I think we should consider this move:

20w Ec5w De1n Me3e De2w

coz it is doing three things:

1) threaten the camel hostage
2) defending c3 trap
3) further activating the camel

Also keep in mind 20b mb3n rc3w mb4e mc4s.  This threatens to take a cat and chessandgo probably can't afford the cat trade.  Yet for him to protect c3 again he has to push our rabbit away from the trap.  In other words, we effectively un-frame our rabbit with that move.  That doesn't mean it is good, just that it is a possibility to be reckoned with.

Nice one, camelback.  That is the most readable text board I've seen yet.  You have inspired me to try to do one better:

Since we're looking at different textual boards, here's what I use with my bots:
20w
+-----------------+
8| r r r . . r r r |
7| . . c d c d r . |
6| . . x . . x h . |
5| h . E . . . . R |

3| H m r e M x H . |
2| . R C . . C . . |
1| R R R . D R R R |
+-----------------+
  a b c d e f g h

It's just the official long representation but with empty places replaced by .'s. Let's me easily have the bots parse it back in but is a lot easier, especially with mostly empty boards, to see where pieces are exactly.

WOW  :o amazing.. You guys just stole the thunder, elaborate and perfect. I think with The_Jeh's board we don't even need animal representation  ;)

I generated the board using a perl script. It was my first perl  script ;D I had to replace the empty spaces with something to prevent forum messing up the board. '.'s are nice idea.
Of course janzert's board is generated from some script. But I can see Fritzlein and Jeh spent lots of time personalizing the board. Hat's off to you  :)

Well, I'm going way offline "move 20", I shut up  :-X

I feel compelled to point out however, that The_Jeh would probably prefer a correct board!

20b Me3n ed3e rc3e dd7s seems to set up a camel trade with silver getting something extra, maybe a D for a r.

Title: Re: Move 20
Post by Fritzlein on Jan 3rd, 2008, 2:21pm
Chessandgo played 20w Ec5w Ra1n De1n De2w.

We can't push his horse back any more.  We can't pull his dog.  We therefore can't get that kind of compensation for giving up our camel as a hostage.

My first thought is that we either have to get our camel out of there while we still have a chance to avoid giving it up hostage, or we have to push his camel and play for a camel trade.

Title: Re: Move 20

Ok so a few of ideas...

20b mc3n rc3w mb4e mc4n
20b Me3n ed3e rc3e dd7s
20b Me3n ed3e rc3e cc7w

hopefully other people have some ideas as well. i definitely think we will need to play out some lines to decide the best move

Good ideas - but don't forget that Silver cat is now in danger.
I'll try to help a bit later - some heavy blood-spilling looms on the horizon.

The hostage threat is present but I think there's quite a chance to overcome it with swarming... For now I propose:

20b: dd7s hg6e hh6w Rh5n

Title: Re: Move 20
Post by RonWeasley on Jan 4th, 2008, 8:15am
Here's another swarming idea: 20b dd7s dd6s dd5s rg8s

This looks like it gives the silver e some freedom and makes work for the gold E.  That puts the D pull back in play and might let silver win the camel capture race.

After some analysis, pushing his camel looks poor for us.  Chessandgo threatens to get a camel and a rabbit for a camel.

20b Me3n ed3e rc3e dd7s
21w Eb5s rd3w Dd2n Rg1n
21b Me4n ee3n Me5n ee4n
22w Eb4e mb3n rc3x mb4s Ec4w (+=)

Swarming buys us time, but not enough time to get the camel for something less

20b Me3n ed3e rc3e dd7s
21w Eb5s rd3w Dd2n Rg1n
21b dd6s dd5w dc5s rb8s
22w Eb4n mb3n Ha3e Ra2n
22b Me4n ee3n Me5n ee4n
23w Eb5e Ec5w dc4n rc3x Rh1n (+=)

This doesn't mean that swarming is out; it means that if we are going to swarm, we should do so first, and look for an opportunity to push the camel after our swarm has gotten well underway.

What is out in my book (until someone gives a more promising line) is an immediate camel push.

