user-1: I was recently surprised by the following drawing idea, black to move:
6k1/pR3pbp/6p1/1Q6/8/5nP1/PP1r3P/5K2 b - - 0 1

In this position black can play Nxh2+ and, no matter white's king move, move the knight back with Nf3 and make a repetition (or win!).
It is a win if white decides to run to the h1 corner because for example 1...Nxh2+ Kg1 2. Nf3+ Kh1 3.Rh2#. If instead white goes for the rook, then 1...Nxh2+ Ke1 2.Nf3+ Kf1 (only legal move) and we have repeated the position.
Is there a source where I can find a collection of drawing ideas like the above?

user14130: there are different books that cover this topic,
for example Neishtadt book on tactic " Improve Your Chess Tactics: 700 Practical Lessons & Exercises" has a chapter dedicated to miracle saves, which is stalemate and perpetual.
On John Speelman tactic book as well there si chapter on that,
I'd say many chess tactic books have a chapter on this topic generally.
