• If 8.d5 Na5 9.Nd2 c5 10.Qc2 Rb8 11.b3 b5 12.Bb2 then:
• 12...e5 13.Rae1 Nh5 14.e4 Bh6 15.Nd1 f5 16.exf5 Bxf5 17.Ne4 bxc4 18.bxc4 Rf7 gives Black the edge in space (Browne-Gunawan, IT, Denpasar, 1982).

• 14.f4 e5 15.dxe6 Bxe6 16.Nd5 Rxb2 17.Qxb2 Bg7 18.Qc1 Black's slight edge in space does not compensate for the exchange.

WHITE: Viktorija Cmilyte
Position after 19...cb5:p

20.Nd5!!

• See the previous note. The Knight radiates power from d5, threatening a fork at either b6 or e7.

20.Nd5 ]
20...Qd8

• This is the only move that satisfies both forking threats, but there's more to come.

21.Bg5!

• White puts more pressure on e7 and at the same time pins the pawn to the Queen.

21...Nf6 22.Nxf6+ exf6

• 22...Bxf6 23.Bxf6 Rxf6 24.Bxb7 Rb8 25.Nc6 Bxc6 26.Bxc6 yields an extra Bishop for White.

23.Bf4!

• Once more, White presents a threat with which Black must deal.

23...Ra7

• A more stubborn defense is 24.Rb1 Kh8 25.Qd2 Ra6 26.Nxb5 Bxb5 27.Rxb5, but Black's pawns would be hopelessly weak.

24...Bxb5 25.Qd5+ Kh8 26.Qxb5 Nc5

• 26...Rf7 27.Rfe1 Rd7 28.Qxf5 Ra5 29.Bd5 Nc5 30.Bc6! wins the exchange at d7, for 30...Rda7 31.Re8+ wins the Queen.

27.Rfd1 Ra6 28.a4 Qc7 29.Rd5 Ra5 30.Bxd6! 1-0


• After 30...Rxb5 the best for which Black can hope is 31.Bxc7 Ne6 32.axb5 Nxc7 33.Rxf5 Rb8 34.Rb1.
• Mr. Akobian resigns.
• This is a fine tactical game by Ms. Cmilyte.
