Chess Fans have said: Quite an interesting topic and delivered in your usual flawless manner! The difference in rating points may not be a linear effect – but more like exponential. We have all been at one time or another the ‘mouse’ in a cat’s game. Only Ivanchuk is more like a lion! Thanks David!
