A french defence game

[Lyudmil Tsvetkov]

ok, the only way I can think of of playing couple of analysis sessions simultaneously is by playing blitz, returning the first intuitive moves that comes to mind.

maybe this will work better, after all, as otherwise I have to look at SF output, which sometimes completely derails me.

a4:

[d]rn2k2r/pp1bnpp1/4p2p/q1ppP3/P2P2P1/2P2N2/2PB1P1P/R2QKB1R b KQkq - 0 5

you might have as long a think/check as you want.

[Lyudmil Tsvetkov]

after Qa4, Qb1, while after Qa5 in the second line, Bd2

a) 7.g3!? Qa5!? 8.Bd2 Qa4 9.Qb1 o-o

b) 7.Nf3 Nbc6 8.Bd3 Qa5!? 9.Bd2 Bd7

I tell you what: show an advantage for white - nothing special just something - and I will buy your book

on your second line, after Nf3, c4:

[d]r3k2r/pp1bnppp/2n1p3/q1ppP3/2PP4/P2B1N2/2PB1PPP/R2QK2R b KQkq - 0 5

SF already says white has the advantage, so it is time to buy book.

on your first line, after g3, f4:

[d]rnb2rk1/pp2nppp/4p3/2ppP3/q2P1P2/P1P3P1/2PB3P/RQ2KBNR b KQ f3 0 5

[Lyudmil Tsvetkov]

f4, though, is no doubt the strongest continuation.

[d]rnbqk2r/pp2nppp/4p3/2ppP3/3P1P2/P1P5/2P3PP/R1BQKBNR b KQkq f3 0 2

if anyone would like to try this one, happily.

[Lyudmil Tsvetkov]

so far, for the f4 line I have:

f4 b6 Bb5 Bd7 Bd3 Ba4 Nf3 a6(to change bishops via b5 with draw) Rb1 Nd7 0-0 c4 Be2 0-0 g4:

[d]r2q1rk1/3nnppp/pp2p3/3pP3/b1pP1PP1/P1P2N2/2P1B2P/1RBQ1RK1 b - g3 0 9

and white has almost won

any suggestions for improvements for black?

[mbabigian]

Bd2 is the obvious response here, but you understand very well I can not play against everybody, simultaneously...

I totally understand. There is no rush to respond. The g4 line has moved into a branch with very little data on my end so I'm having to generate it and that takes time. Your simul I hope will teach people something anyway! I've already learned a few things, and as Carlsen says, that is what is important and keeps chess interesting. In response to Bd2, I play Bd7.

[d] rn2k2r/pp1bnpp1/4p2p/q1ppP3/3P2P1/P1P2N2/2PB1P1P/R2QKB1R w KQkq - 0 10

thanks.

I will be back, but in a couple of hours.

so far, I have never heard of a thing like simultaneous analysis, have you?

analysis tends to be much more demanding than normal games, so doing a simul there seems, I don't know what.

besides, the opponents to the person giving the simul are usually much below his level, while on this case I have to play a couple of SF instances.

not the easiest thing in the world, is it?

It is not easy at all, which will make any success that much more amazing! It is absolutely clear that the engines don't understand this variation. So this simul may help folks better understand engine shortcomings and who knows, maybe some patches will come from it.

Since I have never heard of simultaneous analysis against computer engines either, I declare "Lyudmil Tsvetkov" to hold the World Record for most simultaneously analyzed games against 3400 ELO opponents!

So just to let you know, a4 was not the top choice in my data. Rb1 and Be2 were tied for best at -0.20. a4 was 3rd at -0.33.

Since this thread is getting a bit confusing with multiple people talking to you, do you want to move this into a separate thread? I can spawn one on my next move and put a note here to reference it. I can also look at your f4 line once this is over.

hi Mike.

I guess we can continue a bit more here, maybe others will give some valuable input too.

it does not make sense to analyse any non-optimal moves, and, as I already checked it and am certain f4 is best, maybe we can just concentrate on it?

Absolutely. This is not OTB chess with touch move. This is a very complicated position and understanding the best plan is most important.

I have pointed the system at the f4 line and it is starting to work on it. There isn't enough data in this line for me to report anything until I give it a few days. Stay tuned!

[Werewolf]

after Qa4, Qb1, while after Qa5 in the second line, Bd2

a) 7.g3!? Qa5!? 8.Bd2 Qa4 9.Qb1 o-o

b) 7.Nf3 Nbc6 8.Bd3 Qa5!? 9.Bd2 Bd7

I tell you what: show an advantage for white - nothing special just something - and I will buy your book

promised?

in which of the 2 lines, or in both? ...

Yes, it's a promise and it can be in either 7.g3 or 7.Nf3 or 7.f4 (your favourite move).

You don't even have to win - just show pressure with a plan to follow up with and I'll certainly buy the book.

(I want you to do well - I hate the French!)

[Werewolf]

f4, though, is no doubt the strongest continuation.

[d]rnbqk2r/pp2nppp/4p3/2ppP3/3P1P2/P1P5/2P3PP/R1BQKBNR b KQkq f3 0 2

if anyone would like to try this one, happily.

Yeah I'll take this on for black. Just give me 24 hours to prep.


In these structures - what is your opinion of the move ...c4 for black? I think Botvinnik didn't like it because although black takes away the d3-h7 diagonal for white he loses counterplay against the centre (except by ...b5 or ...f6)

[zullil]

so far, for the f4 line I have:

f4 b6 Bb5 Bd7 Bd3 Ba4 Nf3 a6(to change bishops via b5 with draw) Rb1 Nd7 0-0 c4 Be2 0-0 g4:

[d]r2q1rk1/3nnppp/pp2p3/3pP3/b1pP1PP1/P1P2N2/2P1B2P/1RBQ1RK1 b - g3 0 9

and white has almost won

any suggestions for improvements for black?

[D] rn1qk2r/p3nppp/1p2p3/2ppP3/b2P1P2/P1PB1N2/2P3PP/R1BQK2R b KQkq - 5 10

Well, asmFish is not fond of 10... a6 here. It believes that the three best choices here are c4, Qd7 and Nbc6, all of which leave Black with a tiny edge. Of course, 5 hours of searching to depth 58 might not compensate for asmFish's lack of understanding of chess.
