Humans have been composing original chess problems for over a thousand years. Now a computer can do it too. What was the machine 'thinking' when it came up with this? If this one is too easy or too difficult for you, try out some of the others. Some of these problems may be trivial for you, especially if you're a club or master player but bear in mind that chess lovers can be found at all levels of play. So do check out some of the other problems. You can probably find something more to your taste.
