So I've read through beginning alg topology really fast and there are a lot of theorems and methods for computing fundamental groups but what are the most useful tools? When asked to compute the fundamental group what should one do? try to find a deformation retract and compute the fund group of the retraction instead? use seifert van kampen immediately? what other practical methods are there for fast computation.
