I strongly agree with you! This is the profile of the "nowadays chessplayer" at amateur level. (up 2300 is or smth) Tactics-tactics-tactics openings-openings-openings and more tactics-tactics, etc with almost zero, but very limited endgame and/or positional unserstanding.
How to beat those players?
Learn some solid openings (not too many its a waste of time) which are hard to crack. Get your tactics at some basic level, so when your opponents start some tricky moves you sense danger. Learn a tons of endgame (not only theory, but aim for understanding), positional play.
When they cant beat you in 20 moves, they start to get frustrated. They offer a draw, because they dont like endgame, (because they didnt practice it). You decline, they have no idea what to do, and you beat them easily.
And this actually works, and its sad lol.

No doubt it is always important to help our fellow members and spread knowledge when we can. If someone is learning something and becoming better than yesterday, that is something that helps all of the chess community, and that is why it is so important!
So you are welcome, I am glad that it was very informative, and that you found all of these various people having informative ideas worthwhile, it is very important for all members that take interest and learn despite our differences, as the more we learn and apply the more we grow, so that is the mission.
Or at least one of them!
