Title: Move 41
Post by The_Jeh on Oct 5th, 2008, 12:18pm
Chessandgo chooses 41g Ed3e Da3n Da4n Da5n. This is a move we had mentioned.

The move I had in mind at the conclusion of the last thread was 41s ef4w Hg4w dg3n ce6w.

Bomb suggests
 41b Hg4n ef4e rb5e rc8w
threatening to capture his horse in 1 move and delaying the capture of our northwest cat. That 41b seems to lead to us getting his horse for our dog, leaving us with two extra rabbit but with two cats instead of his dog and cat.

My initial thought was

41b Hg4n ef4e rb5e rc8e

- which turned out to be quite similar to the Bomb's proposal. For the last step I assumed we can make a better use of this rabbit in the center, far from the gold dog.

An annoying counter to your "initial thought" is

  42g Rd4wwn Da6n

threatening goal. Isn't it better to send our c8 rabbit west as in Bomb's suggestion to keep him from threatening goal?

Bomb suggests a rather unhuman tactical counter to your 41s:

  42g Ch3w Ee3e dg4nn Hf4e

That 42g  seems to allow gold to escape without further loss of material despite leaving gold's elephant on the trap protected only by a cat.

On a first pass this move looks strong.

I don't want to trade our dog for his horse.  Yes, CRR for D is a material advantage for us, but less than I was hoping for, and with a tense endgame to be played thereafter.  I would not have advocated playing safe last move if I had thought we would have to trade horse for dog.  If we eventually decide we have nothing better than this trade, we'll have to look back and wonder where we went wrong.

Therefore I approve of the step dg3n so that we win the horse without losing our dog.  Note that 42g Ee3e Ef3e xxxx xxxx does not get chessandgo our dog for his horse, because we can answer with 42s Hf4n ee4e xxxx xxxx and get the free horse on 43s.

The down side of the dog retreat is that chessandgo's elephant is less firmly tied to the defense of the f3-trap.  Supposing that he leaves his elephant on e3 in response to our move (as I expect he would), then we can't split our capture of his horse into two moves with 42s Hf4n ee4e xxxx xxxx, because his elephant can advance up the e-file to save his horse, and we don't have the immediate counter of capturing his cat with our dog to create a huge goal threat.  In other words, this move is great for the control game because it is a serious threat to win a free horse, but bad for the racing game, as it may create situations where chessandgo can bail out with his elephant and win a goal race.

I would look first at 42g Ra2n Ra3n Ra4n Da6e.  The goal-in-one threat means that we can't take the horse, which means that we can't get halfway there either.  But using all four steps in the west with 42s rc8w rd5w rb5s rb4w might be adequate to insure that we can take his horse on 43s no matter what he tried to do in the west on 43g.

If instead chessandgo tries 42g Da6e Db6n cc7s Db7e, I am not sure that we can afford a defensive move.  His dog would be eyeing f7, from where it would nullify our threat to his horse.  Therefore I think we would have to take his horse on 42s in exchange for our cat, with the idea of using our elephant to put out the fire in the west on 43s.  We would be ahead by two clear rabbits with, I think, as nice an endgame as we can hope for.

Chessandgo may have other, stronger tries, but at the moment I think The_Jeh's move wins us H for C, resolving the mess of the last many moves into a fluid position where it is (finally) quite clear that we stand better.

That is indeed unhuman. I had completely overlooked that possibility. However, it does not necessarily make me want to reject the move out of hand. For example:

42s ee4s ee3w rb5s rb4s

To lose material near c3 verges on fatal for c&g. Some choices he has are:

43g Hg4w Hf4w Rd4w Ef3w, to which we respond 43s ed3n He4n ed4e rb3s, and we win his horse after all, because responses to save it result in a forced goal for us, if I'm not mistaken. (Or if somehow it doesn't, we could just play dg5w instead of rb3s.)

43g Ef3n Ef4w Rd4w Da6s is easily thwarted by 43s rb3s ed3s Rc2n ed2w, 44g Rg1w Rf1w Re1w Rd1w, 44s Rc1e ec2s rd5e leads to a forced goal.

I'm shaken by my own lack of perception compared to Bomb in this instance, but Bomb could still be misevaluating a move that is actually good if we look a few moves deeper.

How about this one. A possible goal threat.

41b rf7s rf6s rd5e ce6w


Title: Re: Move 41
Post by RonWeasley on Oct 6th, 2008, 10:00am
I'm looking at

41b Hg4n ef4e rb5s ce6w

Gold must leave something to block our r on d5 so the gold E won't be too aggressive to save the H or advance the R on d4.  Gold is trying to create a west side goal threat.  Moving our r to b4 slows this down by creating our own additional goal threat.  Moving our c to d6 makes the f6 trap defensable.   The lack of mobility of the gold E keeps it from taking our dog while we secure the H.  If the gold E gets blockers by threatening a d-H exchange (and move the dog to evade), the E can defend the H but now we have a dog around either c3 or f3 with threatening rabbits and a better goal race.

For some of the other suggestions, I'm not seeing the advantage of the rc8e step.  It doesn't figure into any of my variations.  If anything, rc8w is more useful in the future to defend a west side goal threat.

Title: Re: Move 41
Post by Fritzlein on Oct 6th, 2008, 10:23am
I'm not sure The_Jeh's line refutes warren's (Bomb's) refutation of The_Jeh's move.

