Subject: test position from GM game 9...Nxb4.

Interesting Game between two 2600 GM's. Mate in 29 moves.


GM Short played   9...Nxb4  starting his attack.
 [D] r1bq1rk1/pp3ppp/2n1pn2/2bp4/1PP2B2/P1N1PN2/5PPP/R2QKB1R b KQ - 4 1


GM Epishin played       12.0-0-0
some programs play    12.Rc1
maybe this was the losing move for white.
 [D] r1bq1rk1/1p3ppp/4pn2/p2p4/1bP2B2/1QN1PN2/5PPP/R3KB1R w KQ - 4 1

several more weak moves by white. after white castles and moves his king
in the middle of the battle, black keeps pressure on white,
white must defend and  never plays the Rook at h1, or gets
any chance to use the Knight at f3.


GM Epishin played 22.Qd2   which is mate in 8. black wins
 [D] 2r3k1/4qp1p/4pp2/1P1p4/p7/b1rRPN2/3QBPPP/1K5R b - - 0 22

First two games below,GM Short playing black is in same 9.b4 position, but GM
Short plays 9...Bd6 and 9...Be7

next three games show that 9...Nxb4  has been played before by black.
I had not seen this move before, but Topalov playing black won with 9...Nxb4
blindfolded!  So it seems this is old move.
Have you seen this move in any program book?
