Chessandgo's move is exactly predicted. He has chosen 23w Mg5w Hg3n Hg4n Hg5n.

Title: Re: Move 23
Post by UruramTururam on Feb 5th, 2008, 3:27pm
Yes, he had that answer prepared...

Now what?

Perhaps:
23b: ed3e ec3w Ce2n dd7s


Title: Re: Move 23
Post by RonWeasley on Feb 5th, 2008, 7:24pm
Fritzlein's continuation 23b ha5s ha4e df7s rf8s looks very playable.  Notice the false protection threat against the C on c2.  This will probably force play along the lines in Fritzlein's tree.  I would expect the bottom branches to be played.  It gets very sharp, so look closely.  I still haven't decided if it's good, but I don't think it's bad.

I don't think this sets up enough of a threat (he has a 1 step defence of the cat).

At the same time, it doesn't prepare us to escape being tied down defending the c3 trap.

If we aren't active enough, he will soon take over our f6 trap.

How about:
24w Mf5n he6s Mf6w Rf1n

There are alot of tactics, but I think gold at least gets his rabbit back.

. . . . 24w Mf5n he6s Mf6w Rf1n
. . . . . . . . 24b ed3e ee3n he5e mc3e

Now we have a threat on the cat, we are using his dog to protect our camel against his elephant, and we have are almost in position to pounce on his MH attack with our elephant.  Getting a rabbit from us will be the least of his concerns!

. . . . 25w hc4s Ec5s rb3n Ha3e framing our horse to our camel with the E nearby.  This appears to lead to a MH for mhr exchange that I don't like.

Or else gold takes our cat in a sharp continuation that looks only even at best.

Instead, how about 24b De4e ee3n mc3e Cc2n Cc3x?  This sets up a very sharp exchange race on c3 and f6 where we may be able to maintain our advantage.  Not sure.
[Edit] Looking more at this 24b, gold can just take the dog on f7, put a rabbit on c2, and remain up by a dog.  So I can't find a good 24b for us.

24b ed3e Dd2n Cc2e mc3s

The horse frame is not so deadly now, but alot of pieces could leave the board quickly. With the camel behind the trap, a capturing race should (?) favour us due to the advanced rabbit.

Title: Re: Move 23
Post by Soter on Feb 7th, 2008, 9:44am
Some rather raw ideas:


1.Hypothetical sharp line ( assuming that Gold goes with 24w Mf5n he6s Mf6w Rf1n after 23b ha5s ha4e Dc4e hb4e ):

24b ed3e ee3n mc3e he5e
25w Me6w Ec5n Ec6s cc7s cc6x
25b md3w hc4w mc3e Cc2n Cc3x
26w dd7w Md6n dc7s dc6x Md7w
26b md3e Dd2n Dd3w Dc3x me3w

Now C&G must switch to goal defense ( though the whole thing is rather complicated, with dozens dangerous deviations).

2. What if:

23b ha5s ha4e Dc4e hb4e
24w Mf5n he6w Mf6w Rf1n

In this case our horse cannot reach f5 - only our elephant can do it. he6w (instead of he6s) will hurt Silver much more imho :-/.

3. Now a different kettle of fish: 24w Rh1 Rh2n Rh3n Rh4n ( or some similar move involning flank rabbit offensive ) - do you consider this answer viable for Gold and worth preparing for?

4. My proposals ( not examined very deeply yet, but maybe we can grow sth out of it )

23b ed3e ee3n ee4e mc3e
23b ed3n ed4e Dc4e mc3e

Chessandgo doesn't need to enter a wild, sharp line.  He can use two steps to push our horse back to b4 with his elephant.  In fact, those are the same two steps he needed to defend c3 in my line, so we are just two steps short.  Maybe my last two steps aren't the best, but it seems a waste to use them pushing the dog.

Well, I returned from vacation to find the pressure was on at work (poor Omar) and therefore decided to turn in early and get a good night's sleep to better survive the week.  As I was drifting off, however, I thought of the insanely sharp move 23b ed3e ee3n ee4e mc3e, and all hope of sleep vanished.  That move would give us a direct threat to capture chessandgo's camel in f3, a threat to frame his horse in f6, and strategic threats such as occupying b3 with our horse or swinging our camel through f3 up to g5.  Of course any line as wild as this hinges on tactics rather than strategy, but I couldn't find a refutation in my head in bed, so here I am analyzing with the game client.

At the moment we have an extra rabbit, but chessandgo has counterplay.  These lines seems to end with us having an extra rabbit for no counterplay, or some other solid positional advantage that isn't compensated.  In other words it seems to improve our position.

Given the super-sharp tactics, I once again consulted Bomb, and once again got garbage suggestions.  It is becoming amply clear that Bomb sucks at tactics at postal speeds.  (If Bomb can't help in a position like this, when will it be able to help?)  We need some human eyes to look over these lines.  At the moment this is my new favorite move, but one oversight in my analysis could totally wreck it.