42g Ch3w Ee3e dg4n Hf4e
42s ee4s ee3w rb5s rb4s
43g Da6s Da5s Da4s Ef3w

and we get a free rabbit, but it isn't immediately fatal to chessandgo because our attacking rabbit can be pushed back to b4 with a dog in front.  The question is how good for us strategically that position with CRRR for H is.

When using Bomb in the endgame, we should be aware that it overvalues the horse.  Right now, with H for CRR, Bomb thinks that Gold is ahead on material by +1, but if it trades horse for dog the material swings to -2, i.e. a two-rabbit advantage for Silver.  This is not a typo: to Bomb's material evaluator, horse for dog is a three-rabbit swing.

If instead of forcing that trade, we had the option to capture a rabbit for free, Bomb's material evaluation would swing to -1.  We get one point for the rabbit per se, and one extra point for the rabbit surplus in the endgame.

To my mind it's only slightly better to have CRR for D than to have CRRR for H, but in Bomb's material evaluation the former is much better.  Bomb really puts a premium on that horse.  Just so we are aware of the bias.

That said, Bomb did find a strong move I totally overlooked, so I definitely don't want to spurn its help.

Bomb is happy to take the horse for dog trade and declare victory, but after

42s Hg5w eg4n Hf5n Hf6x eg5w
43g Ee3e Ef3n dg3w df3x Ef4w

It seems that we lose another rabbit, the indirect effect of making it vulnerable with rb5s.  But I assume from the commentary

that we shouldn't accept the trade of dog for horse.  So how should the dog evade?  I guess something like

42s dg3s dg2e rh7s rd5e

looks pretty good.  So I am in favor of Ron's move so far.

I think that move is too slow and therefore lets his dog rescue his horse. For example:

41b rf7s rf6s rf5w ce6w

Hi warren,

Camelback's 41s rf7s rf6s rd5e ce6w is my current favorite. It doesn't look good at first because it delays our capture of the horse for a turn, but once we follow through with the horse threat it seems to leave us in a better position than after RW's 41s Hg4n ef4e rb5s ce6w .

Put another way, however C&G responds to Camelback's 41s it seems we'll be in a better position to make threats against his horse and goal than we are now.

Can anyone find a good 42g to counter Camelback's 41s?

Title: Re: Move 41
Post by camelback on Oct 8th, 2008, 8:08am
A good counter for c&g and the following response would be
42w Ee3n Ee4s re5s Rg1w
42b cd6s rc8e rd8s rd7s

I think this could force c&g bring back dog for defense, so position needs further analysis.

Here's the best I could find.  Essentially, we take the horse without giving up the dog.  The won endgame takes a while, like a jdb puzzle.

Here are my responses, at most we will trade a r for H. I think Ron can still find forced goal with his magic wand.

That's a nice tactic to hold his horse on f5 with our elephant on f4. However, the advanced rabbit can actually get in the way of that in some lines. For example:

41s rf7s rf6s rd5e ce6w
42g Rg1w Rf1n Da6e Rh1n
42s Hg4n ef4e rf5s re5s
43g re4n Ee3n rf4n Ee4e
43s dg3s Ch3w rh4s re5s
44g Ef4s Rf2w Re2n Ef3s

But then this line convinced me

41s rf7s rf6s rd5e ce6w
42g Rg1w Rf1n Da6e Rh1n
42s Hg4n ef4e rf5s re5s
43g re4n Ee3n rf4n Ee4e
43s dg3s Ch3w rh4s rc8w
44g rf5n rf6x Ef4n Ef5s re5e
44s dg2s Rh2w eg4e rh3s

with goal to follow

Is the Silver e-rabbit more useful on e5, to unfreeze f5, or on e4 to threaten goal?

41s rf7s rf6s rd5e ce6w
42g Rg1w Rf1n Da6e Rh1n
42s Hg4n ef4e rf5s re5s
43g Ee3e rf4n Ee4n Ra3n
43s Hg5n eg4n rf5w re4s

and we do get the horse for only a rabbit.

Since Ron has covered the possible Gold counter-attack, and the Gold defense looks mostly hopeless, I guess I'm finally on board for camelback's move in the continuing voice vote.  I'm ready to move if everyone else is too.

As if I needed another reminder that my endgame instincts are poor, I originally thought advancing the f7-rabbit to f5 would not be threatening enough, and would allow chessandgo time to consolidate, when in fact it ties him down and makes our advantage clearer. I hope this kind of analysis eventually helps me repair the big hole in my game.

Camelback's move is sagacious. Just casually playing out follow-up moves, everything just seems to naturally and swiftly flow in our favor. I'm behind this move if for no other reason than that I want to see Chessandgo's response.

I'm fine with camelback's move as well.

I concur. I'd like to see Camelback's move played.

TheMob has spoken.  At least enough of it.  I shall play:

I think anybody who plays as well as chessandgo or Fritzlein is not only a wizard, but uses dark magic and illegal spells.  Slytherins both.

I think maybe Adanac is a Ravenclaw.

Looks to me like this would transpose into one of the other variations we've considered, but I'm fully expecting chessandgo to pull some potion out, confuse our rabbits and get the advantage again.

If I recall correctly your namesake once played a high-stakes game of chess in a dungeon that Dumbledore called "the best game of chess Hogwarts has ever seen". Your conclusion that F and C&G are necessarily Slytherins is dubious.

Namesake?  What namesake?
