Sir, Andrew Robson, immersed in bridge and seeing people as Jacks and Diamonds (“How to play bridge”, Mar 5), reminds me of a time when I became a bit fanatical about chess. Unbeknownst to them, I found myself doing that, but with people as chessmen. Friends would be at a table, and my mind was wondering whether Jack’s position vis-à-vis John would allow him to take him if he was a knight or a bishop. Very disturbing.
