Move 38

I have to take family to Hogwarts and will be gone until Wednesday.  My guess is that we won't want to move before then unless gold captures the horse as in our main line.  In that case, our response is ready and one of the people who know the spell for the TheMob account can just make that move if TheMob is in agreement.

1. Slay the dog ( 2 steps ) + return to f4 ( third step ) + fourth step(?)
 
2. How about 38s ef4w ee4e Re3n rd5e - Jean's horse has a knife against his throat...

38s Df5n Df6x ef4n ef5s dc5s
 
Just the first thing that stood out to me when looking at the position.

38s Df5n Df6x ef4n ef5s rg4e came to my mind first - (threatening ef4e eg4w Hg3n dg2n later)
 
BUT
 
that plan seems to be to slow so:
 
38s Df5n Df6x ef4n ef5s dc5n is the move that buying us time and I currently support this move.
 
 
 
 
Our 38s seems to be all about fourth step, so currently we have:
 
rg4e - maybe promising but there will be some sharp STRATEGICAL lines (turning into tactical ones) that has to be explored first (and currently I think it is not the good choice)
 
rd5e - I don´t really understand meaning of this fourth step - any detailed explanation why is it sharper knife against horse than rg4e? Soter?
 
dc5n - seems to be the only one logical choice right now.

This fourth step wasn't for the dog-capturing move, but for Soter's alternate tactical shot 38s ef4w ee4e Re3n rd5e. The rd5e is necessary to prevent the dog from slipping away.
 
And I'm sure I'm missing something, but why move dc5s when just last turn we made a point of moving dc4n? Our horse isn't salvageable, is it? Wouldn't we just be throwing away a piece or a tempo (unless it is vital to keep the E in the corner one more turn)? I like the rg4e idea better, because it threatens 39s ef4e eg4w Hg3n dg2n, which would be a great position.
 
[Edit:] Do you guys mean dc5n? That would be logical, putting the dog out of capture range after our horse is captured.

The strongest 39g I see after that 38s is 39g Rg1w Rf1n Ch3n Da3n, which seems to force us to lose a horse for a dog (like the other 38s proposal).

Like The_Jeh, my fourth step is dc5n, conceding the horse and preparing for 39s rg4e ef4e eg4w Hg3n, or something better.  The point is that silver has full initiative on 39s.

That's also my feeling at the moment, but I haven't looked at it for long.

Since we're in the "first impression" stage, let me throw in my support for 38s Df5n Df6x ef4n ef5s rg4e.  The thought is not to retreat our dc5n unless necessary.  If his elephant comes across instead of up, we have saved a step.

Ahhh, sorry, my mistake, now it is perfectly clear to me. Thanks.

Yes, indeed - I meant dc5n - thanks for notice.

After looking a bit more at 38s Df5n Df6x ef4n ef5s rg4e I still like it.  I don't think chessandgo's elephant can afford to come sideways, because that gives up his horse as a hostage.  He has to capture our horse through to c4 to force us to spend a tempo to save our dog.  But then our elephants are on opposite wings in a race.
 
I haven't worked through a lot of lines, but generally speaking we want to race because chessandgo will have the deputy (second-strongest piece unopposed, i.e. his horse).  If our elephants get entangled with each other, then his deputy increases in power.  But if our elephants are apart, racing, then our numerical superiority should weigh more heavily than his strength.  I like the line for this general reason, not because I see some great tactics for us.

38s Df5n Df6x ef4n ef5s rg4e
.    39g Eb3e hb2n Ec3e hb3e hc3x
.    .    39s ef4e eg4w Hg3n dg2n -+
.    39g Eb3e hb2n Ec3n hb3e hc3x
.    .    39s dc5n ef4e Hg3w eg4s
.    .    .    40g Ec4n rb5s Ec5w Da3e
.    .    .    .    40s dg2w Hf3n eg3w dc6w -+
.    .    .    40g Ec4n rb5s Ec5w Hf3s
.    .    .    .    40s dg2e eg3s Hf2n eg2w =+

 
I look at other moves as time permits, but since this move seems to retain a palpable advantage, things can only get better from there.

Seems that the dc4n and rg4e moves transpose into each other in our main lines.  Given that, I have no particular preference, although I see Fritzlein's point about a more forward dog perhaps being more forcing.
 
With comments dropping off, should we consider a fast response and a gain of reserve?  If you think so, give us a voice vote.
