@Inn2,

Sorry for the delay. I agree with your statement except for the reply to 7.Qg4 g6(still alive) 8.a3 Bxc3 9.bxc3 Nxc3 10.Bd3 Nc6 11.h4 Ne7 12.h5 g5 13.f3 c5(best not Bd7) 14.dxc5 Nc6 15.Bd2 f5(not d4) 16.exf6 Qxf6 16.Bg6+ with chances for both side.
                                                       15.f4 Qa5(not f5) with chances for both side.  This is the lines I like against 6.Be3 Ne4.

Best regards

Hello,  any change in opinions after one year?  Wink i've had occasion to look at the Mac again..

@Memers

GM Finkel in CBM106 concludes that 6. Be3 gives excellent chances for an advantage, "in nearly all the lines Black experiences serious problems in the opening". Both Finkel and McDonald (on Chesspub ebooks) are largely agreed on which games constitute the critical lines but they assess them differently:

In line with 6. Be3 Ne4 7. Qg4 g5: critical game is Belov-Alavkin Sochi 2004 (the famous Shirov-Volkov is probably not best play for White) where Finkel thinks White is just winning after 24. Kd2!, while McDonald says Black has compensation. I guess the truth is somewhere in between.. Black probably has enough compensation to play OTB but not in correspondence! Finkel also likes 15. Ng5 for White.

7. Qg4 Kf8: the Goloschapov games are fairly devastating for Black, so both Finkel and McDonald  seem to agree that delaying the opening of the centre is the better path: 8. a3 Bxc3 9. bxc3 Nxc3 10. Bd3 Nc6!? as in Kurnosov-Volkov. Finkel gives a number of improvements on White's play (e.g.11. h4), and considers White's attacking prospects to outweigh the lack of a pawn, while McDonald just seems enthusiastic on Black's chances (not much analysis given). 

Have not looked at 7... g6 yet, but both Finkel and McDonald seem to agree that line given in Smirnov-Alavkin Sochi 2004 give White excellent chances for a win (not just an edge!).

It looks like the greedy 7... Qg4 Kf8 8. a3 Bxc3 9. bxc3 Nxc3 10. Bd3 Nc6!? is the only way left to go.

Hello;

1. I, also agree with majority. Both main lines, 7.Qg4 g6 and 7.Qg4 Kf8(Coffin Rook), are in dire strait. I, like HgMan, have scuttled toward 7.Qg4 g5!?.
2. I noticed that CBM 106 have an opening section on 6.Be3, what is GM Finkel's conclusions?? and does he analyze 7.Qg4 g5 in depth?? Specifically that fascinating, out of box, and anti-computer game of GM Shirov-GM Volkov 2003?? The game is given below.

Shirov,A (2730) - Volkov,S (2620) [C12]
ECC, Rethymnon GRE (2), 2003
1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 5.e5 h6 6.Be3 Ne4 7.Qg4 g5 8.h4 h5 9.hxg5 hxg4 10.Rxh8+ Bf8 11.Nxe4 dxe4 12.Ne2 c5 13.0–0–0 Qa5 14.Nc3 cxd4 15.Bxd4 Nc6 16.Nxe4 Nxd4 ½–½

Thanks

I'm not ready to give up on the MacCutcheon yet, but there do seem to be a number of stumbling blocks, especially after 6 Be3.  I still prefer 7 ... Kf8 to 7 ... g6, but am warming to the less orthodox 7 ... g5, which I have tried against 6 Bc1 (see other thread).  I suspect it might also work here, though I have yet to try it out.  If I get a chance this weekend, I will post some analysis for conversation...

I started this thread suspecting black has problems. And I still do! Embarrassed Even if black is theoretically okay, the problem is White's position is practically easier OTB.

You can get mine, for what it's worth: yes, but it is not certain, that White can prove an advantage in all lines.

Is there any verdict available on the current status of the Be3-McCutcheon ? Black having problems?

18 ... Qd7 ?  That eliminates the lost tempo from the the queen on e7, but Black appears to be on shaky ground.  Is there an improvement earlier?  I wonder if Black might avoid the pawn strikes on the kingside?

Sorry.  18 ... Qe7 loses out to 19 Nxg5 hxg5 20 Bxg5.  Back to the drawing board, I suppose.  Undecided

In this recent game with Fressinet, Libiszewski seems to have improved on Volkov's play against Goloshchapov with 13 ... Bd7, which appears to be a novelty.  White wins, but as far as I can tell the position looks sharp, difficult, but reasonable for Black after 17 ... g5.  I don't like 18 ... Bf7; 18 ... Qe7 looks safer.

