(3) Christiansen,Larry (2622) - Charbonneau,Pascal (2508) [B70]
USCL Boston vs Baltimore (4), 21.09.2005
[Pascal Charbonneau]

This was not a perfect game by any means. But for sure it was exciting, and maybe even worth a couple of lines of explanation. Let me start off by saying that Larry and I have played quite a lot. First we played, many years ago, in these so-called Banter games on the World Chess Network. At the time I was not even an IM, and Larry got the better of it though I won what we could call my 'fair share'. Later on, WCN organized a match between the American and Canadian champion, and I was out of form and lost a lot of games without a fight. We have since played countless blitz games on ICC, and it's a pretty tough match. In any case, I have to say preparing for a game with Larry is the easiest thing I have ever done. I create a tree in chessbase, I see he plays every move imaginable, and I'm done.

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6
This is my big surprise. I have had three games out of 4 with Black so far, and they have all reached this position. Okay, it's still a bit of a surprise because I have played lots of other things too.

6.Be2
Larry avoids the main complications. But that doesn't mean he doesn't want to play it sharp.

6...Bg7 7.0-0 0-0 8.Nb3
I was unfamiliar with this move order, normally White waits until ...Nc6 (putting pressure on d4 or aiming for a trade) before going this way.

8...a6
An interesting move, I was still considering putting my Knight on d7, and the inclusion of a6 a4 can be useful for Black in some lines (for example, the main line with Nc6, Be6, white plays f4 and Be3, and Black plays . ..Na5-c4, well in this line (I hope I'm being clear!!) this favors Black.

9.a4 Nc6
I decided to revert to the normal path.

10.Bg5
Only to be slightly surprised by Larry's choice. Bg5 is a common idea though, White often plays Re1, Bf1, Nd5, and the Bishop puts pressure on f6 and e7.

10...b6
Not the only scheme of development but a logical one.

11.f4
Re1, with Bf1 is also possible, but I believe Black is OK in that type of position. This move is more unusual and aggressive.

11...Bb7 12.Bf3
And here I could not decide whether e4-e5 was really threatened or not and decided that it was not.

12...Rc8 13.Re1
Larry prepares e5 [13.e5 dxe5 14.fxe5 Nd7 15.e6 fxe6 16.Bg4 Rxf1+ 17.Qxf1 Nf8 And I thought Black was doing well here (and I still think so).]

13...b5?
This was based on a miscalculation (and trying to be unnecessarily fancy). [13...Nd7 is the solid move and should be about equal. White has Nd5 but it does not create much of a threat, and Black's position is harmonious enough.]

14.axb5 axb5 15.e5 Qb6+
[15...b4 was my original intention, with the idea: 16.exf6 (16.Na4 However, this move ends my fun: 16...dxe5 17.fxe5 Nd7 18.e6 And I am ready to resign here!) 16...exf6 and Black is OK.]

16.Kh1 dxe5 17.fxe5 Rfd8
I had decided to sacrifice a piece here, because I thought it was my best practical chance.

18.Qe2 Nxe5
I heard that people thought this was a mouseslip...well, I confess that it wasn't!

19.Bxb7 Qxb7
[19...Neg4 20.h3 offers no hope]

20.Qxe5 b4
Of course I think White should be winning here somehow (how bad was b5!), but the problems to solve are still there.

21.Na5
[21.Qb5 was suggested but is it so clear? 21...Qxb5 22.Nxb5 Rxc2 (22...Rd5 23.Na7 Rxc2 24.Rac1 Rxc1 25.Bxc1 ) 23.Rxe7 Rxb2 and Fritz etc. like White a lot, but in practice I think you're a bit afraid Black might give you problems in something like this.]

21...Qa8! 22.Qxe7?
After this move nothing is clear.

22...bxc3 23.Nb7 Re8!
Maybe Larry missed this idea. You always want to find ways to fight in team matches, and so I was happy to have this 'trap' and saw it as a way to thank my teammates for having good positions.

24.Rxa8 Rxa8 25.Qxe8+
[25.Bxf6 Rxe7 26.Bxe7 cxb2 with Ra1 could also be what White missed when assessing Qxe7.]

25...Nxe8
I preferred to keep Rooks as I thought I could give White problems defending their c-pawns with the Rooks on the board. Of course this is a drawn endgame, but Larry felt obliged to try to win as Boston was trailing 2-0.

26.bxc3 Bxc3 27.Rd1 Nc7 28.Nc5 Ne6 29.Nxe6 fxe6 30.g3 Ra5 31.Bh6 Bf6
I love to play this, with dreams of playing g5 and eating the Bishop on h6 for a late game snack.

32.Rd6 Kf7 33.Rc6 g5
White is getting in some trouble here.

34.Kg2 Ra8
I am getting closer to the time of my snack.

35.h4 gxh4 36.g4
[36.gxh4 keeps excellent drawing chances, but Larry still had hopes to win.]

36...Ra4
with the idea 37. g5 Bxg5

37.c4
[37.g5 was still the best chance. I played this part quite carelessly, as I knew my team would win. On the other hand, I would not take a draw here as I had a risk free position, it's just kind of hard to play these well, but we all know tiebreaks might matter later on.]

37...Ra2+ 38.Kf3 h3 39.Rb6 h2 40.Rb1 Bd4
Threatening to play Bg1

41.Rh1 e5 42.Bg5 Ke6 43.Bh4 Bg1
now the Rook is jailed.

44.Bg3 Rc2 45.c5 Kd5 46.g5 e4+ 47.Kf4 e3
this is fine but easier was [47...Bxc5 ]

48.Bxh2 Bxh2+ 49.Kxe3 Kxc5 50.Kd3 Rg2
Now there are technical problems to keep the Pawns on the board, although I have had lots of success winning (and losing) R+B vs R.

51.Ke4 Kd6 52.Kf3 Rb2 53.Kg4 Ke6 54.Kh5 Kf7 55.Rd1 Rb7 56.Kh6 Ke6 57.Rf1 Be5 58.g6 hxg6 59.Kxg6 Rg7+ 60.Kh5 Bf6
I think White can still set up a drawn position here, but it's not the easiest case.

61.Re1+ Kf7 62.Re4?
This allows a pretty finish, because the Rook is badly placed on the fourth.

62...Rg5+ 63.Kh6 Rf5!
And the only way to stop Bg7+ and Rh5 mate is:

64.Rg4 Rf1
When the Rook gets in the way. 0-1
