Black to move and save the knight.
Black has just played 1. ... h4 and white answered 2. O-O-O
This is a problem of the strategical module of PCT. They just asked for the move 1. ... h4. When you have found that move, Tchekov Mattenovitsch comments "In order to help saving the h1-knight" and goes on with the next problem. The repetitive system helps you to memorize the answer and that's it.
But now I have restarted with the strategic module of PCT, I want to do it in the new way we have discovered the past months, using narratives, generalisations, focussing on the solution in stead of the problem and visualisation of the solution. White has two main ways to pick up the knight at h1: with g3 and Bg2 or with O-O-O and removing Bf1. I am here investigating the latter situation.
What is especially interesting in this position is the chain of protectors:
- Knight f3 is pinned against rook d1 and is thus fixated.
- g2 protects the knight on f3 and is thus fixated.
- Bf1 protects the pawn on g2 and is thus fixated.
But how strategical is this? I can't blame Glenn Wilson if he would say "this is pure tactical". But no matter how you call it, learning to see such chains is very important.
