The performance of a game can be highly influenced by the costly equipments that are used while playing a game. For instance, the opponents dreaded the combination of a polo player and his favorite horse. It was one of the costliest horses of his stable and hence his favorite. Whenever he was on its back he used to hole two balls. In fact, he refused to accept a large sum of money when offered by an opponent as he knew it would be more costly for him on parting with his lucky horse.
It was not that something miracle used to happen whenever he sat on the horse back. His skills remained the same but his way of using them changed as he gained in confidence while riding his costliest horse.
