This is getting technical, more so than it has to be, I will try and explain.

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.
