I am sure you are right….although two articles I have by Gerard Welling would tend to suggest there is scope for some investigation (and or improvement) on what you have given.

Not easy to cure the Alapin, but of course you can try. 7...Nge7 was my latest attempt, the line 7...d5 has other problems. Gerard's articles are great, because he considers many original analyses by Alapin. Very motivating for anyone with an interest in chess history. I have also studied the "large Alapin" 3...a6 4.Ba4 Bb4" and the "extra large Alapin XL" 3...a6 4.Ba4 b5 5.Bb3 Bb4!?, the topic is really too "large" for a debate on chesspub.  Smiley


How about 
1.e4 e5 2.Nf3 Nc6 3.Bb5 Bb4 4.c3 Ba5 5.Qa4 Nge7!?

I think white is better, but black is not lost yet.

Edit: The sentence about 7...d5 was nonsense.

Ametanoitos, your Marshall recommendation is excellent. Of course a draw should still be possible, but it is a hard nut. 

Silicon believes it can hold the draw. But it is painful to watch, and I think in practice White should just be fine.

What do you think about 3...Bb4

Discussed in Bernhard Lach: Spanisch - Die Alapin-Variante 1.e4 e5 2.Sf3 Sc6 3.Lb5 Lb4! from 1995

Slightly worse than 3...Rb8.

I have changed my mind. 3...Bb4 seems at least as good as 3...Rb8.

Really? Alapin's Attack is perfectly playable.

Actually I agree with this. For the purpose of this thread it doesn´t make so much sense trying to analyse anything until a definite conclusion can be made.

15.Re4 g5 16.Qf1 looks like a decent choice for White and it´s fair to conclude it is somewhere between += and =.

The next line of interest to me is 8.c3 d5 9.exd5 Nxd5 10.Nxe5 Nxe5 11.Rxe5 Bb7 instead of 11... c6.

Then critical looks 12.Qf3 Bd6 13.Bxd5 (not 13.Rxd5? Re8!) c6 14.Re2 cxd5 15.d4 Qc7 16.g3, but despite the good practical results for White Black seems to have decent play with 16... Rae8 17.Nd2 b4 18.cxb4 Qc2 as in Anand-Short, Manila 1992.

So probably 12.d4 should be played when both 12... Qd7 and 12... Bf6 are good moves to my limited knowledge. I haven´t looked any further yet.

Is there a way to a slight advantage for White?


I hope so! Though with some risk white has to take..  Wink



14.Na3!? is the move I lay upon in my main line.  Cheesy

All I can say is that this line of yours is good for our Spanish repertoire.  Cool
Of course, I can oppose to you and enter into a long analysis after your last move of the line.. But it would be a waste of time to try to convince you that black can draw with fine play. After all, our main point is to create a repertoire for white trying to achieve at least +=/=..  Wink

Honestly I would find it amazing if White can leave the development of his queenside aside with 19.a4 without Black at least being able to generate enough counterplay.

There is a lot to explore here and as you observed only deep analysis will allow a reasonable assessment. I wonder if a top practitioner of the Marshall like e.g. Peter Leko already has a solution for this on is PC.

In your line after 23.Qxc1 Bf4 doesn´t look so clear to me and a move like 19... f5 also has to be analysed despite the initial bad assessment of the computer.

16. Qf1 Qxf1+ 17. Kxf1 Bf5 18. Nd2 Rad8 19. f3 Bxe4 20. fxe4 Nc7 21. a4! is Vigorito's main line and this is better for White. You can call it unclear, and definately in practice all 3 results are possible in sub-GM level, but i cannot but feel more comfortable with White.

After 17.f3 Bh3 18.Qf2 Qg6!?N i cannot disagree with your (excellent as it seems) "human eye" and indeed the variation you give is promising for Black (i think). Without deep analysis i cannot say something with confidence, but when i reached this position after inserting the moves in my PC, i tried the move 19.a4. I thought that Black threatens nothing at present and i don't really know if i need the Knight at d2 yet. Maybe Re2+Bc2 is an idea, i don't know. In any case Houdini gave 19...b4 20.c4 and now i investigated 20...Nf4 a bit. After some trial and error, i found that 21.c5! Nd3 22.Qc2 Nxc1 23.Qxc1 is in White's favour. So, yes, sorry if i underestimated the 17...Bh3 move but still i haven't seen any problems for White.

-> 17.f3 Bh3 18.Qf2 is +/=


Then something like 18... Qg6 19.Nd2 f5 20.Re1 Rae8 21.Nf1 Rxe1 22.Qxe1 f4 seems to give Black reasonable play, at least to my human eye.

As for 16...Qxf1 i always thought that it was considered "+/=" anyway. Anyone else has a different opinion?


You have cited Vigorito before and he concludes that it leads to an unclear endgame.

-> 17.f3 Bh3 18.Qf2 is +/=

-> 16...Qh6?! was Pavlovic's recommendation which is met strongly by 17.Re1! Kh8 (given by Pavlovic) 18.Bxd5! (18.c4 is good as well) 18...cxd5 19.Qg2 Bb7 (and not 19...Be6 because of 20.h4! After 19...Bb7 20.h4?! is met by 20...Rae8! with enough play for Black, i think) 20.Nd2 f5 21.Nf3 f4 and now 22.Bd2 is the simplest with an undisputed advantage for White.

Note that 16...Qh5 17.Re1? is bad due to 17...Bh3! but after 16...Qh6?! 17.Re1 Bh3? is met by 18.Bxg5!

As for 16...Qxf1 i always thought that it was considered "+/=" anyway. Anyone else has a different opinion? 

Time to move on?  Wink
