White wins.1-0
