The Chigorin Defence tends to be the sort of opening that is better for White in most variations, but tricky and often underestimated (take "betters players", for example, who think that White is clearly better in all variations).

I agree that objectively the Chigorin is inferior to Black's more common defences to 1.d4, but it is not easy to face against a well prepared Black player (as Morozevich has shown). My advice would be to study these 2 books: The Chigorin Defence by Morozevich & Barsky, and Play 1...Nc6! by Christoph Wisnewski (I think these were covered in a previous thread). If you have a few improvements in the main lines, there is no reason why you can't score well with it. 

One word of warning: If you don't like tactical complications, or if you are not a very aggressive, attacking player, then this is not the opening for you.
