Typical MB patterns and ideas
1- Queenside development
How to develop his queenside minor pieces is one major concern of the MB player. The example above, taken from the Taimanov variation (A 67), shows how to solve this problem satisfactorily. White has just retreated his white-squared bishop from b5 to the aggressive square c4. Normally b6 is not such a great square for a black knight, especially if it blocks the b-pawn. But in this case it is a tempo gainer that allows Black to smoothly complete his queenside development. So 1...Nb6! 2.Be2 (or Bd3, Ba2) 2...Bg4!, and now Black is ready to answer 3.a5 with ...Nd7 and stands well prepared to meet any White actions. Thus he has solved satisfactorily the problem of developing his queenside.
