Im Sorry
27...h5 28.Kg2 is also better for black but not completley lost or white.
I thought 28.Kg2 is not possible and forgot about Shredder 7 special code.
He never likes to take a knight on g4 or g5.
[D] 1k4q1/pp1n4/1bp5/4p2p/1P2P1n1/2PP1RPP/P2B4/R2N3K w - h6 0 1
Analysis by Shredder 7.04:
1. -+ (-1.77): 28.Le1 a6 29.c4 Ld4 30.Tb1 De6 31.a4 Se3 32.Txe3 Dxh3+ 33.Kg1
Lxe3+ 34.Sxe3 h4

Kc7
3. -+ (-1.91): 28.Kg2 h4 is complete nonsense of course. Ngf6 or Qh7 is
necessary.
