In some recent threads Korch and another player were complaining
about a players playing on in a clear draw.
In an OTB game I set up a blockade and was wondering why my
opponent had not accepted my draw offer.
He suddenly played 52. Kg5 (diagram).
I shrugged my shoulders and played....
52...Rg5+ only to see 53.Qxf5 gxf5 54.Kxh5!! 1-0
I had been diddled. (I#ve swindled 100's of players so I know
everytime I have to give one back - what goes around - comes around).
So sometimes ask yourself why the other guy is playing on.
There may be one last trick in the box.
