I have some doubts on what is ABC poker, if i take the pre flop chart of the 30-day course, and always open raise with then then fold if i hit nothing, is that the ABC?
ABC poker is about not trying to many fancy multi-street bluffs like betting all 3 streets, because the board runout is QsTs2s5h8c, and you hold AsJc and therefore block the nut flush. Having the nut blocker is relevant against thinking players. But it does not matter, if your opponent is a fish, who will call you down with Kh8s, because he was chasing after an 8 high flush and rivered third pair, and he is not going to be pushed around by you.
Its also about not slowplaying to much. There is no reason for instance to overlimp QQ to trap players behind, as I saw someone do in a MTT today. Just make the simple raise for value. Sure in this case it kind of worked for him, since he got it in on the flop as a 4:1 favourite against me, but he still lost the hand, which he was mad about in the chat afterwards. If he just pump it up pre, then I go away with JTs, which is a fine enough outcome for him.

Finally its about not assuming, that your opponents are paying a ton of attention to, what you are doing, and that your "table image" is therefore very important. As someone recently wrote in another thread, maybe they have been watching porn videos the whole time, so it has completely missed their attention, that you have hardly been involved at all, because you were card dead.
Or in case of regulars they are often playing so many tables at the same time, that they also dont have time to keep track off, what everyone has been doing, unless it was in hands against them specifically.
