Politiken Cup

Here is a position from a game I'm following in the Politiken Cup (Shandorff vs Harvey). Black offered a rook sacrifice with 1. ... Rc7 and I couldn't work out the mate if White accepted it (he didn't) so I plugged it into an engine. To my surprise there was a mate - but for White!

Timman is participating again.
He won in last round aganst Harvey, who made mistake in 41st move.
