New release Pedone 1.6

[Guenther]

In the second log Pedone was playing with Black. Maybe now the problem gets from something related to timing in my GUI (but the GUI itself doen's hangs).

I know it should play for Black in your second log, but it calculated a White move Nc3? after 1.Nf3 from Sabrina...

I know it should play for Black in your second log, but it calculated a White move Nc3? after 1.Nf3 from Sabrina...

I haven't noticed that! In effect, it seems that Pedone is playing white:

Code: Select all

B	--->	position startpos moves g1f3 
B	--->	go wtime 14811 btime 15000 winc 200 binc 200
B	<---	readyok
B	<---	info multipv 1 depth 1 time 0 nodes 27 nps 27000 tbhits 0 score cp 151 pv b1c3 

It appears as "position" command is ok but maybe I'm missing some other command to send from the GUI?

Here is a game with a 5men endgame which was not optimal solved by Pedone:
