12,12,42,42,58,37,37,12,54,45,45,33,33,45] Duda surprises Rapport with a
Rapport-style opening treatment and quickly gets a winning position after a
curious opening mistake from the "Hungarian." Lacklustre play at the critical
moment spoils the advantage. Later, a chance to get a winning ending is missed
by Duda, suggesting that he is not quite ready to perform on the very top

overwhelming advantage. It is important to understand that afterO-O12.O-OBxb2?!13.Rb1Bg714.e5Black would be entirely tied up. The extra pawn
counts for naught.10.Bg5Bg711.cxd6Qxd612.O-OBe613.Na3!?...A bit
awkward. 13.Nc3 with the idea Na4-c5 felt more natural. And the computer says
that13.Ba6!Qxd114.Rxd1f615.Be3Kf716.Nd2is completely winning.
The knight is coming to b3 or c4, and from there to a5, c5 or d6.13....Rd814.Be2Qxd115.Rfxd1Rxd1+The first critical moment of the game.16.Bxd1?...A horrible move. White obviously would prefer to play16.Rxd1!, which is only negatable because ofBxa2, when 17.Nc4!? is tempting,
giving White a clear advantage. But even more convincing is17.Nb5!(17.Nc4Bxc418.Bxc4h619.Be3Nc820.Ba6Nb621.Rd6and White is technically

the moment. Over the next ten moves what remains of his advantage slowly

no means obvious. A key point is that afterBd437.g4!White either
creates a massive weakness on h5, or gets a passed h-pawn. A lot of play
remains, but White seems strategically winning.33.Rd3?...33.a4!would be an even better version of the previous variation. White is not
parting with the b-pawn here. The structure favors White and the two bishops
will put pressure on a5, g6 and h5. It is just too many weaknesses to handle.

manner...33....Bd434.Rb3+Kc635.Bxa5Ra836.Rb6+Kd737.Ra6Rxa638.Bxa6Bxb239.a4c440.Bb4h441.Ke2Kc642.Ba5Bc143.Bd8Bg544.Kd1Kd745.Bb6Kc646.a5Bf447.Kc2f548.Kc3fxe449.fxe4Nxe4+50.Kxc4Nd6+51.Kb4Bxh252.Be2e453.Bc5Nf554.Bb5+Kc755.Bb6+Kb756.Bc4Nd657.Be2Kc658.Bc5Nf559.Bb5+Kc760.a6Bd661.a7Bxc5+62.Kxc5Kb763.Bc6+Kxa764.Bxe4Ne365.Kd4Nxg266.Bxg2g567.Bh3g468.Bxg4h369.Bxh31/2-1/2 The game is a draw.1/2-1/2
