The Knight that jumps high falls prey to a Pawn.
(Keima no takatobi Fu no ejiki)
Vocabulary: Keima=Knight, no=of, takatobi=high jump, Fu=Pawn, ejiki=preyBeginners invariably seem to love this piece which leaps forward in two directions. When played prematurely, however, a Knight can be easy prey for a Pawn.

But White will then play S-4b, aiming at a later P*4d. That will be one Knight of yours that falls prey to a Pawn.
If Black did not have a Pawn on 5g, you could play N-4e. After S-4b, you can drop a P on 5d, thereby you can exchange your N for White's S in the future. Material gain means a lot in the beginning phase.
Back on Diagram 1, you need to do something before playing N-4e. Which is...?
From Diagram 1: P-3e
P-3e is an important move to play here. By pushing a Pawn to be taken, you can drop a Pawn in hand on the 3rd file.
Moves thereafter: ... Px3e P*3c ...After P*3c, if White responds with Bx3c or Gx3c, you can play N-4e forking the two pieces of higher value. What if White plays Nx3c? Yes, P*3d. You've learnt a lesson.
