I think you are right but it would drain a lot of energy from me to keep
concentrated enough to not miss 4 or 5 plies tactics.

It is strange because programming is a little bit like that. When you want to
make a change in a program it's like computing chess tactics: you have to
foresee all the consequences and all the places where some change is going to be
needed. And I'm not too bad at this.
