13. Nh2 O-O 14. f3 Kh7 15. Rad1 b6 {With the idea of having the queen defended
if white tries to use Nd5 ideas...but this also closes the diagonal for the
queen to run back to d8 or c7. This move turns out to be quite bad
positionally.} 16. Ng4 Bxg4 17. hxg4 Qa5 {She returns.} 18. Qe2 Nb8 $6 {
White needs to defend against Nd5 threat because it involves Nd5 then Nxf6
then Rd5or simply Nd5 followed by Bd2 depending on how it goes.} (18... Nd7 19.

But this is very complicated. Seems like an easier position for white to play.}

slow down the kingside attack.} (19... Ng8 $142) 20. Rh1 Kg8 21. Nd5 Nxd5 22.
