Check is only one case of extended moves. All extended moves SmarThink searches
at full depth (+extension).

Something like that. I think it will be publicied in future.

I'm working on it. Now, the one annoying thing that fixed is a bug with mate
with two queens (or queen+rook). All other improvements are still only
eval/search. UCI and time bugfix will be done in next version also.