Sorry I didn't see this earlier, but given that I have seen it, I think we need to delay the vote and dip into reserve a bit to verify it.  If this move works, it should be well worth spending a few days of reserve.

I agree with the delay.  I haven't found a clear refutation so far.

Title: Re: Move 23
Post by RonWeasley on Feb 12th, 2008, 7:12am
The best reply I could find was the last one on the tree.  That line looks rather forced.  I don't see much opportunity for counterplay and it ends with silver to move with gold weak on the west side.  We would be looking for an e-d attack.

So I like this new move.

Hey to all! I'm glad that my proposal met with approval  :).

( EDIT:Whoops!  :o I was mistaken - Fritz, you beat me to it; you mentioned this move in "move 22 thread" ).

It looks like i'm going to have a decent amount of free time till end of February - so two more eyes to scan the board. Now I'll try to check some lines, especially from Karl's tree and post something later.

24w Rf1n Dc4s Ec5e Ed5s

Framing the horse. If silver also frames a horse, gold retreats the camel, likely ending up with a camel hostage after the horse exchange.

So lets say silver tries to get the camel out of danger,

25b md3e hc3x me3e mf3e Rf2n Rf3x

For this to turn out reasonable, silver needs to at least capture the horse. Can silver force a horse capture or not?

Sorry, Soter, I didn't read your post carefully enough.  I thought you were giving moves in a deeper line, not in the present position.  And I can't claim to have thought of the move first in the move 22 thread, because that was a very different position.  In future I will try not to ignore any of your proposals, especially when your suggestions are better than mine!  ::)

Continuation of jdb's line:


25b ef4e eg4n hg6w eg5n                     ( gold H framed )
26w Ec4e Ed4w md3n hc3x                    ( silver H dead )

27w Ec4n md4w mc4s mc3x Ec5s           ( silver M dead )
27b Mg5w eg4n Mf5n  Mf6x eg5w          ( gold M dead )


...and 28w sees silver rabbit dead as well, nullifying our so hard-won material advantage. Fritz's "send dog to c4" idea ( you mean 24b dd7s dd6w dc6s dc5s, right? )holds water IMO. The number of possible deviations, however, makes my head spin. Most importantly, is it possible that Gold may withdraw his M, sacrificing his H and still find some way to finish off our pieces near c3 (?!) Maybe I am overreacting, but we all know Jean's ingenuity.

What follows, for example, after

23b ed3e ee3n ee4e mc3e
24w Hg6s Mf5w Me5w Md5s

This puts the pressure on c3, as it makes it more difficult for our ha5 to come to the rescue of our camel. It also looks like we cannot go after the lone horse on g5 without losing our camel via 25w Dc4w Md4w Ec5e Ed5s or 25w Ec5e Dc4n Md4w Ed5s, but I'm probably missing something.

John,
Some responses to your 24w Hg6s Mf5w Me5w Md5s came to my mind ( not that they satisfy me  :-/ ):

1. 24b ef4n ef5s Hg5w xxxx

2. 24b ef4n ef5w Hg5w xxxx ( step #4 : dd7s/ha5s/something else? )

3. 24b he6e hf6e ef4w xxxx ( Gold H won't mess up with our rabbits that way )

All of them do not provide sufficient protection for our M though. If you aren't missing anything then my proposed move 23 is probably a dud. I'm going to have a second look tomorrow as I'm a bit sleepy now.

P.S. What if your 24w features gold M going north instead of south (Md5n)?

What about moving our camel to threaten his horse?

Title: Re: Move 23
Post by The_Jeh on Feb 12th, 2008, 4:22pm
I think he will probably then push our camel onto f6, creating a strong threat against our b3 rabbit.

On the other hand, a good reply for us might be 25b ef4w Md4n ee4w ha5s, so maybe this move is all right.  But 26w Ef5w Md5w Ee5w Ed5n re-complicates things a bit, as does 26w Ef5w mf6s Md5n Rf1n so I would like to know your opinions on continuation from here, or whether another 25w, 25b, or 26w is better. When I go forward in time, everything seems to turn out good for us. I have not examined variations like 25w Ec5e Ed5e he6e/he6w Ee5n, which could be viable.

Soter, I had considered your Md5n variation of 24w in the past, but stopped looking at it for some reason I have forgotten. I'll have to look at it again. I think it was that it results in gold losing control of his camel for inadequate compensation.

26w Hg6s Mf5w Ec4n Ec5e    (Gold could have something better here...)
26b mg3n Hg5n mg4n ef4n

Silver ends up down a dog for a rabbit, but has a horse held hostage (or framed) by the camel. Now if I only knew who was winning...

