Those threads are where I picked up the ideas - thanks to Brabo for sharing many moons ago!  Grin

8.Rc1 is still not well known it seems. We have discussed it already twice on chesspub see a first time in 2012: http://www.chesspub.com/cgi-bin/chess/YaBB.pl?num=1267504014/30
once more in 2016: http://www.chesspub.com/cgi-bin/chess/YaBB.pl?num=1444067885

Mea culpa! Yes, I saw this discussion at the time, but then as you can tell forgot all about it! What with this and Tony's line it's not looking good for 5 ...g6. A pity!

Can you help, Tony?

I dunno! But I wasn't all that excited about Black's prospects after 8.Rc1 O-O 9.b3 dxe5 10.fxe5 c5 11.d5 Bc8 12.Be2!? N6d7 13.Nf3 Nxe5 14.Nxe5 Bxe5 15.Bxc5 Qc7 16.Bd4 Bxh2 17.Qd2!. I spent quite a few hours a few nights ago taking a look at this line and the alternatives for both sides. Even if Black survives here, do you want to play this in an OTB game 6 months from now when you can't remember what you're supposed to do?  Cheesy

Meanwhile in the 8 d5 line, wasn't 10 ... c6 (what else?) played yonks ago by Sergeev, who I thought had pioneered the system?

Yes:



I hope someone can repair this one - I would really rather play the Sergeev variation over the standard main line of the 4PA.

I imagine White could have some way of deliberately jettisoning a central pawn for attack/initiative, though I don't immediately see it (and it might not accord with spending a tempo on Rc1). Can you help, Tony?

Doesn't seem all that relevant given Black's problems in the 8.Rc1 variation.

1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. c4 Nb6 5. f4 g6 6. Nc3 Bg7 7. Be3 Be6 8. d5 Bc8
9. Nf3 O-O 10. Be2 c6 11. O-O Bg4 12. Qd2 cxd5
As far as I can see, 10. - c6 is a new move and Black has no problems.

Since you're talking about move 9 alternatives, may I ask what's the current theoretical verdict on 9...Bg4?


A game today on this line. Both players have EL= greater than 2600 and Kovalenko is one of the few players over 2600 that "sometimes" plays the Alekhine
(others are Rozentalis, more often with also a game given below, and Shimanov - less often)

I must confess I was never atracted to 9...Bg4 but
apprently is a frequent choice of GMs (although they lose).
The game today uses a move criticized by G. Jones,
16...g6, in his analysis of the game Bologan-Rozentalis. I saw the game and apparently Black was Ok and it is not clear where it went wrong.



Onischuk,Vladimir (2591) - Kovalenko,Igor (2643) [B03]
Russian Cup Final 2013 Khanty-Mansyisk (1.1), 12.12.2013
[Robot 4]

1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.f4 dxe5 6.fxe5 Nc6 7.Be3 Bf5 8.Nc3 e6 9.Nf3 Bg4 10.Be2 Bxf3 11.gxf3 Qh4+ 12.Bf2 Qf4 13.c5 Nd5 14.Nxd5 exd5 15.Qd2 Qxd2+ 16.Kxd2 g6 17.f4 Bh6 18.Be3 f6 19.h4 0-0 20.h5 fxe5 21.fxe5 Bxe3+ 22.Kxe3 g5 23.h6 Rf4 24.Rag1 Re4+ 25.Kd2 Nxd4 26.Rxg5+ Kh8 27.Bg4 Rg8 28.Rxg8+ Kxg8 29.Bc8 Nf3+ 30.Kd1 Nxe5 31.Bxb7 Rd4+ 32.Ke2 Kf7 33.Rg1 Ng6 34.a3 Kf6 35.b4 Rh4 36.Rf1+ Ke6 37.Bc8+ Ke7 38.Bb7 d4 39.Rh1 Rg4 40.Bf3 Rf4 41.Bd5 Rg4 42.Kd2 Ne5 43.Rf1 Rg5 44.a4 Rh5 45.Rh1 Rxh1 46.Bxh1 Kf6 47.a5 c6 48.Be4 Kg5 49.b5 cxb5 50.c6 Kxh6 51.c7 Nc4+ 52.Kd3 Nd6 53.Kxd4 Kg7 54.Kc5 Nc8 55.Bb7 Ne7 1-0

Rozentalis also played the Alekhine, Luther against
him played the 4PA, this time 9...Be7.
Here is the game

Thanks

somehow, i recall seeing that someone mentions 8...Bc8 as the "safe" and normal continuation but
also mentioning the wild 8...Bf5 with no analysis;
that is why i asked

also I know that this site keeps several nice pieces of analysis (which in some cases are completely ignored by the site comentators - see, e.g., the last post by Paddy on the voroznev). And not sure whether this
line has not been here analised before

Here is the game "translated" :



I think 8...Bc8 is more usual. And maybe more safe. Perhaps  another story of a rating favourite who needs to play for a win...?

Interesting game though, and sorry I dont know nothing about this piece sacrifice...

Why do you assume the moves which lead to position 1 (Reply #2 by Dimis) are correct? Last year I already posted a link to my blog which presents new ideas for white: http://schaken-brabo.blogspot.be/2012/12/aljechin-met-g6.html
