As England and West indies slog it out on a sucession of batting paradises, we look back to a similar story in 1967-68 - with an unexpected ending. After three draws, the Fourth Test looked to be heading for another draw before West Indies' captain, Garry Sobers, declared at 92 for two - because, some said, he was bored. England were set 215 in 145 minutes, and got home with just three minutes to spare for the win that clinched the series.