Playing on a bit farther:

22b Me6e Mf6x ee5n ha5n Da4n
23w mb3e mc3x Eb4s Eb3n Eb4n
23b ha6n Da5n ha7e Da6n

The idea being to take the dog hostage after an exchange of camels.

If gold instead plays
21w rd3n Dd2n Eb5s Rg1n
Does this work?
21b Me4n ee3n rd4w xxxx

After looking some more,

20b Me3n ed3e rc3e rb8s
21w Eb5s rd3w Dd2n Rg1n
21b ha5n Da4n ha6e Da5n

And alot of pieces leave the board, but it looks like silver comes out ahead. But it is really complicated and I likely missed something.


Title: Re: Move 20
Post by Fritzlein on Jan 4th, 2008, 8:02pm
A bit of analysis increases my interest in 20b mb3n rc3w mb4e mc4s.  At the most basic level, it threatens to win a cat,.  A more subtle feature of the move is that for chessandgo to retake b3, he can't push our rabbit back into c3.  He would have to push our rabbit away from the c3 trap, and onto a better square for our rabbit.  This raises the possibility that he would defend c3 with his elephant on c4, rather than retaking b3, which leaves our horse free to harrass his dog.  A final subtle point is that if both his horse advance in the west, our rabbit can often take up an ideal spot on a3, allowing our camel the possibility to escape via the b-file and crash the party around f6.

But first the least subtle line.  What if he takes our cat?  It looks like we have more stuff to capture faster, so his only hope is a goal race which we win:

20b mb3n rc3w mb4e mc4s
21w Eb5n Eb6n cc7s cc6x Eb7e
21b mc3n Cc2n Cc3x mc4s mc3s
22w rb3e Ha3e Cf2w Rf1w
22b Dd2s mc2e rc3s dd7n
23w Ra2n Da4e Db4e Ra3n
23b ha5e hb5s Dc4e hb4e
24w Ra4n Ra5n Ra6n Rg1w
24b hc4w ed3w ec3n Hb3e Hc3x
25w Ec7w rc8s rc7s rc6x Eb7e
25b md2n ec4n dd8w hb4s (-+)

It's extremely sharp, and worth further examination, but let's say he can't afford to enter the bloodletting line, and tries to come home with his elephant.

20b mb3n rc3w mb4e mc4s
21w Eb5e Ec5s rb3n Ha3e
21b ha5e Da4n Da5n hb5w
22w rb4w Hb3n Hb4n Hb5n
22b mc3w mb3n mb4n dd7s (=+)

That didn't work so well.  If he comes home with his elephant, his dog is hung out to dry, so maybe he needs to activate his camel?

20b mb3n rc3w mb4e mc4s
21w Eb5e Ec5s Cf2w Me3n
21b ha5e Da4n Da5n hb5w
(but no, the camel gets in trouble for defending: 22w Me4n Me5w Md5w Mc5w 22b ed3n ed4n ed5w mc3e -+)
22w Ha3n Ha4e Hb4n Hb5n
22b rb3w mc3w dd7s ha5s
(now chessandgo's misplaced second rank rabbits prevent him from taking our camel hostage)
23w Me4n Me5w dd6e Md5n
23b mb3n mb4n Hb6n mb5n (-+)

So perhaps the answer for Gold is not in camel activation, but in defending c3 with small pieces to keep the gold elephant free.

20b mb3n rc3w mb4e mc4s
21w rb3n Ha3e Ra2n Cf2w
21b mc3n Cc2n mc4n Cc3n

This last line is unclear, but it might favor us if nothing of ours can be effectively threatened except our advanced rabbit (now no longer framed) while gold has several small pieces and rabbits that are targets for us.

So far I like the move 20b mb3n rc3w mb4e mc4s pretty well for us.

This looks like it would lead to giving up a camel hostage.  21w: Eb5s ha5w Dd2w Me3w.  I expect the a3 horse and a4 dog to go to the c6 area where the horse will dominate. A swarm attack on f6 will follow.  So I don't favor this over 20b: mb3n rc3e mb4w mc4s.
