{Draw agreed.} 1/2 - 1/2
24h/move as a guideline but overstepping time limit doesn't mean time forfeit.
Deleted is restricted to only Rybka 3 under Deep Position Analysis for 30 minutes.
Vytron is restricted to only Rybka 3's Infinite Analysis for 46 minutes 20 seconds.
(we're free to play with Rybka parameters, etc.)
Deleted will be using a DPA optimized book so this experiment will be interesting.
Your move, good luck!

1.b3? You call that optimized? 
Sure! Optimized for a quiet game where DPA will not be outsearched (I hope).

Has white ever won with b3? :)
Alan is #1 world expert in 1.b3, I wish I was having as much fun as Vempele instead of being afraid of, you know, giving him a book-win. I'm glad this will only last 10 halfmoves...
Ye of little faith... Just watch the game!
The "book" here is Nf3, in both Aquarium/Rybka and other master game d/b, but there a few games out there where white wins with g3 and c4.
The book here is what Alan plays, and that is probably going to be f4.
Lol, you knew what I was going to play before I did. I looked carefully at 4.Nf3, 4.d4, and 4.c4. Each of these moves had a much higher probability of leaving me hanging off a cliff on move 11 in positions not navigable with 30 minutes of Rybka DPA. But 4.f4 can lead to interesting positions, so all is not lost.
> you knew what I was going to play before I did
Exactly why we're so good. (Anyway that's what I want people to think so they'll freak out and play some really stupid variation that leads them straight into a lost position.)
I just looked at your most recent games and saw you've been toying with f4 with reasonably good results. Combined with your prep, and the opponent's lack of prep in this kind of rare line, it just made good sense. I see six playable black moves now and a seventh just outside my acceptable range. I won't say what black move I'd make but my general strategy here, with so many near-equal choices, would be to drive you out of book quickly.

Throttle him Alan. :)
Deleted is Alan, otherwise known as the B3 expert?
Alan Sassler = Alan = Deleted. Notorious Las Vegas socialite and man about town. Well known in DoD circles. Featured in Dos Equis "Most Interesting Man in the World" commercials. Look for the upcoming Playboy interview and feature in the Washington Post Style section. Alan is the only guy in this forum that exceeds Vas in terms of coolness. He's so cool he can play 1.b3 and not sweat it, and believe me, that is cooler than the South Pole.

i thought of giving a comment but couldnt decide whichone:
- will he keep cool after reading that?
- you know... i prefer women. but thanks anyway.
- hey guys, i can play 2.b3 and not sweat it.
- wheres information about his opponent?
- what is DoD?
- why was he deleted then? too bad.
so i just posted them all ;P

DoD = Department of Defense. The Pentagon.

Nowhere, I AM top secret information
> - why was he deleted then? too bad.
Nobody knows, he deleted himself! (and could undelete himself if he wanted, by changing his name back to Alan, so it looks like he wants to remain Deleted.)
Heck, if he changed back to Alan everybody would take a week or so to used to the new nick!
I'll assume this is an inside joke. Personally, I've have never heard of him, but I am interested in his comments on DPA.
> I'll assume this is an inside joke.
Keep a close look at his posts :)
> I'll assume this is an inside joke.
Keep a close look at his (Alan's) posts :)
Now, this is interesting, if DPA wins it could mean that it's a sound automated analysis method if you are well prepared on your variation (and I know you are...)

Decision point 1:
3.e3
(This leads to more closed positions than 3.g3, 3.Nf3, or 3.f4)

OK, I had an unforeseen problem. Normally, I would play Nf3 here. But this leads to a slow development game where I will be in a precarious position when I start DPA on move 11. I tested to see how Rybka would handle some possible positions with 30 minutes of DPA, and the results were disturbing. To avoid this fate, I've decided to play:
4.f4
This will certainly not lead to the closed position that I was looking for, but it forces the important opening choices into the first 10 moves (I hope). Kudos to Vytron if he played 1...d5 to minimize the impact of a short opening book. On the bright side, the selected move should be more likely to provide a decisive result, one way or the other.

I think we had a misunderstanding, I proposed to remain on book for 10 halfmoves (5 moves), not 10 moves, just like in the canceled v titanium cranium game.
But I should certainly say that I don't have enough theory on this position to rely on it, that would put me out of book, so what do we do? Do I turn on the engine already? Do I use interactive IA until move 10? Do you just pick black moves until move 10? (this being more an experiment than competition, I'd trust you'd pick black's best moves) Something else?
OK, my fault. We can start the experiment on move 6, per your original plan. Normally white would be looking at either mounting a kingside pawn storm, weakening black's queenside pawn structure, or opening and controlling the f file. I suspect that Rybka will choose none of the above, but it should be amusing and maybe enlightening anyway.
There are at least a half-dozen equally good moves right here. I wouldn't lead you astray, you don't need theory right now, though if you must have something to go on try seeing if you can transpose into a better-theorized line. Play a move and see what happens.
> There are at least a half-dozen equally good moves right here.
Ok, thanks.
sorry for the ignorant question, but what is 'deep position analysis'? ie what IDeA used to be known as? or the chessbase feature? i'm confused. seems like an interesting experiment at any rate.
DPA is a Chessbase tree search option where you get to choose the branching factor in the first four plies, a pruning evaluation, the length of variations, and a few other things. It results in a tree that's wider and not as deep.
Then, shouldn't it be called Wide Position Analysis? Who's program is it?
It is implemented in every Chessbase GUI since F7 (maybe earlier). Wide Position Analysis doesn't get the bull off the ice.
> Wide Position Analysis doesn't get the bull off the ice.
:-D
Wide Position Analysis doesn't get the bull off the ice, means?
When you analyze with Chessbase products in verbose mode, your games are annotated with this kind of useful information.
> When you analyze with Chessbase products in verbose mode, your games are annotated with this kind of useful information.
Except that it still doesn't tell you what the heck it means!
Especially for a non-English speaker!
I thought it was an idiom but after searching on Google... it only shows instances of Chessbase or related saying it...
Yea, I did a little searching but never could really fiqure it out either. I've heard of cows pissing on flat rocks, etc, etc, but the bull on ice escapes me. Maybe I don't have a good enough sense of humor...<roflmao>
Although I did see on tv once a deer (female persuasion of course) stuck on a frozen pond somewhere up north, that had to be helped off of the ice... Maybe that's it?
Perhaps it's a German idiom.

this is a fun experiment. i would think deleted is in a lot of trouble but i haven't tried the DPA feature in chessbase yet. deleted, what settings do you use?
btw, i just ran IA from this position & rybka gives a shite position for white @ d20. it will be interesting to see if DPA does better.

If Deleted is able to find a position in where DPA outperforms IA in his first try (in some obscure line!) it would mean chess is full of them.
