Re: Move 4

Post by LucenaTheLucid »

I would like to just chime in...it has been a while since I've been here on these forums this game vs. H8 forums has inspired me. While I might not be able to vote everyday on moves, I will be sure that if I do vote I will have some explanation with it as I am a very weak player and rely much on computer assisstance.



New position

1...Nf6 [1...Bb4 2.Ndb5 Qb6 (2...Nf6 3.e5 Ne4 4.Qg4 g6) 3.Be3] 2.Bd3 [2.e5 Ne4 (2...Nd5 3.Ne4 (3.Nxd5 Bxd5; 3.Bd2 Nc6) 3...Nb4 4.Nd6+ Bxd6 5.exd6 Qh4; 3.Nxe4 Bxe4] 2...Bb4 [2...Bc5 3.Nb3 Bb4 4.e5] 3.0-0 Line

my vote is for Nf6. To which I believe white's best response would be Bd3.

I think our best chance to compensate is via Nf6, though a6 may objectively be better, atleast more solid.

5.-, Bc5 - how about a reply like 6. Be3? The threat is 7. Nxe6, so the bishop have to move again, probably back to f8 (with no developement), or capture on d4 after which we have a problem on g7 and no developement except Bb7.
I don't see that Black has time for the g6-Bg7 manouvre, White plays on with the Ndb7 plan.

Hi Luis,

You're very welcome - nice initiative ! :D

This way of playing is rather new to me too, but I couldn't let it go this time. I have the feeling that one can get addicted in time... ;)

Thanks all it takes is time I suppose. I did not see a6 before. It is very easy to get lost in all the variations :!: However I must retire for the night.

Here is some more fat to chew on:

New position

1.Bd3 a6 [1...Bb4 2.0-0 Bxc3 (2...d6 3.Bg5 0-0 4.Ncb5 (4.Na4 Nc6 5.Nb3 Ne5 6.Bxf6 gxf6 7.a3 Ba5 8.f4 Nxd3 9.Nxa5 Qxa5 10.cxd3) 4...a6 5.c3 Bc5 6.b4 axb5 7.bxc5 dxc5; 3.bxc3 Bxe4 4.Nb5] 2.e5 Nd5 3.Nxd5 Bxd5 4.0-0 Nc6 5.Nxc6 Bxc6 Line

If Nf6 is Bg5 a troublesome move?, maybe not because Qa5. I am thinking if Bc5 Be3, Qb6, if Na4 Qa5 +

But what we have after Nf6, Bd3?

I'm not saying black is winning (yet), but if there is no real good plan, then I would vote .....a6 as a regretale necesity, and is slow, but so are other things.

We shouldn't have played c5?

.

We would have needed to contend with different problems. Did you see something clearly better than c5?

Maybe an earlier move was wrong. Maybe the missing pawn was anyway wrong.

Perhaps there should have been extensive analysis before the first black move. (this could be done eg by rybka, and by trying a move or two and analyzing from that point, in different variations so that the computer is analyzing from closer up [ie advanced chess]).

Earlier move - Bb7 seems kind of obvious. I think Nf6 instead of c5 was proposed.

It was, but was outvoted.
And now it's past, and Black is far from beaten.

I favour Nf6 with a slight marging over a6 here. Other moves I don't like so far.
