Investigation continues

Polgars book has 77 chapters with 54 problems each. Each chapter treats a specific middlgame theme. I'm busy with the chapter that is called opening up the diagonal. The problem that I studied today contains the following elements in the main line:

  • knight sacrifice in order to lure the king in an ambush
  • pawnfork at the same time opening up the diagonal
  • counterattack by the opponent
  • setting up an ambush
  • discovered attack
  • trade of rooks
  • exchange sacrifice
  • trade of bishop decoying the king
  • double attack winning a rook
Endresult: 2 pawns up from which 1 is a passer.
So you sac a knight, 9 tactical motifs and 20 ply further you regain your material with interest. Every tactical motif has to be checked for all alternatives. A grandmaster can do this, otherwise he hadn't sac'd the knight in the first place. I try to imagine what is necessary for me to learn to do the same.

Problem 388























Black to move and win.
