(1) Lupulescu,Constantin (2599) - Marin,Mihail (2616) [C50]
ROM-chT Eforie Nord, 22.09.2009
[Marin for CBM online]

Over the past few months, I have annotated some games in which I had had the opportunity to use for the purpose of preparation one of my own theoretical articles published in ChessBase Magazine. In my last tournament, a slightly different situation ocurred.

1.e4 e5 2.Nf3 Nc6 3.Bc4
In our previous encounters, Lupulescu had twice deviated from his main weapon, the Ruy Lopez. This time, I thought he would finally go for the main lines, but got another surprise.

3...d6
I had examined this only apparently modest move in an article published in CBM 128; slightly later, I had the occasion to defend Black's point of view against Tiviakov, at Porto Mannu 2009 (see my comments for CBM 131). However, I did not have the time to re-read my article before the present game, since I was more concerned about checking the viability of the main lines of the Ruy Lopez.

4.d4 exd4 5.Nxd4 g6 6.Nc3 Bg7 7.Be3 Nf6 8.Qd2
[This is the most ambitious continuation, preparing to castle long. Tiviakov preferred the more modest 8.Nxc6 bxc6 9.0-0 ]

8...0-0 9.0-0-0 Re8 10.f3 Ne5 11.Be2
[This is a loss of tempo, but the bishop is exposed after 11.Bb3 a6 in view of the threats ...b5 followed by ...c5-c4. Although the position ressembles a bit the Sicilian Dragon, the presence of a black pawn on the c-file makes things a lot different.]

11...a6 12.Nb3
[This was the first new move for me. I vaguely remembered 12.Bg5 b5 13.Nd5 and I was pretty sure that I had reccomended an improvement over a game played by Palkovi (The game is Palkovi,J (2350)-Hammergren,P/Eger 1987/EXT 97/[Mihail Marin] (1-0, 40) and my line went: 13...c5! 14.Nb3 Be6 )]

12...b5
One of Black's main threats is ...Nc4, when White's b3-knight would have to jump around again.

13.Bg5 Be6 14.Nd5
At this moment I had my first really long thought. Comically, I had no idea that...

14...c5!
...basically transposed to my own recomendation! [White gets excellent chances to maintain the domination in the centre after 14...Bxd5 15.exd5 Nc4 16.Bxc4 bxc4 17.Na5 (17.Nd4 allows Black to activate his queen with 17...Qb8 ) 17...Qd7 (After 17...Qb8 18.Nxc4 Black has no compensation.) 18.Nc6! White avoids 18.Nxc4?! Qa4! with counterplay and maintains a stable plus.]

15.Nxf6+
[One of the lines I had analyzed is 15.Nf4 Nxe4! 16.Nxe6 Nxd2 17.Nxd8 Nxb3+ 18.axb3 f6 19.Rxd6 fxg5= ]

15...Bxf6 16.Bxf6
[The interesting thing is that in my original notes I did not consider this exchange seriously and examined the more principled 16.h4 when after 16...Nc4! 17.Bxc4 bxc4 the white knight would have a hard life.]

16...Qxf6
The game prematurely ended in a draw here, just about when the position had become really interesting. [After 16...Qxf6 I intended to meet 17.Qxd6 with 17...c4 , eventually followed by ...Rad8 and ...Qg5+. In some lines Black retrieves the pawn, while in others he just gets excellent compenstaion for it. 18.Nc5 (The apparently solid 18.Nd2 leads to disaster after 18...Red8 19.Qb6 Nd3+! 20.cxd3 cxd3 21.Bf1 Rac8+ 22.Kb1 Bxa2+!-+ ) 18...Rad8 19.Qb6 (19.Qxa6 Ra8 20.Qxb5? Reb8 ) 19...Qg5+ 20.Kb1 Qxg2 (During the post-mortem we analysed 20...Rxd1+ 21.Rxd1 Qxg2 22.Nxe6 Qxe2? concluding that Black is winning, because White's pieces are hanging. Fritz has another opinion: 23.Qd8!!+- Suddenly, the black king is in deadly danger.) 21.Rxd8 Qxh1+ 22.Bd1 Kg7 23.Nxe6+ Rxe6 24.Qf2 b4 [with initiative] This is another of our post-mortem lines, which seems to be correct. White's control over the only open file offers him the hope of keeping Black's overall activity within bearable limits. Although I cannot be satisfied with my fighting spirit (not to mention my poor memory!), I certainly am content that the rare variation based on 3...d6 passed the test of another strong opponent.] 1/2-1/2
