Viswanathan Anand went to meet his friend Garry Kasparov, but when he was about to reach the main gate, Anand notices that Garry had a mighty dog who was fastened to the tree. The chain is long enough that it allows the dog to reach the main gate.
How can the Anand reach the main gate?

Vishwanathan Anand ran around the tree in circles and the dog followed him and dog eventually wrapped himself around the tree. As a result, the dog cannot reach the main gate now.
