Gymternet:
The Tkatchev, named for Alexander Vasilyevich Tkatchev, is also known as a reverse hecht. At its most basic definition, it’s done from a back giant swing, involves a release backwards and over the bar, and is caught again on the other side. Where it gets interesting is the entry (i.e. from a stalder, inbar, toe-on, or clear hip instead of a giant) and then the body position in the air (i.e. straddle, pike, or layout). Here’s a handy chart I made to help with the variations.
