Attacking Methods 3 w/ GM Hellsten

From a channel Lumen includes in full: Every sampled title is a structured chess lesson taught by a GM or IM, covering endgames, pawn structures, attacking methods, opening systems and game analysis. All six available transcripts are dense, interactive classroom instruction rather than entertainment. These are recorded classes, comparable to lecture recordings, not casual streams. Sponsor and course mentions are brief asides within otherwise purely instructional content.

A 74-minute video from U.S. Chess School's catalogue; the title names its topic.
