MCC Openings Group

The Melbourne Chess Club hosts an openings study group every second Wednesday. The last time we met we looked at a copy of the openings report from the ChessVibes website. That report is written weekly by 2 Dutch IM's and though interesting, tended to go a bit over our heads. The general opinion of our group was that the publication aimed at players much higher than your average Aussie club player assuming a great deal of prior opening expertise. Of course, this can be labelled at loads of openings works (such as New in Chess Yearbooks) and that players should just start to get down to some work and catch up with the rest of the World.

Whether an article is too high brow, or the readers too lowly in expertise is an interesting philosophical issue, but not one we dwelt on. Instead it was decided that rather than buying openings works, it might be more interesting and useful to try to create one ourselves using the games played at the MCC. So that is what I did, and here it is: (feedback about what you'd lie to see in future copies would be appreciated - Thai Ly already suggested repertoire profiles for prominent players!)

MCC Openings Bulletin

  1. Retain the tension?

Young International Master James Morris decided against the more traditional clearing of the central tension against Jim Papadinis’s Colle set up.

The most popular move here is 7..cxd4. White scores a miserable 37% against this in big database 2010. The most popular reply is 8.cxd4 which seems natural but after 8..d5 9.e5 Ne4, black does not appear worse. So perhaps white could try 8.Nxd4, but after 8..Nc6 black again has nothing to worry about.

Taking that into account, why would an IM play 7..Bg4 in the above position? It has been played rarely and impresses the analysis engines less than 7..cxd4. But can a simple developing move really be that bad? Papdinis replied with the natural 8.0-0 and Morris dramatically changed the position by voluntarily exchanging his bishop, 8..Bxf3. This move is a novelty in the position though the other 3 games in Opening Encyclopedia 2011 all end up in white wins. (8..Nbd7 and 8..cxd4 have been played before) After 9.Bxf3 Nc6 10.d5 [10.dxc5 dxc5 11.Nc4 Qc7 12.Qe2 also has its points, opening the position for the 2 bishops] 10..Ne5 11.Be2 h6 12.Be3 and white enjoys a decent edge. Black’s knights are not secure in the middle of the board, and white can advance on the king side and in the centre quickly.

2. Another g4 attack

20 years ago there was the “risky” Keres Attack and that was about it for g4 attacks. Now, the move g4 gets thrown in all over the place, but especially in the Sicilian. Anthony Hain used g4 in an unusual position against Malcolm Pyke.

1.e4 c5 2.Nf3 Nc6 3.Nc3 d6 4.d4 cxd4 5.Nxd4 Nf6 6.Bc4 e6 7.Bb3 Be7 8.Be3 0–0

In this position, the move 9.g4 is a risk as black can win a pawn by force with the sequence 9..Nxd4 10.Bxd4 e5 when white’s g-pawn is doomed. I suppose the question is whether white is really bothered about losing his g-pawn in this position? It will open the g-file for attack. However, this still seems like a premature flank attack and white’s central king will need to get out of the way or it will become a target.
So should black accept the pawn?
A) 9..Nxd4 10.Bxd4 e5 11.Be3 [11.g5 Ng4 12.Be3 doesn’t look too appealing. Black can choose between 12.Nxe3 or 12.Bxg5] 11..Nxg4 [11..Bxg4 12.f3 Be6 might also be good for black. White will probably castle long and mass his forces on the king side for an all or nothing attack.] 12.Qf3 Nxe3 13.Qxe3 [13.fxe3 Bh4+ will keep white’s king uncomfortable for a while] 13..Bg5 14.Qg3 Bf4 15.Qg2 Be6 seems to leave black a solid pawn to the good, and with the safer king.

B) Malcolm Pyke decided on a safer method (and I must admit that without knowing this line, it would be a huge risk to open the g-file for white’s benefit) eliminating white’s light squared bishop and then meeting the premature flank attack with the classical response, a central reaction.
9..Na5 10.Rg1 [10.g5 seems more in spirit 10..Ne8 (10..Nd7? 11.Bxe6 fxe6 12.Nxe6 Qe8 13.Nc7 with an advantage to white; 10..Nxb3 11.gxf6 Nxa1 12.fxe7 Qxe7 13.Qxa1 again white looks good here) 11.Qd2 Nxb3 12.axb3 with a bit of a mess on the board. Black has some untangling to do but is solid, while white has weaknesses, but a lot of potential especially to mass a king side attack with the simple advance of the h-pawn. I’m not sure who I’d rather be here. 

