I never did this so this is a topic I think deserves some discussion. Perhaps there has been some but I didn't search to find out. Here goes, probably common knowledge but maybe it'll help some peeps:
What is a weak lead? Also known as donkbet, when a player leads into the preflop raiser OOP. I don't consider betting the turn after calling a c-bet a weak lead though it's similar (slightly stronger play in my experience). This post is purely about the first concept.
IMO the best note you can take if how people respond to a raise after leading weak. Most players will fold to a raise, it's generally a medium strength hand maybe a small to middle pair that's trying to see how you react. Do not continue after a call without a strong hand, at least top pair big kicker (without a read or note ldo). It's rarely a draw or set, or any big hand.
When you first encounter it from an opponent raise ATC. Always. And take a note. Especially if you actually have a strong hand and get to showdown, then you can detail it better. This information is gold. It can take on any form from PSB to a minbet. Can be for value or just a bluff, either way finding out what this means is good and raising seems to be +EV either way. There are times when you may be crushing the deck and slowplay is best but very rarely.
