(That is the form I learned from John Huang and still enjoy practicing.)
I also found silly videos about how to use Tai Chi in combat.
Of course, Tai Chi does have actual historic fighting applications. Here is an video with some examples. But most American practitioners do not study it in that manner.
I like doing some Chen-style Tai Chi because I like the feedback from slowly doing the movements to feel how I am making very slight but still noticeable improvements.
In Jiu-Jisu, an equivalent slow, attentive, and studious practice that focuses on one motion at a time requires a partner. It is named the Chess Drill.
