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. Ng5 { is 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. } 13... b4 14. axb4 cxb4 15. Nce4! Nxe4 (15... Nxd5!? 16. Nd6! Qb6 17.

Nxb5 axb4 16. Rxa8 Bxa8 17. Qxb4 Qb6 18. e4 Re8 { The point of Black's decision to capture the b4-pawn rather than the d5-pawn: provoking e2-e4 plays into Black's development. } 19. Nd2 Bxd5 20. f3?!

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 with } 22. g4 hxg4 23. h5 gxh5 24.
