Why let White take the bishop on g6 (I think Black is better after that also, though)? 12...Bf5 is clearly better for Black. Maybe 10...Nd5 would be ok as well. Anyway, after 12...Bf5, with ...h6 and ...Nbd7 coming up.  It looks like a traditional Caro-Kann/Scandinavian pawn structure but with an extra pawn for Black. Next up is ...c5 and bringing a rook to the centre. Where is White's compensation?

According to the game score, Go - Donchenko continued 9 Ne2 c5 10 c3 h6 11 Nxe6 fxe6 12 Nf4 Bf7 13 Be6 Be6 14 Ne6 Qb6

In the game Benjamin Go - Alexander Donchenko, Groningen 2013, White could have received a long-lasting initiative after 15 Rxf6! gxf6 16 Qh5+ Kd7 17 Qf7 Be7 18 d5 Nc6 19 dc6 Qc6 20 Bf4 Rag8 21 g3 Re8 22 Nc7 Kc8, etc.

Instead, 15 Qe2?! as played in the game, is evaluated as 0.00 by my chess engine. White went on to lose because he did not attack ferociously enough. This is the whole point of the Ng5 - line!

And yes, I do have a solution. After 9 Ne2 Bd6 10 Bf4! exchanges the Bd6 and uses the Ne2-f4 maneuver to put pressure on the Kingside. I won some games after something like  10...00 11 Bd6 Qd6 12 Nf4 Nbd7 13 Nxg6 hxg6 14 c3  with an upcoming Qe1 - Qh4 maneuver.

Will post some ICC  games once I locate them.

Maybe 9. Ne2 Bd6 10. Nf4 Bxf4 11. Bxf4 (and Black is better after 11...0-0!)?

The other moves have been 9. Bxe6?, 9. Be3 and 9. Re1. White has 2 draws against 10 Black wins in the Chessbase online database (4 correspondence games, the rest long time control). Avrukh's conclusion is that there is nothing for White at all in this very variation. I can't say I disagree, and haven't seen any other analysis that should overturn the verdict.

But of course Gambit has some based on ICC blitz games?

What exactly did White play after 1 e4 c6 2 d4 d5 3 Nc3 dxe4 4 f3 exf3 5 Nxf3 Nf6 6 Bc4 Bf5 7 00 e6 8 Ng5 Bg6 ? I would like to see some of the game scores. Did White play inaccurately somewhere?

When I play these lines in blitz at the Internet Chess Club, I win far more than I lose. Yes, the time control is less, but I also likely play better moves.

In the game Benjamin Go - Alexander Donchenko, Groningen 2013, White could have received a long-lasting initiative after 15 Rxf6! gxf6 16 Qh5+ Kd7 17 Qf7 Be7 18 d5 Nc6 19 dc6 Qc6 20 Bf4 Rag8 21 g3 Re8 22 Nc7 Kc8, etc.

Instead, 15 Qe2?! as played in the game, is evaluated as 0.00 by my chess engine. White went on to lose because he did not attack ferociously enough. This is the whole point of the Ng5 - line!

Edit: just checked the dates. Looks like the Schandorff book on the Caro Kann line against the BDG Gambit came out in 2010. The Scheerer book on the BDG came out in 2011. Looks like the Schandorff book on the Caro Kann line against the BDG may be out of date and needs a refresh to deal with the new line.


I found 5 tournament games since 2012 with 1.e4 c6 2.d4 d5 3.Nc3 dxe 4.f3 exf3 5.Nxf3 Bf5 6.Bc4 e6 7.O-O Nf5 8.Ng5 Bg6.

Black won all of them. Also found 4 correspondence games and black won all of them. Maybe that's why Schandorff did not mention this line?

That is correct. The Rat is the 1970s name for the Modern.

The Rat is the Modern.  As far as I know, the nickname is associated with the creative/eccentric Canadian grandmaster Duncan Suttles.

Wait...you play the Rat in lieu of the possibility to face the BDG in like, what, 1 out of every 20 games as Black?

Shocked

Well, maybe I'm quoting the wrong opening. The Rat is the Pirc, correct? So, no...I don't play the Pirc. I play the Modern Defence. This way I don't have to worry about e5 moves kicking the knight on f6.

As for my opening choice as Black...I'm getting lazy. I'm comfortable with g6 lines against practically anything White throws at me. I mean, if my opponent is booked up on the Four Knights Game...I certainly don't plan on remembering lines to the Rubinstein variation! Or playing the Quaade line in the King's Gambit should White try that if I play 1...e5.

Yeah, the Rat is named that way for a reason. What does the rat do? Hide from the big bad cat! So here you have 1...g6 to avoid all the fun!

And yes, the Scharndorff book is outdated.

I wish I had the BDG in 1/20 games as Black!

Correct me if I'm wrong here but I looked through the Lars Schandorff book on the Caro Kann by Quality Chess and on page 236 he offers a line to deal with the BDG Gambit. But I'm curious to know if his suggestion works because the one he offers is the old Main Line against the Ziegler Defense with 7/8.Ne5. As far as I can tell he doesn't mention the newer line that White has his/her disposal...which is 8.Ng5 which is mentioned in the Scheerer book. Could that be because the Schandorff book on the Caro Kann came out eariler than the Scheerer book on the BDG Gambit? I don't know the publication dates.

Edit: just checked the dates. Looks like the Schandorff book on the Caro Kann line against the BDG Gambit came out in 2010. The Scheerer book on the BDG came out in 2011. Looks like the Schandorff book on the Caro Kann line against the BDG may be out of date and needs a refresh to deal with the new line.

It's for this reason I no longer use the Caro Kann Defense as Black...because I don't want to face the BDG Gambit. I'll stick to the Rat/Modern Defense.

In checking with the computer, I found that Scheerer's analyses of the Kampars Gambit line gives inferior moves for White at critical points. How so? Judge for yourself:

1 d4 d5 2 e4 de4 3 Nc3 Nf6 4 f3 Bf5 5 g4 Nd5  6 g5 Nd5  7 fxe4 Nxc3 8 bxc3 e5 9 Nf3 ed4 10 cd Bb1+   11 Bd2 Bxd2+  12 Qd2 Be4 13 Qe3 Qe7 14 Re1! 
rather than the clearly inferior 14 Kf2?

8...e5 9 Qd3 ed4 10 cxd4 c5 11 d5 Bd6 12 Bg2 00 13 Ne2 Re8 14 00 Qc7 15 Bf4! c4 16 Qd4 Be5 =

Scheerer only gives 15 Ng3? c4 16 Qf3 Nd7 "and White is strategically busted."  The critical improvement is 15 Bf4! found by my computer. For the pawn, White has a strong center, piece activity and pressure.

I believe there are other improvements in Scheerer's book, around move 12 or later, just waiting to be found.


Correction:  A) 10...Bb4+ 11 Bd2 Bd2 12 Qd2 Be4 13 Qe3 Qe7 14 Kf2 Bd5 15 Re1! Qxe3+ 16 Rxe3 Kf8 17 Bg2 Nc6 18 Rb1 Rb8 19 Ne5 Nxe5 20 Rxe5 Bxg2 21 Kxg2 c6  22 Ra5 = according to the computer.

It would certainly be helpful if Gambit, so stridently critical while posting of others' perceived errors, were to post the correct moves.
