Chessabase, UCI and WB engines are different concerning a some minor details. In WB the engine has to do everything by itself, read the book, claim the draw etc. In UCI there is no way the engine can claim a draw, there is no protocol command available for the engine to do this. This is all documented and normal behavior, there is nothing here indicating Jonny didn't behave according to protocol or was lacking in some way. But all that tech stuff aside on who knew what and why, the crucial point remains that Jonny managed to bring about a draw on the board and the operator was allowed to overrule it only to face certain defeat. -S.
