Don't know that the analysis has the correct answers. But these are positions of interest given a relatively deep look:

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Something strange with latest ASM fish 2016-08-30. on arena 3.5.1
[d]3R4/1p4k1/1n2R3/p1p4B/P1P5/1q6/5PP1/6K1 w - - 0 1
Just analysed first position, in first analysis, SF says 1.g3 and mate in M19 and didnt search another alternative move. Second time after restarting arena, Rdd6 and M 20, and didnt search alternative as well. :(

It's a hard problem to get the minimal mate.
Move g4 is mate in 16.
