two the importance of pair

And god said to noah gather two of every animal.The importance of pairs is so  valuebaI in chess

 I think one of the best defences involes two bishops and two knights to gether.YOU will be very good at chess if you learn to manipulate pairs.The bishops can be vary deadly if paired to gether combine this with a two knights and you have one of the deadlyist defences.Also with to rooks you can an easy check mate.As you can see pairs are a very important part  of chess.I personaly think you can not be a chess master until you master pairs.
