I'm persuaded that the Mb4 step is not good in conjunction with gh5 and h3.
The horse pull still seems unclear. After 8g Mb4:H 8s Ec4 h5 De5, aside from the g5 rabbit, we still have a lot of positional factors in our favor.
I don't know what to expect from silver after 8g gh5 h3 gh2. Perhaps 8s Mg5:H H:hg3?

What happened to my suggestion of 8g Rg5e Rh2n Ra4n Dd3n ?
An alternative response to
8g: Rg5e Rh2n Ra4n Mb3n
8s: ee4e ed4e ec4e Mb4n
is the run away defence
9g: Mb5e Mc5e Md5s Md4s
This would cost both sides the same number of steps to return the M and e to the original positions, so on second thoughts this looks like a viable move.

And what about silver trading m for DCR, would you prefere stronger or bigger army?

We retain a big positional advantage, so I much prefer gold.
10s ec2w Dd2w Dc2n Dc3x eb2e
11g Hf3w mg3w mf3x Eg4s Eg3n
Gold is clearly winning.

I am not afraid of tactical answers, but rh5 ewwx let silver in very fine position (maybe x=dd6s).

Is that true Hippo? I only see one. 3g moved four pieces, but the d file dog step depended on the camel step. 8g was four independent steps, but I think a good argument can be made that this is one of the exceptions where a Haizhi move is still good (after all, he didn't find that good players NEVER played these moves).
Conversely, sharpvector has also been playing Haizhi pruned moves. 3s is an almost-hit, like our 3g. 4s and 5s were both four independent steps. So on this metric, perhaps we are playing "better" than Sharp and lightvector  .
