As I mentioned last time, I have not gotten a chance to play the Bryntse Gambit <em>in a tournament<\/em> since my game with IM David Pruess. However, I <em>did<\/em> get a chance to play it online, and the result was a fantastic game that may well be the most complex chess game I&#8217;ve ever played.<\/p>\n<p>I didn&#8217;t post the game in my blog at the time, because I wanted to record a ChessLecture about it. However, it has now been 2\u00c2\u00bd years since then, and I think the period of ChessLecture exclusivity has long since expired. Meanwhile, the game (which might be important for the theory of the Bryntse Gambit if there were any theory) has been unavailable to anyone except subscribers of ChessLecture or GameKnot.<\/p>\n<p>So here it is. My opponent was Freddy van der Meij of the Netherlands, known as &#8220;easy19&#8221; on GameKnot. He was fascinated by the Bryntse Gambit, said that he listened to my ChessLecture about it dozens of times (well, maybe this is an exaggeration), and then organized a Bryntse theme tournament on GameKnot, which he won with an undefeated and untied score. Not satisfied yet, he decided to challenge me to a game, which took place in August 2009.<\/p>\n<p>We played at a time control of 3 days per move, although neither of us ever took close to that long (most of our moves were made in less than 1 day). In general, I would say that my inexperience with correspondence chess hurt me a bit. I was not prepared for the stubbornness of his defense, and eventually I allowed a draw in an endgame that should have been won.<\/p>\n<p>Even though the game was a draw, there were three winners. First, the Bryntse Gambit queen sacrifice came out smelling like a rose. Before the game Freddy still said he didn&#8217;t quite believe it was sound (perhaps because he had a prepared variation). After the game, he said he now believed it. Second, Freddy was a winner because he saved a draw after hanging on the precipice of defeat for practically forever. His king escaped no less than thirteen different mate threats! I don&#8217;t know if I have ever seen a monarch survive so many assassination attempts and live to tell about it.<\/p>\n<p>And even I was a winner, because in the early part of the game I got to play an orgy of beautiful sacrifices, all sound: in order, a queen sacrifice, two pawn sacrifices, a knight sacrifice, and an exchange sacrifice. I doubt that I would have found or had the courage to play all of these beautiful moves in an over-the-board game.<\/p>\n<p>Because the game and the comments are so lengthy, I&#8217;m going to do this a little bit differently. In this entry I will post the PGN file so that you can play it through. In my next entry I will post some of the interesting positions from the game in puzzle format. So if you just want to see the game, you can play it through now. If you want to try to solve the puzzles, you should skip reading the rest of this post and read my next post (probably a couple days from now) instead.<\/p>\n<p>Enjoy!<\/p>\n<div><object type=\"application\/x-shockwave-flash\" data=\"http:\/\/chessflash.com\/releases\/latest\/ChessFlash.swf\" width=\"100%\" height=\"550\"><param name=\"movie\" value=\"http:\/\/chessflash.com\/releases\/latest\/ChessFlash.swf\" \/><param name=\"flashvars\" value='orientation=V&#038;tabmode=true&#038;light=eeeeee&#038;dark=BF5C00&#038;border=F5E39E&#038;bordertext=0&#038;headerbackground=E89E47&#038;mtbackground=eeeeee&#038;pgndata=[[Event \"GameKnot\"] [Site \"?\"] [Date \"2009.08.??\"] [Round \"?\"] [White \"Mackenzie, Dana\"] [Black \"van der Meij, Freddy\"] [Result \"1\/2-1\/2\"] [ECO \"B21\"] [Annotator \"Mackenzie,Dana\"] [PlyCount \"89\"] [EventDate \"2012.03.29\"] [SourceDate \"2012.03.29\"]  1. e4 c5 2. f4 d5 3.

Kf5 {Freddy pointed out that I violated my own rule in the Bryntse Gambit: \"Don\u00e2\u20ac\u2122t cash in too soon.\" In my defense, there were two reasons I played the text. First, I thought that I had worked out the tactics to a won endgame for White. (I was right, but it wasn\u00e2\u20ac\u2122t as easy a win as I thought.) Second, I missed the following line:} Be3 (29... Bd2 30. Bxd4 cxd4 31. Bd5%2B Kc2 32. Bf7 Rc8 33. e6 Rc7 {is still somewhat unclear}) 30. Ra3%2B Kc4 31.

Rc3%2B $1 {I had to see this back at move 29, otherwise 29. Bxd4 would have been a blunder.

Ke3 Nc5 {This was the position I saw at move 29, which I evaluated as winning for White. But it turned out to be harder than I thought.} 37. Rf1 Kc3 $1 {Freddy\u00e2\u20ac\u2122s play in this endgame was awesome.} (37... Nxa4 $2 38. Kd4 {and the advance of the e-pawn is too strong.}) 38. Rf7 Re8 39. Kf4 Kd4 40. Rxg7 h6 $1 {This quiet move really took me by surprise. All of a sudden I started to realize that if my rook leaves the seventh rank, it will be very hard for me to stop Black\u00e2\u20ac\u2122s queenside pawns. Therefore I decided that I have to keep my rook on the seventh and infiltrate with the king instead.} 41. Kf5 { I also looked at 41. Rh7, 41. g4, and 41.

It started to dawn on me that even though White\u00e2\u20ac\u2122s bishop is a great defender in the center and on the kingside, it is completely cut off from defending on the queenside and White has to rely on his rook ... or else on winning the pawn race.}) 41... Rxe5%2B 42. Kg6 h5 43. Bxb7 $2 {This was my third choice and it is a third-rate move. I think that what happened was that I was so exhausted after analyzing 43. Rh7? and 43. h4! that I did not have enough energy to analyze this thoroughly enough. I wrote, \"If Bxb7 is going to be necessary eventually, let\u00e2\u20ac\u2122s just play it now.\" I completely underestimated Black\u00e2\u20ac\u2122s response.} (43. h4 $1 {was my second idea and unquestionably the best winning try. However, I just couldn\u00e2\u20ac\u2122t fathom the complications after} a5 $1 (43... Nxa4 44. Rxb7 a6 45. g4) 44. g4 hxg4 45. h5 Re2 {!} 46. h6 Rh2 47. h7 g3 48. Kf5 Nxa4 49. Rg4%2B Kc5 50.

Kxh7 Kb4 {Rybka says that White is winning here, but it also finds the important improvement 51. Bf7! (which takes ... bc off the table and makes the win much more clear).}) (43. Rh7 {was my first idea, but} a5 44. Rxh5 Rxh5 45. Kxh5 b5 $3 {saves the day for Black. This variation again shows the utter uselessness of White\u00e2\u20ac\u2122s bishop for stopping Black\u00e2\u20ac\u2122s queenside pawns.}) 43... a5 $1 44. Bd5 {Of course, 44. Bc6? would be met by 44. ... Re6%2B.} Nxa4 $1 {and now the light finally dawned after me that after 45. Ra7 Nb6! 46. Rxa5 Nxc4! I have walked into a pin and I\u00e2\u20ac\u2122m losing material. Nevertheless, it\u00e2\u20ac\u2122s still a draw after 47. Rb5 Nd6 48. Rb4%2B Kxd5 49. Rh4. So I played 45. Ra7 and offered a draw. Freddy accepted because he felt that White still had a slight edge after 45. Ra7 Nb6 46. Bf7, but I felt that after 46. .. . Rc5! White had absolutely no chance of winning.} 45.
