I can add that I now test the easy positions automatically and it seems that
part of them are not so easy.

I expected based on Antony that movei on A1000 will solve all of them in a short
time but it does not do it.

I implemented function to analyze epd and not leave a position before mate
unless very long time was used and I test it with this function.

The fact that there are a lot of easy problems does not mean that all of them
are easy and solving all the positions on p233 in less than a minute(not one of
them) is clearly a good result.

Movei was not designed for finding mates and I disabled many extensions when the
side to move has a big advantage but I do not think that by only changing
parameters I can get all the positions in less than a minute.
