Sep-21-10  bayowulf: Well, there is no current position - I have a huge minimaxed tree starting with 10 Bf4 and it pretty much already includes most of the lines mentioned so far that people have been working on. I have been going thru lines posted in the other engine room and comparing them to what I already have. In cases of deviations I add the new position to the analysis queue and check back later.

But what I can do is post the best play I have discovered so far.

62383 positions down stream from 10.. Bb7 Minimaxed at +0.15

10. Bb7 Ne5

and then equal are two lines that transpose to the each other:

a. 11..Rc8 12. Nc3 b5 13. c5 Nxe5 14. Bxe5 Nd7 15. Bf4 e5 16. dxe5 Nxc5 *

b. 11..Nh5 (there are a lot of equal subbranches that I am going to ignore for this example) 12. Be3 Nhf6 13. Bf4 Rc8 14. Nc3 b5 15. c5 Nxe5 16. Bxe5 Nd7 17. Bf4 e5 18. dxe5 Nxc5 *

I just got Aquarium and am still learning how to use it. I am using this game as a means to validate it.

Sep-21-10  bayowulf: < WinKing: Another idea <kutz> is if one of the Rybka analysts knows how to use 'IDeA' with Rybka. You need a really fast computer for this though. <Dionyseus> was a master at using this feature of Rybka. Many variations come up that infinite analysis misses. Just a thought.>

Thats what I am doing per my previous post above - but I don't have much experience with tweaking the settings yet. I am not just using Rybka - I am also using other engines to add variety. I am concurrently using three Rybka engines and also one each of Fire, Critter and Robblito.

Sep-21-10  bayowulf: Just swapped out one Rybka engine for a Houdini. :)

I have played around with it myself <bayowulf> but am not very proficient with 'IDeA'. There may be some help for you in my forum though. Go to page 1 of my forum & read the posts <Dionyseus> sent me. They may be of some help to you. :)

Sep-21-10  Kinghunt: You can add me to the list of computer analysts too, I guess. I primarily use Houdini, although I also use Stockfish to get a second opinion on some of my lines. I don't have particularly strong hardware though. All my analysis is done on my laptop, which, while decently strong for a laptop, is still only a laptop. I have a 2.0 Ghz Intel Duo CPU T6400 with 4GB of RAM, running a 64 bit operating system.

So what is the pros and cons of 11.Nbd2?

Pluses -
1.It supports the c4 pawn along with the Queen.
2.It also supports the the possible move of e4.
3.Has the option of going to b3 which is useful to help fight for the c5 square.

Negatives -
1.It blocks the rooks direct support of the d4 pawn
2.It blocks the retreat of the bishop to d2 or d1, leaving only e3 as a retreat square.

Depth 13:1/56 from move 15 on hiarcs eval is +0.08

But sliding along this line to move 18. I get <18...Qe7 19.e3 Rfd8 20.Nd4 Bg5 21.b3 f6 22.Bf4 Ncf4 23.Qxb7 Nh3 24.Kf1 Rc7> and the eval is =0.00 is of no benefit to white. Equal.

I think this forum is a good place for you to post your IDeA lines. Please continue to do so.

If you want to contribute Houdini analysis here, I can switch to Stockfish.

Judging from the diagrams & the analysis shown I can not recommend the line <10...Bb7 11.b3 c5!?>. White would IMO have no more than a draw & may in some lines be struggling for equality. Blacks position is solid in both of the above examples.

Sep-22-10  frogbert: winking, interesting first page of your forum! like bayowulf i'm toying with "idea" in aquarium at the moment, and i in particular am interested in the possibility of restricting the moves that the engine(s) spend time on as this often seems easier than "forcing" specific content into the hash.

[my experience is that engines sometimes are very "slow to learn" that a specific move needs to be played - typically because it depends on eveluating a line "too deeply", so that one with "normal" approaches can't keep that result in the hash while at the same time exploring alternative moves earlier in the game. also, if the hash becomes too big, it tends to stop being useful.]

for the time being i can't commit to much organized engine analysis, but i might step in at some later point in the game.

Sep-22-10  WinKing: <frogbert:for the time being i can't commit to much organized engine analysis, but i might step in at some later point in the game.>

Yes 'IDeA' does need you to be committed to it. You have to keep constantly feeding it lines. But like a garden with proper care it will give you a nice return. You will receive information that regular engine runs won't give you.

Well I hope you stick around with us as we sure need your help in this game. :)

Sep-22-10  blue wave: <8. = (0.00): 11.Nbd2 c5 12.dxc5 Bxc5 13.Nb3 Be7 14.cxd5 Nxd5 15.Bd2 Qc8 16.Rdc1 Rd8 17.Qe4 Qb8 18.Nbd4 N5f6 19.Qh4 Nc5> this is your work that I started to slide along with hiarcs 12.1

Sep-22-10  goslinga: 10. ...Bb7 11. Nbd2

Analysis by Rybka 3 on an older machine:

1. (0.00) 11. ...c5 12. dc5 Bc5 13. cd5 Rc8 14. Qd3 Nd5 15 Ne4 Be7 16 Qd2 N7f6 (or Bb4 repeating moves)

2. (0.11) 11. ...Nh5 12. Be3 Nhf6 13. Rc1 Rc8 14. Qd3 Ng4 15 Bf4 g6

3. (0.11) 11. ...Nh5 12. Be3 Nhf6 13. a3 c5 14. Rac1

4. (0.15) 11. ...Rc8 12. e4 Nh5 13. Be3 Nhf6

Summary: Nbd2 is hardly sufficient for equality after 11. ...c5. There are some chances if the opponent is eager to try the 11. ...Nh5 or even better the 11. ...Rc8 variation. Also as one poster pointed out, the N on d2 blocks the sometimes useful retreat of the B to c1 to prepare for it being redeployed on b2.

I have lost faith in this line and will spend my cycles elsewhere.

Sep-22-10  blue wave: <goslinga> have to agree with your post. Nice work. I'm starting to feel the same way too. I might try to do a little more checking on 11...c5 12.dxc5 Bxc5 <13.Nb3> but I think its still only equality.

Sep-22-10  bayowulf: IDeA analysis report for today. I think my head is going to expode.

I have discovered today that navigating thru the tree IDeA I found myself going in loops, repeating the same position over and over. Apparently the tree contains looped paths - something I would not have guessed beforhand. It may also reflect convergence of lines.

What I am to do here is present plausible lines starting from 10. Bf4 Bb7 11.Ne5 11..Nh5 ( 11..Rc8 transposes)

Sep-22-10  bayowulf: OMG! This takes too much time to wade thru the tree and create a kibitz. I don't think I will do any more of this except to respond to specific positions when the debate about the next move heats up.
Sep-23-10  blue wave: <11.Nbd2> c5 12.dxc5 Bxc5 13.Nb3 Be7 14.cxd5 Rc8 15.Qd3 Nxd5 16.e4 N5f6 17.Nh4 Qe8 18.Rdc1 Nc5 19.Nxc5 Bxc5 20.e5 Nd5 21.Bxd5 exd5

d=12:1/38 -0.36 for black. or +0.36 for white.

So it seems the move of 13.Nb3 keeps white in the game.
