This seems to be dubious to me, offering the opening of the long diagnol with a Bg7 staring at a Ra1. However, Jacob has been known for getting away with the dubious. 12...b5 [ 12...exf4 seems to me to be a right reaction. 13.gxf4 b6 ( 13...d5 14.cxd5 cxd5 15.exd5 Nc7 16.Bxa7) 14.f5 Nc7 15.Nd4 Bd7 ( 15...c5 16.Nc6) 16.b5 ( 16.Rb1 c5) 16...cxb5 17.cxb5] 13.cxb5 cxb5 14.f5 Now he manages to keep the long diagnol closed. I think this is an achievement for white. 14...Nc7 15.g4 [ 15.Bxa7 Ra8 16.Be3 gxf5 allows black to open the center back up. It could be double edged, as white has a long diagnol of his own for counterplay now. However, the half open a-file looks ripe for black to penetrate, after which he is free to think about playing e5-e4. I perfer white's play in the text. It's the sort of thing I like to go for as well. Instead of going pawn grabbing, white maintains a blocked center and bolsters f5, inviting white to take so he can open the g-file. 17.exf5 Ra3 18.Bc1 Ra6] 15...d5?! not only does this move ignore the long diagnol, practically killing the Bg7, it threatens a fork that practically forces white to take the pawn. The positive side of these developments is that it leads to the interesting material imbalances that result in the game. 16.Bxa7 Bb7!? Diagram The engines don't like this, but I find it interesting. I had Jacob sac TWO exchanges on me and win. Hence, I guess black operates under the theory that do get the advantage he must try something similar.17.Bxb8 [ 17.g5 is an interesting zwishenzug rated approximately equivalent to the text by the engines. 17...Nd7 ( The engines disagree and 17...Ra8 is Fritz's favorite. 18.gxf6 Qxf6 19.Bc5 Diagram 19...d4 interesting preliminary choice by Crafty. ( 19...Rfd8 20.exd5 Nxd5 21.Nxb5 e4 22.dxe4 Nxb4 23.Qb3 Na6 24.Bd4 ( 24.Nc7? Nxc5) 24...Rxd4 Crafty's choice! Things are starting to get rather out of hand here... 25.Nbxd4 Nc5 I know. I am totally off my rocker.) 20.Bxf8 Bxf8 21.fxg6 ( 21.Nxb5 Nxb5 22.fxg6) 21...Qxg6 22.Rf3 Kh8 23.Nd5 Nxd5 24.exd5 Bxd5 ( 24...Bxb4 25.Qb3 Bd2 26.Qxb5) 25.Rg3 Qe6 26.Bxd5 Qxd5 27.a3 when there really shouldn't be enough. Black no longer has the two bishops, the Bf8 is not the superstar that black needs to overcome this immense material deficit.) 18.Bxb8 ( 18.f6 Ra8) 18...Nxb8 19.f6 Bh8 I am starting to think of the "zwischenzug" as superior to the text at this point. Black is going to have to try ..h6, but then white can answer with h4. The Bh8 of course is an absurd piece. Probably black will have to resort to ..Ne8xf6 but then he will be down a whole rook with but a pawn to show for it.] 17...Qxb8 18.d4?? I don't see any point in this. It is black who has the two bishops so wants the open game. True, white has two rooks who also like open positions, but they can do jus as well with files. It also drops about a pawn and a half of material according to the engines. [ 18.a4 bxa4 19.Qxa4 drops a little less material, and gives white a passed b pawn. The rooks have three beautiful queenside pawns to play with. Opening the center only helps the Bg7, and finally white is overlooking the crushing positional advantage he could get with the "zwischenzug," which by the way was still on but is slipping away now.. 19...g5 puts pawns on dark squares but ironically helps the Bg7. The "zwischenzug" is no longer possible.; 18.g5 Qa7+ 19.Kh1 Nd7 Diagram 20.f6 a) I don't know why the engines are showing any inclination to play 20.Nxd5 Nxd5 21.exd5 f6; b) 20.a4 gxf5 21.exf5 Qe3 22.f6 d4 23.Ne4 Bxe4 Diagram (b) 23...Bh8? just asks to play down another piece.) 