I was fortunate enough to get a pair of games against CCIM Ronald Weyerstrass. I was destroyed in short order.
The best tactician I've ever played against is definitely sarthe (from this site). Maybe not 'stronger' than Weyerstrass but I'd say a better tactician. Although having a rating similar than mine he destroyed me in very short order.
The hardest opponent I ever played is my chess teacher. I'v only played 2 games with him, but he demolished me at both of them. The first one he forked my queen with a discovered check. The next one was too horrible to even talk about...