This is indeed very unclear.  We are not down material: in fact we have two rabbits for our dog, which I rate as material equality.  I don't think that Gold has time to capture our b4 rabbit due to the framed or hostage horse.  However it is not clear to me who has the positional advantage.  A couple of lines:

I can't think of this line as a refutation of Soter's move, because we come out ahead in many lines, but it doesn't clearly give us an advantage like I first thought, and in many lines I'm still note sure who is winning at the end.

I've spent too long analyzing at this depth since the game probably won't go in this direction.  I'll try now for some analysis closer to the root.

On the other hand, a good reply for us might be 25b ef4w Md4n ee4w ha5s, so maybe this move is all right.  But 26w Ef5w Md5w Ee5w Ed5n re-complicates things a bit, as does 26w Ef5w mf6s Md5n Rf1n so I would like to know your opinions on continuation from here, or whether another 25w, 25b, or 26w is better.

Nice analysis.  It's hard to ever get closure on these wild positions, but going forward just one more move in your lines it seems we stand somewhat better, i.e. your 24w is not a refutation of Soter's move.

Well, rats.  It looks like I can't get around JDB's refutation of Soter's move by defending with a dog, because the dog isn't strong enough:

But we can't defend with the horse instead of the dog on 24b, because losing the horse is too costly.  So suddenly I'm leaning against Soter's move 23b ed3e ee3n ee4e mc3e because 24w Dc4s Ec5e Ed5s Rf1n appears to refute it.  Let me look again at my original 23b from last week and other proposals.

How would you continue after 24w hc4w Ec5s Ce2n Rf1n?  I'm not sure what would be a good plan from that position that we shouldn't start doing on 23b instead...

If we use Soter's move, could a possible 24b be 24b ha5s ha4e Mf5n ef4n? This is the only way I see of defending c3 without putting a piece on c4. Chessandgo won't trade, because we'll have his horse, too. Or is this easily refuted, too?

I hadn't considered the first possiblity, because I assumed that the Gold camel would prefer to stay out to the center and out of trouble, but I find it difficult to refute.  After

23b ha5s ha4e df7s rf8s
24w Dc4e Ec5s Mf5w df6s
24b ed3e ee3n ee4e mc3e

we seem to be holding our own, but it is unclear, and I change my mind who is winning each time I play it out.

The second possibility is also very interesting.  A couple of weeks ago I had played some lines where chessandgo lets our rabbit to a3 and our camel out to b3, and I concluded that in general our camel is very hard to take hostage from that setup, and in fact we have a good chance for the camel to escape up the b-file pushing something in front of it to eventually threaten in c6.

However, if Gold combines rabbit pull with rabbit advances, it makes it harder for our camel to get out, and the advanced horse/rabbit/dog for Gold are starting to get populous enough to defend each other.  I like a move on the lines of

23b ha5s ha4e df7s rf8s
24w Ha3n rb3w Rb2n Rb1n
24b hb4n Rb3n mc3w ed3n

But this is very tricky because our camel can sometimes get blockaded on b3.  I haven't played many positions like this, so I have trouble evaluating it.  I'll have to chalk it up as another "unclear" line after my suggested 23b.  Is every line from this position unclear?  I have to give OpFor some credit, though, as its lines seem more to the point than Bomb's.

That's trivial to refute.  Or, well, it took me four tries to "refute" it and then the best I could do for Gold was equality.  So I guess you have rehabilitated Soter's move in my mind up to equality or a tiny advantage for us, since there was only the one critical line beating it.

But wait, that last line isn't equality: we can save our rabbit and remain a rabbit ahead.  So maybe Soter's line is actually still to our advantage?  I'm changing my mind so many times I'm getting dizzy!

My tree is likely off a little (or a lot), but what is certain is that this 23b is very complex (which of itself favors us). I think though, that there is no clear way to refute it, and well into our reserve, it is time to think about voting. If this move does get played, I will be quite curious to see c&g's reaction.

Golly, with a tree like that, I don't think I could bear to vote for anything else and lose all that analysis!  I'm ready to vote for Soter's move any time, unless someone re-refutes it...  :P

Wow, theJeh, this is the largest tree in the Mob history . My jaw will hit the floor if chessandgo escapes from this one .

By a unanimous 10-0 decision: 23b ed3e ee3n ee4e mc3e .   I keep thinking I'm going to move wrong one of these times.

And chessandgo comments that we seem to be moving in a Bomb-like way.  He said that after we took his rabbit.

Is it the first unanimous vote in mob history?

Let's hope it won't lead us astray.

We play like Bomb?  What an insult!  Bomb is at best mediocre at postal speeds.  I vote that we tell chessandgo he plays a lot like Gnobot.   ;D

The cool thing with my book chapter on this Mob game is that whenever I can't find a refutation, I just have to look into the Mob's forum to find it. The bad thing, obviously, is that everyone who reads my chapter is going to say: "your analysis is so superficial c&g, half of your proposal have been refuted way before you even considered them!" :)
