[Ponti]

Interesting program.

Here´s my own analysis:

1.e4 {better is 1.c4 or 1.d4 or 1.Nf3 if you want to win a WCh.match) e5 {better is 1...c5 for the same reason...} ...

Cerebellum prefers the Italian game, WOW !

Just scratching the surface, Brainfish 19Nov2016 (2 threads on i7-2600K) at 2 minutes/node (except at root node which is at 4 minutes) multipv is set to 3 to generate the best 3 moves in every node, it likes RL. There must be a lot going on in cerebellum .

[glennsamuel32]

Is there a way to have the engine analyse and print only the best final move into the given pgn ?

For example...

test.pgn --- final move is 25...Re8 (black)

output.pgn --- final move is 26.Bb5 (white) which the engine analysed and printed.

Thanks !!

What is your purpose in doing this, adding only the final move of the anotator? I don't like adding options that are not generally useful. Can you give an example in pgn format?

I completely understand if you feel it's unimportant.

For use on the Infinity Chess server, to exit the opening book with a strong move.

You can do this with Engine Match under a Fritz GUI by setting Game Length to 1.

Works perfectly...thanks a lot !!
Never knew we could have a 1-ply engine match

I think it is possible.
