I am Confused Ke3 or Re7+
Parent - - By BrandonSi (***) Date 2010-03-08 13:59
If you want to confuse everyone, play Ng5.. :)
Parent - - By Master Om (Bronze) Date 2010-03-08 14:06
Whats the IDEA of that ??. None of the engines suggest that. ?
Parent - - By BrandonSi (***) Date 2010-03-08 14:18
I can almost assure you it's not the best move.. Just seems like an interesting alternative.

play those moves forward and give 1 min for every move and see what happens ?

After Running for 20 mins also its not showing Ng5 ? . How come its showing in your hardware.
Parent - - By BrandonSi (***) Date 2010-03-08 15:19
Well I was using two lines of analysis. I don't think it would ever show up as the PV.

I haven't tried any other engines yet, but let me check that out.
Parent - - By Master Om (Bronze) Date 2010-03-08 16:10

With Stockfish? If you're using 1.6.3 then something might've changed in the pruning or evaluation, but I thought 1.6.3 was a bug-fix.

I don't see Ng5 here but this is just with half of a processor and some experimental build, Depth 24 must be better than this.

Ai, you are playing this, and with White :) ? Please analyse the openings yourself and not by computer :) They are hopeless in positions like this anyway and teach you nothing. Seriously it seems you have no opening advantage left. If you are Black Omprakash, by now you should see you don't need a computer to draw this... If you are White...

100% True.

Yes and....... this is my correspondence game. I wanted to play urusov gambit as i analysed that for a month but that idiot played 2......Nc3 and all doomed. :-(

This is comical, but I'm not at all sure you intended it that way Om. I never even heard of the Urusov Gambit! So I don't think I'm qualified. Lost all my games last year and not actively playing at the moment, not even a clubmember anymore as we ran out of money to pay for the clubmembership. I desperately need for the Stockfish Server to become a financial success! If we charge half of what Rybka is charging I'm sure I'll get rich! Just kidding. If I wanted to play for a win in a correspondence game, opening 2. Bc4 seems to me a risk though. You might get the Evans gambit -or something like your Urusov maybe- but if your oponent wants a "Guoco Piano" what do you do. And he got you out of book which is a moral victory if you prepared something for a month, no matter what happens next in the game :)

Oh well, I don't know openings but I do like the opening phase of the game a lot. I would take an example from Korchnoi, who must have played every opening you can think of, at least once on a very high level and still can spend quite some time in a position where you think there is only theory. There is always more! And he will just sit down in this familiar position and think about what has never been played, just to get in the right frame of mind for the game. It is also good for your instincts I think, your sense of danger gets sharpened if you just start imagining your opponent doing all sorts of dirty tricks in an opening you think you know :) But in that case, getting nervous will maybe help you in the short run but is not so good for your health in the long run. Most of this can be done in your preparation and then you do not need to watch the clock so much. Correspondence is also a great way to get more feel for the openings, and just to study some relevant games. But you have to get a feel for what you are playing, and then it doesn't matter any more what your opponent replies, because it will not be threatening any more, because you stand behind what you play. It is not some theory somebody else wants you to believe, but it is you and your own ideas. Can you imagine the psychological effects that has, even when your correspondence opponent is hundreds of kilometers away he will feel it! Even Deep Blue would get afraid of you! At least that is the theory :) You could say that studying chess is then a bit like meditation and the goal is not so much knowledge of, but feeling one with the game. Om Prakash, you are from India you should know if that makes some sense :)

Regards,
Eelco

By the way here is my new Rainbow Serpent version, it finds Ne2 quicker! Your game position is the very first it is analyzing, I just made this build 182.

100% true. I admire your points. I have played Kings Gambit,Max lange and Urusov since i am kid. i have my own analysis of those but in opening Transposition is very important. Check out for my new book i would like to share the analysis if you want. By the way whats rainbow serpent ?
Parent - - By Eelco de Groot (***) Date 2010-03-12 08:42
Thanks Om Prakash. I'm not doing much myself with openings at the moment, I would take up so much time and I only have one computer that is being used for testing program changes, there is just no time for building books. Have you written an actual book? Is it for sale? I tried to keep up with theory a little by buying books :) It is not very effective if you don't study them. Rainbow Serpent is just a private version of Stockfish, with some changes of my own and Dann Corbit's changes but nothing very spectacular. I wrote some more in the thread a while back from Buffos where he discusses one of his correspondence games. That is still an interesting testposition, I am rerunning it now http://www.talkchess.com/forum/viewtopic.php?t=33218

True. I make ctg books. Its mainly from my own analysis on unorthodox openings which i love to play . My teacher has his own set of analysis which i also study to make it repertoire.

True, I just did that in a corr game recently:

And clearly I'm not going to win :)

The opening you are playing you shouldnot have lost for sure. I am sure after black's Ne5 there is lot of things to be discovered.
Parent - - By M ANSARI (*****) Date 2010-03-11 04:48
I don't think an engine helps here, but without looking at engine analysis I would say Ne2 is best.  White should try and get rid of one of the bishops and that seems that is the best way to do it and still keep you pawn structure good.  If BxNf3 then BxBb4 and if BxBd2 then Nf3xd2.  This is also a good way to get rid of the queen pin without concessions.
Parent - By Master Om (Bronze) Date 2010-03-11 07:35
I was waiting for your views. You are one of those people who understand the double bishops advantage better than any one in this forum. (thanks to Naum 4 vs Rybka 3 matches you conducted.)

from what i am seeing Rybka 4 or whatever Vas wants to call it has not been speeded up.i am basing this on Lukas evals and although he has not replied yet regarding speed of R4..Lukas has bigger hardware than me,but on AN of this position engine X can hold its own.also i believe i did not get strongest download of the engine i was useing.

i will be interested on Majid's comments on this.
Parent - - By NATIONAL12 (Gold) Date 2010-03-11 01:33
just out of interest my eval at d30 of move Re7 is 0.53 more or less same as Lukas.

hi, Your analysis is good enough but in this tricky position i think Stockfish only understands it. It understood the Zugzwang in this position.

Now Watch the move 40. whats the idea ? . To create zugzwang type of position. In the position i posted my position is odd as i have to move. So i planned for triangulation such that in same position its black to move. Stockfish at d28 got those. I was expecting 41.....Bb2+ 43.Kd3!!! which was my move and i think that's differentiates between engine play and human interference .
