Re: a position beyond the scope of most top engines....

After 1 hour on my machine (reaching depth 29), Critter 1.6 with 4 Gb of hash gives an eval of 0.00.

Re: At a glance you may think this is a draw. White wins!

The thing is I cannot use the "Set Value" button because the dropdown menu for setting values like Wins, Loses, etc is blank and nothing can be selected. Click on the "triangle" of the dropdown menu: then it will show the values to choose from. That's what I did, Arpad, the menu does drop down but ...

Re: At a glance you may think this is a draw. White wins!

You must use a special version of FinalGen: http://www.mtu-media.com/finalgen/oldversions/FGen_1.3HWSP_Setup.zip Sorry, Arpad, but after having installed the version your link downloads instead of 1.3 I already had, I can't find any way to determine positions other than the one to start with. I ins...

Re: At a glance you may think this is a draw. White wins!

After you click the "Set value" button, you can set another position, etc. If you want to use a file, that should be a .txt file with FENs. The values are set by using the letters W, D, or L (Win, Draw, Lost) before every FEN string followed by '|'. E.g.: W|8/8/8/PkP5/1P4p1/5pKp/8/8 b - - 0 1 L|8/8...

Re: At a glance you may think this is a draw. White wins!

Humans cannot calculate all possible lines so how looking at it by myself can help? seeing the solution does not help to be able to practically win it because black can practically play a different move. For example 1.Ke2 Ke7 or 1.Ke2 a5 or 1.Ke2 Kd7 2.Kf3 Kc6 Impossible to calculate all lines and ...

Re: At a glance you may think this is a draw. White wins!

Critter needed about 8 minutes to find the winning move. I let the analysis run overnight: [D]4k3/5ppp/8/8/8/8/PPP5/3K4 w - - 0 1 Critter 1.6a x64, 4-Gb hash: 32/61 06:12 2 957 072 190 7 947 965 0,00 a4 h5 a5 Kd7 a6 Kc7 b4 h4 Ke1 Kb6 b5 g5 Kf2 g4 Kg2 g3 Kf3 Ka7 Kg2 Kb6 32/61+ 07:38 3 656 933 988 7 9...

Re: Continuation of Critter would be very appreciated

One year without updates is not necessarily much in the chess engine world. The situation is much worse with Ivanhoe, which seems to have been abandoned completely. Maybe Richard Vida has other things to do (like, you know, make a living) or is no longer interested in trying to make Critter the stro...

Re: First Strelka 5.6 Results: 4, 100-Game Matches!

Georges, two questions:

- Does Strelka 5.6 give "weird" evaluations like 5.5 did?
- Do you have any information as to a possible release date?
