The key element there is "crazy laggtard". You made a read-dependant play, not one that is generally advised. That doesn't really prove anything besides the fact that reads override standard lines.

I check either the turn or the river there. Might even check the flop. Reason I might not cbet here is that I didn't totally miss the flop (as in, my hand might very well be best, but weaker hands aren't too likely to string along if I value bet), so I can still extract value from weaker hands or bluffs.
