I quite like this move, too. {...} I rank it second only due to personal preference to avoid sharp lines. I hate to race when I am not sure I will win the race, and moving our elephant out of the center commits us to racing if that's what chessandgo decides to do. |

Here's one line that might follow if he decided to race without defending his camel:
3b hb7s ed4s ra7e rh7w
4w Ed6n me7s Ed7e Hb3n
4b ed3e Md2n Md3n ee3w
5w me6s Ee7s Hb4e Md4e
5b ed3n ed4n me5e mf5n
That would leave us roughly even by my reckoning (since he has the next turn and can also retreat his forces if he wants).

This can't be correct unless the elephant-horse attack is sound in general. If the elephant-horse attack were generally sound, then the opening would be all about who could get in the first shot. This would be a great way for us to be the attacker rather than defender. If you simply must play around the opponent's traps rather than around your own, then by all means take the fight to the other side. However, even if some elephant-horse attacks are sound, I don't believe this one is. I think chessandgo would get the advantage simply by bringing back his elephant to f4, taking our horse hostage. |

I don't see any clear way he can take our horse hostage with his camel (which is the main risk to EH in my view). We could then send our dog up behind our horse, and play like chessandgo! The main upside is targetting the h2 rabbit.

Well, this may be too late with voting already underway. Do we really need 2.5 days of voting? My inclination would be to cut the voting down to only 1.5 days, and if we have another spare day, use it for extra discussion instead.
In any event, Katie and I have moved out of our apartment and into our house. It suddenly occurs to me that there is no deadline on unpacking. I can live nicely in the middle of piles of boxes, thank you, as long as the computer is set up so I can get my daily Arimaa fix.

This move keeps things safe for the immediate future, but it seems to leave chessandgo with a path to improve his position at no risk. A move like 4w Ed6e md7s Db1n Cf2e develops gold's position without committing to anything yet. Although it took only two steps for him to threaten our camel, we would need more than two steps on defense, and would have trouble keeping our camel in position to scare off gold horses from both wings. Indeed, if our camel became restricted to the west, Gold is immediately threatening an EH attack on f6.
Yes, we could taunt chessandgo a bit by moving our camel next to his elephant in a way that is safe for us, but unless it provoked him into a poor move, it would just let him quietly gain tempo and/or position.

But don't forget the other threat to the exposed horse, namely a frame. After your move, 5w Cc2n Md3s Ef4w hg4w threatens a horse frame before our dog is ready to come to our horse's rescue. We would have to bring up our camel to unfreeze our horse, and leave our camel on an awkward square in the process. I think chessandgo could get plenty of play before we got our forces organized.
In general, I think the soundness of an EH attack depends not merely on the position of the enemy camel, but also on the position of the friendly camel and supporting dog. If we want to launch an EH attack, then let's get our dog in the right spot first, so our camel doesn't have to end up in the wrong spot.

12 of 15 voted. Tucked rabbits wins! This was unexpected to me from the discussion as defensive west and M half pull seemed to have the most vocal backers. But this is mob rule!
For the next moves I am going to try to lay out a schedule early for discussion and voting so that we make our move in less than 7 days. It seems like mobsters need a 2 day window to vote, based on the last two moves. We will continually refine this.

Very interesting. Like Ron, I'm surprised the M pull didn't win the vote. I thought folks would go for the most tangible objective rather than dinking around like I wanted to with my first choice.
Maybe folks picked 99of9's move just because they were tired of me trying to dominate the conversation.  Or maybe it was a case of a compromise candidate coming out ahead of two extremes.
I think we may have already equalized, despite having the Silver pieces. Will chessandgo take the offered lone-elephant race, or will he launch a premature elephant-horse attack? Either way, I think we are fine.
For the record:
. . . . . . . . 1. 2. 3. 4. 5. 6. 7. 8. 9.
1. hb7s ed4s ra7e rh7w (tucked rabbits) - 7 7 10 10 9 10 11 11
2. hb7s cc7w dd8s dd7w (west defensive) 5 - 8 10 10 9 9 11 12
3. hb7s ed4s ed3e Md2n (M half pull) . 5 3 - 9 9 9 9 11 11
4. hb7s ed4n dd8s ce8w (E cap) . . 2 2 3 - 8 8 9 11 11
5. hb7s ed4s dd8s ce8w (e d up) . . 2 2 3 3 - 6 6 11 11
6. hb7s dd8s hg6s hg5s (immediate eh) 3 3 3 4 5 - 6 10 10
7. hb7s me7w ce8s df7s (catdog up) . 2 3 3 3 4 3 - 7 9
8. hb7s me7s dd8s dd7e (m up) . . 1 1 1 0 0 0 3 - 7
9. dd8s rc8e me7s df7w (dogs behind m) 1 0 1 0 0 0 0 1 -
This was my ballot, except I reversed 1 & 2 and 6 & 7. I wonder whether, a year from now, I will be more sold on the E-H attack.

Strange hearing you say that considering this. My own personal research also supports the extremely tentative hypothesis that if anyone is supposed to have an advantage, Silver currently has the better claim.

That's because Fritzlein is a firm believer in his own intuition rather than the contrary statistical evidence that he himself has presented.

Heheh. You have me pegged, Janzert. In the past I leaned towards explaining the data as a pure statistical fluke. Today my favorite theory is that we are so far from a correct understanding of Arimaa theory that Gold typically uses the advantage of the first move to hurt himself.
