Bad openings are punishable. Whether your opponents can or not is another matter. It still doesn't help to play objectively bad moves. Ideally your opening moves should lead in to your middle game strategy...so there may not be much value in learning a bunch of lines; but there is a lot of value in playing something reasonable rather than random moves. Generally though, in opening advantage gets thrown away pretty quickly when us patzers play. I actually spent more time studying typical middle games from openings than drilling move orders and lines, and that actually had some payoff (now just gotta learn to win won games).

You have more important things to deal with, like not dropping pieces.

Yeah I know it would be more useful to study middle game from an actual common midgame position, but what i'm looking for is just to have to actually think, starting from move 4, instead of waiting 20 moves for the position to get sharp. It's that thinking which really please me and make me enjoy playing. Also i'm talking about 3:2 Blitz, in longer time control I think i would actually be punished.
To each their own. I prefer to just get out of the opening in tact and in a good position so I can start the real game (rather than waste time figuring out basic development and the like). I'm perfectly okay taking 20 moves to let things get sharp. The longer you hold the tension the greater the chance for a satisfying resolution, or at least that's been my experience. I also spar with computers a lot (and lose a ton against them), so I tend to favor making sure the moves I play are actually doing something having been punished thoroughly many times. But yeah punishment at 3|2 probably isn't too likely; a lot of players just push wood for the first dozen moves at that speed.
Hello,
I just wanted to share that I recently started to change my state of mind toward my rating on this website, and focus on improvement in the middle game over my elo points. Since I chose to not care anymore about my rating I started to play the most terrible opening ever, my first four moves being completley random, to then see how I do from there.
Now the funny thing is nobody know how to punish me, my winrate is the same, and I didnt even drop in elo. It seems that the opening does not count, at my elo; doesn't matter at all, zero importance, nada.
We're so bad lol.
Sorry if the quality of the post is arguable, it's just something that made me have a good laugh realizing it.
