ok i have a question with regard to pins and there effectiveness and when we should
use them as a counter attacking manoeuvre. You know the thing i mean, we have
a knight on f6 and it gets pinned by a bishop on g5, or a knight of f3 and it gets
pinned by a bishop on g4 and we play either h6 or h3 and the bishop moves away
to the h file , while still pinning our knight and we can play either g5 or g4.
when is it appropriate and under what circumstances to play ...g5. The reason I
ask is that when i was going over Fischers games i noticed that in many
instances he did not care about the holes in his position that such a manoeuvre
produced, but he used the ..h6 ...g5 manoeuvre to trap the bishop and exchange it
for the knight that was formerly pinned. This happened on not a few occasions.
