Whenever we see an unprotected piece we must keep our eyes peeled because this is one of the most important ingredients of a combination.
As quoted in his Excelling at Positional Chess (2003), p. 159.
The choice of moves should not be made on an exact verdict of the final position, but on whether or not your position has improved or worsened.Jacob Aagaard
We always say, one day we will laugh at this. I always try to make sure that this one day is today…Jacob Aagaard
