Position after 10 Rab1?
10.Rab1(loses piece - had to try Nc3-b5) Bxd4
11.Bxd4 Nxd4 12.Na4 Qa5+ 13.c3 Nc6 14.b4 Qe5 15.f3 Qg5 16.Qd2 Qxd2+ (avoid complications and go to end game)
17.Kxd2 d5 18.exd5 Nxd5 19.Bb5 Bd7 20.Nc5 O-O-O 21.Rhe1 Nb8 22.Bxd7+ Nxd7 23.Ne4 N7b6 24.g3 Nxb4+ 25.Ke2 Nc6 !
after cashing in the discovered check to cripple the pawns on the white left - prudence is the better master,
and returning to c6 for the Knight allows defense of the open file and the black left pawns.
26.Ke3? (better seems Ng5 or Rb5) Rd5 27.h4 R8d8 28.Nf2 Rf5 29.f4 Nc4+ 30.Ke2 Rd2+ 31.Kf3 N6e5+ 32.Kg2 Ng4 33.Kh3??
(terrible blunder - should have tried Kf3 NxN, 34. Rf1 with some interesting play left)
Nxf2+ 34.Kg2 Nd3+ 35.Kf1 Nxe1 36.Rxe1 Rb5 37.Re2 Rbb2 38.Rxd2 Rxd2 39.a4 f6 40.g4 h6 [0-1]
Position after 15 ... Qg5 - forcing move against an opponent who wants to play for complications instead
Position after 25 ... Nc6!
Position after 33 Kh3??
Nxf2+ 34.Kg2 Nd3+ 35.Kf1 Nxe1 36.Rxe1 Rb5 37.Re2 Rbb2 38.Rxd2 Rxd2 39.a4 f6 40.g4 h6 [0-1]