[Site "Noyon"]
[Date "2005.03.31"]
[White "Fressinet,Laurent"]
[Black "Libiszewski,Fabien"]
1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 5.e5 h6 6.Be3 Ne4 7.Qg4 Kf8 8.a3 Bxc3+ 9.bxc3 c5 10.Bd3 Nxc3 11.dxc5 Nc6 12.Nf3 f5 13.Qh5 Bd7 14.g4 Be8 15.Qh3 d4 16.Bf4 fxg4 17.Qxg4 g5 18.Rg1 Bf7 19.h4 gxf4 20.Qg7+ Ke7 21.Qf6+ Kd7 22.Qxf7+ Qe7 23.Qxe7+ Nxe7 24.Nxd4 Rac8 25.Nb3 Rcg8 26.Kd2 Ned5 27.Nd4 h5 28.Rg5 Rxg5 29.hxg5 h4 30.g6 h3 31.Rh1 Ke7 32.c6 bxc6 33.Nxc6+ Kf8 34.Nd4 Ke7 35.Nc6+ Kf8 36.Nxa7 Rh5 37.Nc6 Rg5 38.Nb4  1-0

I'd want to play around with this line a little before testing it, but this looks like an important improvement for Black.  I still have some reservations about 13 exf6, which looks strong, too.

So memers is right, I mixed up the two move orders.

Hello;


Guadalpi,D (2315) - Vallin,G (2356) [C12] 
FRAchT Nat1 (5.5), 2002 
 
1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 5.e5 h6 6.Be3 Ne4 7.Qg4 Kf8 8.a3 Bxc3+ 9.bxc3 Nxc3 10.Bd3 c5 11.dxc5 Nc6 12.Nf3 f5 13.exf6 Qxf6 14.Qh5 e5 15.Bg6 Be6 
Black wants to win; after 15...Kg8 White can force a draw with 16.Bg5. 
 
16.o-o Kg8! 
Black is facing problems after 16...Bf7?! 17.Nh4 Rae8 18.Bd2! see above.

To Mnb;

1. Don't you mean the other way? 15....Kg8!,the right move order, as 15....Be6 allows white to play the drawish endgame with 16.Bg5 Bg4. After 16.0-0 Be6 the game gets back to your quoted game and analysis.

2. IMO, this actually should be the right move order. Now, 17.Rae1, black can force a draw with 17....Ne7. The other  moves are 17....Rd8(Fressinet-Vallejo Pons, 2000) and 17.....Bf7(probably main) 18.Nh4 Re8 transposing back to Lanka-Morozevich 1998). Here, instead of 19.f3, white should play 19.Bd2 Ne4 20.Bc1 completing deveopment of his pieces and offering the c5 pawn. I believe this is the critical postion in this variation.

3. There may be holes in the above variation, but I recommed black should take the draw at 17.Rae1 Ne7=

4. I'm curious, how do you highlite and put the previous postings in the white square ?? As you can see from this posting, I just cut and paste. Overall, this method looks clumsy.

Have a nice one!!

FRAchT Nat1 (5.5), 2002

1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 5.e5 h6 6.Be3 Ne4 7.Qg4 Kf8 8.a3 Bxc3+ 9.bxc3 Nxc3 10.Bd3 c5 11.dxc5 Nc6 12.Nf3 f5 13.exf6 Qxf6 14.Qh5 e5 15.Bg6 Kg8
Black wants to win; after 15...Be6 16.Bg5 White can force a draw with 16.Bg5.

16.o-o Be617.Nh4
Deviations are analysed by Finkel.
17.Rfe1 Rf8 (that is Black's idea) 18.Bd2 e4 19.Bxc3 Qxc3 20.Nh4 Qxc2 -+.
17.Bd2 Ne4! 18.Bxe4 (Fritz gives 18.c4, but I do not trust it after Nxc5 19.cxd5 Bxd5 20.Nh4 Bc4) dxe4 19.Nh4 Kh7! threatening g7-g5.
17.Rae1 Bf7 18.Nh4 Rae8 transposes to lines investigated in previous posts. If White avoids this with 18.Bxf7+ Qxf7 19.Qxf7+ Kxf7 20.Nxe5 Nxe5 21.Bd4 then Black has the choice between Nb5 and Nc4; because of the passed pawn on 17 White should be glad to draw. Moreover Nxf3+ is interesting.

17...Rf8 18.Rae1 d4 19.Bd2 Bc4 20.Bd3 Bf7 21.Bg6 Bc4 22.Bd3 Bf7 23.Bg6 Bc4 ½-½

I have adapted this post because of the next one by memers.

Incidentally, 18 f4! in the mainline looks very persuasive as well.
