Trieste, Nato champ and more

Dutch GM Sergei Tiviakov beat Italian prodigy Fabiano Caruana, 15 years old, for the second time in a row. It happened yesterday in Trieste, where the 9th edition of the Chess Festival is under way. Caruana had Black pieces and chose the French defence after Tiviakov’s 1.e4: he reached a lost endgame and couldn’t do anything but resign. The duel was not as thrilling as the one in Vlissingen, where Fabiano lost (resigning a drawn position in deep time trouble), but eventually won the tourney. After round 6 Tiviakov is in sole lead with 5.5 points, while Caruana share the second place on 4.5 (best Italian player by now). The tourney will end on Saturday.

The 18th Nato championship takes place in the Gendarmerie Schools Command in Beytepe, Ankara (Turkey), until Saturday. The tournament follows the structure laid down by the Regulations of the International Military Chess Committee (IMCC) and is a seven-round individual Swiss tournament, with the four highest-scoring players from each country counting towards the team score. Italy doesn’t take part in the competition this year, but many Italian players know at least one participant: German IM Lorenz Drabke (photo), who played in Castione a few days ago, has been living in Northern Italy for many years. He is the second highest rated player of the competition, while his team mate wGM Elizabeth Paehtz is the Elo-favorite. Vytautas Vaznonis from Lithuania is the sole leader with 4.5 points after 5 rounds; Mark Helbig (GER), Drabke, Abel Carrascoso (ESP) and Guido Schott (GER) follow on 4.

Tom Panelas from Chicago wrote a new post about Italian prodigy Marco Codenotti a few days ago: Marco took part in the Knights Quest tourney, finishing second in his division. Full story: http://raychess.blogspot.com/2007/08/reunited.html.
And now here is a brilliant win by Tiviakov in Trieste...

Tiviakov,S. (2648) - Borisek,J. (2506) [C77], Trieste 2.9.2007
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.Qe2
Tiviakov chooses a secondary line he has already played several times. This was an usual continuation in the 18th century.
5...b5 6.Bb3 Be7
The main line, but 6...Bc5 is popular as well.
7.a4
Tiviakov is fond of this variation. 7.0–0 and 7.c3 are more common.
7...Bb7
7...Rb8 and 7...b4 has also been played.
8.c3 0–0 9.0–0 d5 10.d4
10.d3 is less risky; Tiviakov had already played the text move against Bareev in Madrid 13 years ago.
10...Nxe4
This looks to be a new move, The above mentioned game continued 10...dxe4 11.Nxe5 Bd6 12.Bf4 Qe8 13.axb5 axb5 14.Rxa8 Bxa8 and a draw was agreed.
11.dxe5 Nc5 12.Bc2 b4!? 13.Rd1 Ne6
13...f6 was an interesting alternative.
14.a5 bxc3 15.bxc3 Na7?!
Too slow. After 15...Rb8 16.Bb3 d4 Black can easily hold on and can fight to get some counterplay.
16.Na3 c5 17.Nc4!? Qc7?
Black had to be consistent and play 17...Nb5 ; after 18.Qd3 g6 19.Nb6 c4 20.Qd2 Rb8 Black has good defensive resources.
18.Nb6 Rad8 19.Nxd5!
A nice blow, although not difficult to be seen.
19...Bxd5 20.Rxd5 Rxd5 21.Qe4 g6 22.Qxd5
Now White is simply a pawn up.
22...Nc6 23.h4 Rd8 24.Qe4 Nxa5
Black takes the pawn back, but it is just an illusion...
25.h5 c4 26.hxg6 hxg6 27.Be3 Nb3?
27...Nc5 28.Qg4 (intending Bxg6) 28...Nd3 29.e6 was much better for White anyway, but the text move loses on the spot.
28.Rxa6! Nbc5?!
28...Qc8 29.Ra7 Nbc5 30.Qxc4 Rd7 was at least more stubborn.
29.Bxc5 Nxc5
There were no better alternatives, e.g.: 29...Qxc5 30.Rxe6 fxe6 31.Qxg6+ Kf8 32.Qh6+ Ke8 33.Ba4+ Kf7 34.Qh5+ Kg8 (34...Kf8 35.Nd4 Qd5 36.Bc6+-) 35.Ng5 Bxg5 36.Qxg5+ Kh7 37.Qxd8+-
30.Rxg6+!
The decisive blow. Black has no defence.
30...fxg6 31.Qxg6+ Kf8
31...Kh8 32.Qh7#
32.Qh6+ Ke8 33.Bg6+ Kd7 34.Bf5+ Ke8 35.Qh5+ Kf8 36.Qh8+ 1–0
And Black resigned in view of 36...Kf7 37.Ng5+ Bxg5 38.Qh7+ Kf8 39.Qxc7 etc.
