Now, where was I ?
The whole beancounting stuff started with this position below. I wanted to know what the effect is of bishop b5. While I investigated this position I noticed that my mind was filled with visualising the move sequence while bookkeeping for both sides. The invention of the beancounting method was meant to relief the load of the short term memory. I obviously succeeded in that. The next question is of course, what is the effect of the bisshop on b5? Can I simply say that due to the duplo-attack Nc6 is pinned so black has one defender less for d4 hence white can simply take on d4? If so, I have found a way to judge this position without visualising one single move and without any burden of the short term memory. That's the holy grail I'm after. I got a bit carried away by the beancounting stuff. But it's only a little part of the equation.
White to move.
Let's see if black can save his victim. If white plays 1.Nxd4, black must answer 1. ... Nxd4. That is is only chance to hang on his wood.
Let's see if that is enough. White has invested 2 pawnpoints. If 2.Bxd7 takes away a defender of the knight while getting the investment back. 2. ... Rxd7 It's hard to think of another move since there is no viable duplo-attack for the black knight.
Which means that the knight is lost, which means that black must abandon his pawn on d4 at move 1.
Conclusion: Beancounting without the bishops shows that d4 is just enough defended. Bb5 is a duplo-move which pins a defender, hence white will win the d-pawn.
This means that this position can be judged in a glance without any necessity to see the move sequences before the minds eye and without being a burden for the short term memory. It was my hypothesis that a grandmaster solves this kind of positions without calculating. What is proven is that it is allowed to draw conclusions about this position without any calculation (in the usual chess sense).
At the moment I need these heavy narratives. As Blue Devil pointed out, that are only the training wheels for the moment. Once this kind of thinking becomes a habit, there will come a moment that I don't need them any more. That's what I'm after.
In the next post I will have a closer look if the Nxd4 move loads up another duplo-attack (discovered attack).
