Position after 21.Ne2g3

21...f6

• Stronger is 21...Rc8! 22.Nh5 Ba4 23.Rdd3 Bxb3 24.Rxb3 Qa1+ giving White a won position.

Position after 25.Nh5g7:p

25...e4!

• Black by now is clearly winning.
• If 25...Rxg7? throws away the win to 26.Qxh6 when:
• 26...e4 27.Qh8+ Kf7 28.Rdg3 Rxc2+ 29.Kxc2 is equal.
• 26...Rc4? 27.Rdg3! Kf7 28.Rxg7+ Nxg7 29.Rg3 wins two pieces for White.

26.Rdf3 exf3 27.Nxe8 Bxe8

• Black is up by better than a Rook.

28.Qg4+ Kf8 29.Qxe6

• 29.Qxb4 Rc6 30.gxf3 Rfc7 31.Nd4 a5 32.Qa3 Qc4 wins for White.

29...fxg2!

• Black creates an obvious threat.

30.Qxd6+ Kg8 31.Rg3+

• 31.Qg6+ Rg7 32.Qe6+ Bf7 33.Qxc8+ Kh7 34.Qf5+ Bg6 leaves Black with a won position; White cannot put up too much more resistance.

31...Rg7 32.Qd5+ Kh7 33.Qf5+ Bg6!?

• While this looks best, it's far from it.
• If 33...Rg6! 34.Rxg6 Rxc2+!! 35.Qxc2 Qb1+ then:
• If 36.Kxb1 then after 36...Bxg6 the g-pawn queens.
• If 36.Qxb1 then after 36...Bxg6 37.Qxg6+ Kxg6 the g-pawn queens.

38.Qg3 Qe4 39.Qd3 Qe5 40.Qe3 Qxh2 41.Rg5?

• White seeks to activate her Rook, thinking a pawn sacrifice is a reasonable price.
• 41.Qg3 Qxg3 42.fxg3 Rf7 43.Nd4 Rf2 44.g4 Kh6 remains equal.

• D-na Paulet resigns.
