Sauce talks about it and uses it sometimes, but I dont think its a subject worth a dedicated vídeo, so there are none. Basically you want to develop leading ranges on board textures/cards that hit your range harder than your opponent's, because villain will be checking back pretty often and you dont want to let him realize free equity. Im not am expert by anyeans but its not something you should be dedicating time if you are still playing low stakes since such strategies wont add a ton of EV to your game

Unless you're either crushing 200NL or playing much higher you shouldn't be bothered with donking. It's one of the easiest things to misapply and hurt your win rate, and the potential gain is quite small. At smaller stakes most players are too aggro in the spots you should be donking anyways.

like mentioned above donking isn't something to work on in the smaller stakes and very few information is available. Personally I do think there are a few spots we should incorporate donks on the small stakes:
1) vs players who aren't betting themselves.
2) vs players that float too wide but are passive.

example: 1)
villain who checks back bottom pairs, gutter+overs, flushdraws, OESDS, weak top pairs ( so bet for value when you are ahead of his range)

2) passive fish who float QTo on A83 boards for example. or Ax on coordinated boards like 68Jr etc etc

Most important thing is that they are passive as we're giving away our bluffcatchers.
