Can you put crazystone back on 19x19 so I can see if it is just a fluke

I added locality to the light playouts - play near last or second to last
move, and some code to handle long ladders in playouts. I don’t think this
is anything unusual.
I think you have a problem with ladders. Crazy Stone played three games,
and all started by a huge ladder-like tactical blunder by Many Faces.
Maybe you should try keeping the locality change, and dropping ladders
in the playout.
Crazy Stone does almost nothing special for ladders. The only use of
ladder knowledge is as a pattern feature, as explained in my Amsterdam
paper. It is not used in the playouts, only for progressive widening. I
never managed to obtain any significant strength improvement by
incorporating ladder knowledge in the playouts.
I can't leave Crazy Stone on CGOS longer, sorry.
