PV Rate Dropping to -2000 When Engine Suggests Resign #507

Closed Quisette closed 1 year ago

Please refer to the graph below.

When the game has checkmate, USI engine will suggest "resign", like this:

However, the PV shows nothing to display (in ShogiGUI, it will show "resign").

And the rate has dropped to -2000:

Is this considered a bug? Thanks!

In this case, sente wins the game by checkmate.

Thank you for your report!

And the rate has dropped to -2000:

ElectronShogi can not read score mate -0 correctly. I will fix it.

However, the PV shows nothing to display (in ShogiGUI, it will show "resign").

This is the different problem. pv resign is not defined in http://shogidokoro.starfree.jp/usi.html I think it is extended representation of ShogiGUI and YaneuraOu. ElectronShogi does not accept resign in PV.
