Checkmate!

You take your young grandson to the local park one balmy evening and happen to meet a charming chess teacher who is there with his two sons. The conversation flows and you are gratified to learn that he teaches little ones as well as older children so you find yourself contemplating enrolling your wee man and even considering taking lessons yourself. You are not convinced that the 'charm' is just that, because part of you suspects it to be tied to a sales pitch, but you realize that this doesn't much matter. You loved the words you exchanged with him and you have decided to try for more, sales pitch be damned...CHECKMATE!
