Black to move.
In my belief to follow mr Nimzowitsch, I tried to stop whites attack by bolstering the center by playing 13. ... Bb7 here. Since the preconditions of a kingside attack are met here according to Vukovic, I was immediately lost. Whites pieces are outnumbering the black pieces by 3 on the kingside while the center is stable. (Standard recipe: trade the defenders, sacrifice then 1 of the 3 extra pieces to open the kingposition while the 2 other extra pieces deliver mate).
You can clearly see that I'm experimenting with the idea's of My System:
- I traded dxe4 since a center square can be occupied by a piece just as well as by a pawn.
- I opened up the d-file in order to get an outpost on d5 and to get pressure on d4.
- I aimed my pieces at the center.
- I attacked the base of whites pawnchain with my b-pawn. In dorder to undermine d4.
In fact this is a very important position to analyze. It can happen in all sorts of openings where black plays d5 and e6. Basically you hand over the keys of your kingside to white and wish him good luck. Most of your pieces are cut off from the defence so you must have a plan B when whites starts to murder your king. For years my plan B consisted of avoiding systems with e6 and d5 all together at all costs. The reason I got into this position is that for some openings I'm sitting between two chairs. I renounced all gambits but against 1.f4 I haven't an alternative yet. So I based my moves on logic in stead of rote memorization of variations. Since my logic is based on insufficient knowledge disasters can happen, occasionally.
The past years my adagium was "piece activity". That helped me to avoid such disasters. But now I want to understand the center and its relation to piece activity.
