This bonus game give me some interest!

rnbqkbnr/pppppppp/8/8/8/PPPPPPPP/RNBQKBNR/8 w kq - 0 1


Some engines played d4, some e4, but i think really most precise and killing move is Ra1(!).

rnbqkbnr/pppppppp/8/8/8/PPPPPPPP/1NBQKBNR/R7 b kq - 1 1

26 possible moves, all are good  :, evals 1.42(Kf1) ... 0.54(Nf4,e5,Ng2)
23rd still has eval 0.96   (depth 40(4) , multipv , CFish 2018/08/18 )

This could be a good starting position for TCEC-superfinal
oe correspondence chess tournaments , to reduce drawrates

oops, I had entered the position into droidfish and forgot to set
the castling flags. With black being able to castle, the evals
are only ~0.80 , I restarted it with asmfish 2018/09/24 contempt=0

multipv=26 asmfish evals at depths 1,...46 (4 cores , 512MB hash)

Addendum:
Still today's best engines (also Stockfish) not so well understands own pawn wall (e.g. a3-b3-c3-d3-e3-f3-g3-h3).

Actually this position again is a good test position for engines! -- couple of good moves (Kg1, Re1, e5, h4).
