I don't know why I thought so, I try to explain why I thought so.

It sounds a silly argument even to myself; I feel I have not got it quite right.

Added to which it was not my partner who played the two of clubs, it was Dummy.

If I had only remembered this, and had concluded from it--as I ought to have done--that my partner had the ace of diamonds--as otherwise why did he pass my knave ?--we might have saved the odd trick.

I have not the head for bridge.