24.dxe4 (b) 24.Bxe4? has a deficiency 24...Qxh3+ 25.Kg1 Qe3+ 26.Kh2 Qxg5 27.fxg7 Qh6+ 28.Kg1 Qxg7+ 29.Bg2 Nd5 30.Rf2 Ne3 31.Qd2 bxa4 32.Rxa4 Nf6 Diagram 33.Ng3 Black is starting to realize a bit of compensation. The engines are reducing white's advantage. The Ne3 and the f4 square for the other knight are rather pretty. However, the passed b-pawn is a big consideration and in light of what just happened in the other alternative I am going to have to explore this line further.. (b) 33.Nc1 Nfd5 34.Nb3 Qg4 (b) Crafty likes 34...Nf4 but the immediate reaction is 35.Rxf4 exf4 36.Qf2 Kh8 37.Qf3 Rg8 38.Ra2 Qe5 (b) 38...Qg3 39.Qxg3 Rxg3 40.Nxd4) 39.Ra8 this is a real stuggle, but white is getting the upper hand.) 35.Nc5 (b) 35.b5 Rb8) 35...Nf4 36.Ne4 Kh8 37.Nf6 Qg6 38.Ra6 Nxd3 (b) 38...Rg8 39.Nxg8 Qxa6; b) 38...Nh3+ 39.Kh2) 39.Re2 (b) 39.Rf3 Nxg2 40.Qxg2 Qxg2+ 41.Kxg2 Ne1+) 39...Nf4 40.Qa2 (b) 40.Rxe3? dxe3 41.Qb2 e2) 40...Nxe2+ 41.Qxe2 Fascinating.

It would probably be a hard move to make, however, as white's advantage is a bit small, with his deficit in king safety.] 23...Kg7 24.g5?! [ 24.Bxb7 Qxb7 25.Qc2 Nd5 and again we have a beautiful knight outpost on e3. Jacob's choice is leaning away from the dubious into the question mark department. It pops up as Crafty's favorite for a split second, but then steadily slips down the list down the list as the event horizon looms. Fritz considers it the #2 move for an even tinier split second and it then disappears from the top 10 immediately, never to be seen again.] 24...Bxg5 25.Rxf8 Qxf8 26.Rf1 [ Perhaps Jacob had an hallucination that he could at some point play 26.Nxd4? Be3+] 26...Be3+ 27.Kh2 Qd6+ both engines see massive pluses for black. The "material count" is perfectly equal, but nothing else about this position is. 28.Ng3 Bd5 now white has to trade a contender for his best piece. The Rf1 is happy on his file, and he is working well with the Qb3. However, all of black's pieces plus the monsters on c3 and d4 are steadily raining down onto white's position like the World Trade Center on the morning of September 11. The pin that ensues along the a2-g8 diagnol is ever so slightly irritating to black but it is a concern akin to a mosquito attacking a heard of charging rhinos. 29.Bxd5 Nxd5 Diagram 30.Rf3 [ Fritz perfers two moves that to me strike out as the most sensible concept for white's postion..die blockade. However They do have a serious flaw.. 30.Qc2 Nxb4 31.Qe4 c2 32.Qb7+ Kh6 and the black king rests safely on his front lawn.; 30.Qd1 Nxb4 31.Qf3 This has to be a reasonable try, circumventing the black knight's blockade of the a2-g8 diagnol.

[ even if 34...Kf7 35.Qg7+ (the idea behind the knight sacrifice) 35...Ke8 36.Qxh7 Nf4+ 37.Kh2 Ne6 black has ample resources for the defense, but of course the text solves this in a pretty and final way.] 0-1
