The Power of Knights
Here is a game from the 2008 Corus Honarary Group, GM Ljubojevic - GM Timman with full annotations and commentary:
This game is a nice illustration of the power of knights in closed positions. Both of the black knights were able to find outpost squares on e5 and c4 which helped him to take control of the position. We typically see the knights in a Benoni type game looking for outpost squares. If black is able to accomplish this then it may result in a good position and an eventual victory!
