I like the extra goal threats. That's currently my favorite 41b.

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
 
Quote:
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.

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.

Really, this would force us to defend. It's better to have initiative on our side.  
 
I like the look of the Camelback's proposal. Any possible continuation?

I think that move is too slow and therefore lets his dog rescue his horse. For example:
 
41b rf7s rf6s rf5w ce6w
42w Da6n Da7e cc7e Db7e
42b ef4s Hg4w Hf4n ef3n
43w cd7n Dc7e Dd7e De7s
 
Update: oops, my above continuation is not for the 41b camelback posted. I'll have to investigate your 41b more to have an opinion.

Hi warren,
 
I was planning for goal threat by advancing rabbits, since there is very little defense. I have the following lines.
 
41b rf7s rf6s rd5e ce6w
42w Rh1n rh4n Ch3n Hg4n
42b ef4e rf5s re5s rh7s
43w re4n Ee3n rf4n Ee4e
43b re5s cd6e ce6s re4s
44w Ef4w re3w Ee4s Rg1w
44b rf5s rf4s rf3s ce5s

I ran opfor after
 
41s Hg4n ef4e rb5e rc8w
    42g Rg1w Ee3n Ee4e Rh1w
    .    42s rd5e re5s ce6s re4s
 
to see if it could find a refutation
 
depth 15
time 22134
nodes 2333603212
qnodes 124024877
losing_moves 3246
score -617
pv Rg1n Rh1n Da6e Db6s b eg5w Hh5w Rg2w dg3s w Db5n Db6n cc7s Db7e
 
So it just keeps looking worse for c&g in that line the deeper opfor goes.

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?

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 a full continuation for my suggested move:
 
41s Hg4n ef4e rb5s ce6w
42g Rg1w Da6e Db6s Rh1n
42s dg3s Hg5n eg4n rc8w
43g Rd4e Re4e Rf4n Ee3n
43s Hg6e eg5n cd6e rb8s
44g Ee4n ce6n Ee5n Db5e
44s ce7w cd7s rd5s rd4e
45g Dc5e Dd5e De5w re4n
45s dg2n Rh2w rb4s rb3s
46g Dd5s Dd4s Dd3e Rf1e
46s cc7s cc6s rb7s cc5w
47g cd6n Ee6w Ed6s Ed5w
47s eg6w ef6e Rf5n Rf6x cd7w
48g cb5s Ec5w Rg2e
48s eg6w Hh6w ef6s Hg6w Hf6x
49g cb4s Eb5s cb3e cc3x Eb4s
49s ef5s ef4s ef3s De3e Df3x
50g Eb3e rb2n Ec3e rb3e rc3x
50s dg3n Ch3w Cg3w Cf3x dg4s
51g Rc2n Rc3n Rc4e Rb1n
51s rh4s dg3s re5s re4s
52g Rd4n Rd5e Re5n Re6n
52s cc7e ef2n re3s ef3x re2s
 
Here's one of the camelback variations:
 
41s rf7s rf6s rd5e ce6w
42g Ee3n Ee4s re5s Rg1w
42s rf5w Hg4n ef4e re4e
43g Ee3n rf4n Ee4e Rf1n
43s dg3s Ch3w rh4s rc8w
44g rf5n rf6x Ef4n Hg5e Hh5s
44s Cg3w eg4s rh3s eg3e
45g Rd4e Re4e Rf4e Rg4n
45s Rf2w Cf3x dg2w rh2w rg2s
 
Here's another:
 
41s rf7s rf6s rd5e ce6w
42g Rh1n rh4n Ch3n Hg4n
42s ef4e rf5s rf4s rf3s
43g Ee3s rf2e Ee2e Da6e
43s cd6s Rd4w cd5s re5s
44g Rc2e Rb1n Rb2e
44s cd4s Rd2s cd3s re4s
45g Rc4e Rd4e Re4n Re5n
45s re3s re2s
 
So I think both moves win.  Camelback's appears to win quicker.  While these aren't likely the best variations, they show a lot of the relevant themes.

Wow you have it down for goal in five or six moves?  I didn't know we were winning by that much...  I can't wait to analyze our crushing attack.

Based on my posted analysis, I also support
 
41s f7s rf6s rd5e ce6w
 
But please be careful.  Just because I gave out lines that go to goal, doesn't mean the Slytherins are going to cooperate.
