Chalking the other player

What a delight there is to be had from this simple, childish act. Especially when your opponent is wearing white or some other similarly stainable colour. I have seen many variations, involving secret chalking, blatant chalking, and a recent discovery (which I think may have been invented in the North) called chalky finger, involving using someone's finger as if it were a cue and giving it a thoroughly good chalking indeed. Not quite sure how I fell for that one but I did. I also then accidentally chalked my clothing, giving me a double chalking.

Chalking the other player should clearly be introduced into the World Championships as an acceptable psychological tactic, especially against Stephen Hendry, who is asking for a chalking.
