Tactics - Mistakes

Ok, Just a small document, but I came across this as a reason (4.3) for making mistakes:

4.3. Unfixing the intermediary positions in mind when calculating ahead is another
source of errors and it is often incorrectly associated with a weak capability to see in
advance. Many players think that they are not able to correctly see the positions after
some more moves ahead. In fact, at least half of them have another problem: impulsive
thinking.
Many students do the following psychological mistake: they try to prove their selves that
they are able to calculate quickly. However, this ability will develop only in time and not
over-night. So, the student is advised to keep a strict discipline when calculating branchy
lines ahead.

Can anyone translate this into something I can understand? I have no idea what it means.

Of course this is just a guess, but I think that they are talking about stopping the analysis too soon and not checking all of the candidate moves in a variation.

In fact, after your comments on visualization I was wondering what the purpose could be for calculating "all" of the knight moves from a1-h8 and came to my personal conclusion that they are trying to teach the tenacity to be able completely think through a problem - no mater how long it takes!

Well I won't be beaten, so it's a bit annoying to 'have' to do it. I think the real point is to practice visualising the moves. It's working, I find it is taking an impossible [to manage] amount of time, but my mental visualisation is DEFINITELY improving because of it.

I think they are talking about not calculating slowly and failing to clearly fix the position in your mind. Agree it is bit vague, but they're saying don't rush your calculation, rather make sure that you take time to fix key positions in your mind. This is similar to the ideas of Tisdall and Aagaard relating to stepping stones in long lines, where you calculate for a certain number of moves, then fix that position in your mind. Then re-start your calculation from the fixed position.

I think one can translate it as,

Not seeing the position clearly or just in the mind is another form of error, which one associates misstakenly with weak calculation skills. Many players think that they are not able to correctly see the positions after
some more moves ahead in calculations. In fact, at least half of them have another problem: characterized by undue haste and lack of thought or deliberation thinking.

Many students make the psychological mistake that let themself think they can calculate quickly. However, this ability will develop when doing time after time for a very long period of time and not in one two three. So, the student is advised to keep a strict discipline when calculating branchy
lines ahead.

Ah... yes, that is a distinct possibility. Thanks 'tiger :-)
