Zappa is a very strong engine but it is in trouble here in this position.

Nice......

Zippy-dee-doo-daa

>but you can't test engines on illegal position with direct checks,hitting kings
>and position having 32 or 22 knights

Yes you can.

>If you promote the pawn to bishop,can you get the knight later?

Yes

>are there no possibility for black to draw?with one knight vs 2 white bishop?

b1B loses for white. It is not even close to a draw.

>right,very interesting position,I wonder where you got those position?
>is this position there in a test suite?

Fairies (no joke) and yes but the suite is private for obvious reasons. These
are only 3 positions in this thread out of thousands.
