False draw claim using enhanced winboard gui
Posted: 13 Apr 2008, 09:10Good day to all,
Just to inform that Romichess P3K will claim draw on knkb position.
When using enhanced winboard gui with "verify engine claims" set, that draw claim is considered false and zero game result is awarded to the claimer.
The adjudication of enhanced winboard here is correct, since kn can check mate kb (side) and kb can check mate kn (side) - help mate.
Old versions of Deuterium also claims draw on this end position
Best regards.