Back to the game: 10..Nxb3 11.axb3 d5. This is a critical position.

Anthony’s 12.g5 seems misplaced here as it seems more important to deal with the central tension. 2 moves come to mind:

B1) 12.exd5 I’m not sure that I’d be tempted to exchange in the centre with my opponent having 2 bishops and my king in the middle. However, after the exchanging sequence 12..Nxd5 13.Nxd5 Qxd5 and now 14.Qf3 white will be able to castle and his pieces will become quite active in the near future. Black is less developed and will have to defend for some time before his permanent advantages can be brought to the table.

B2) 12.e5 Nd7 13.f4

I am sure Malcolm would have accepted this sort of position as black having great experience with the French Defence. But perhaps this was Anthony’s best chance of a reasonable attacking game without the unnecessary risks he took during the game.

  1. Assess the Novelty

In this position in the game Rujevic-Loh, black played the novelty 9..h6

The position had occurred in a famous game, Fischer-Petrosian Herceg Novi Blitz 1970. In that game, the ex World Champion chose to play 9..Bc6 and didn’t castle king side at all:

Fischer,Robert James - Petrosian,Tigran V [C19]
Herceg Novi blitz Herceg Novi, 1970
 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Qc7 7.Nf3 Ne7 8.a4 Bd7 9.Bd3 Bc6 10.0–0 Nd7 11.Ba3 h6 12.Re1 b6 13.Nd2 Bxa4 14.dxc5 bxc5 15.Qg4 Bc6 16.Qxg7 Rg8 17.Qxh6 Nxe5 18.Bxc5 d4 19.Be4 dxc3 20.Bxc6+ N7xc6 21.Ne4 0–0–0 22.Red1 Ng4 23.Qh4 Rxd1+ 24.Rxd1 f5 25.Nd6+ Kb8 26.Nb5 Qg7 27.Bd6+ Kb7 28.Rb1 Kc8 29.Qg3 Qb7 30.Nxc3 Qa6 31.h3 Nf6 32.Qh4 Nd7 33.Qh7 Rd8 34.Qf7 Qc4 35.Rb3 Qd4 36.Qxe6 Qf6 37.Qd5 Nde5 38.Nb5 Qf7 39.Qc5 Nf3+ 40.Rxf3 Kd7 41.Rd3 1–0

There have been a number of moves tried in the position:

9..Nbc6 (transposing to the main lines of this opening)

Of these moves, 9..Bc6 has been played the most often (not counting the transpositional 9..Nbc6) though Stockfish regards it as a bit dubious after 10.Ng5 h6 11.Qh5.
The powerful engine prefers a move which will not please French players, 9..c4. Closing the centre is not natural to French players and the bishop on d7 looks very sad. But after 10.Be2 Qa5 it looks as if black is winning a pawn either on c3 or a4

Of course, black has used up a lot of time to get this pawn, and white will be able to launch some king side activity, but black has a concrete plan of action, and a winning plan! Exchange, nullify any king side attacking threats, and push the passed a-pawn!

So what about young Zachary Loh’s novelty 9..h6? Well on first glance, it seems to be a waste of time. However, time is not the biggest issue in openings with a closed centre. Zachary obviously wanted to stop Ng5 and so his move is playable. The fact that a master could prove no advantage against it over the board shows it is definitely ok. Although Zac lost the game it wasn’t due to his new move.

  1. Odds and ends

Why is transposing to the Philidor better than playing the Philidor straight off?

Systemic chess…cop out or challenge? 2 games saw white choose a system. In the first the system was used aggressively, while in the second white took a more passive approach.

  1. What's with the wierd notation Carl? Some sort of html chess database program data?

  2. Yes, it was terrible. I have changed the diagrams to chessbase which should make it look better. I had created a doc file and copy and pasted from it. It looked fine in the draft, but I didn't check to see what it looked like on the blog...lesson learnt and I won't be making the same mistake again :)

  3. It's notable that with 1.d4 and 2.c4, that 3.Nf3 seems to be the go these days to Indian set-ups. Why don't they play 3.Nc3 any more?
