At my level or even at level till 2200, people will regularly make inaccuracies(positional inaccuracies) and it won't matter since the other person isn't good enough to notice and exploit it. The games are decided based on blunders, that's the end of it. Just like in my last game i made inaccuracies and so did my opponent but it didn't matter before the big blunder he made.
In short, just don't make blunders and the only way to avoid it is to practice visualization and calculation. Nothing else matters at this level, blunders are what decides games
... and who has the greater odds of making that critical blunder? The mid-rated player who is under serious pressure, or the mid-rated player who is applying pressure?
This idea that positional advantage is meaningless below GM level is, quite frankly, idiotic.
My point is, at below master level all one really needs to do is to not make blunders and he will be good to go. You don't need strong grasp of what to do in a position. You just need basic, very basic opening principles and that's it. You can keep on making "ok" moves and as long as u don't blunder, you will win
Then why are you only a 1700?
One point that you seem to overlook is that we are talking about Human beings, not engines... and in games between real people, bad positions tend to generate bad moves. Very few people continue to play as strongly when under serious pressure as they do when in a commanding position.
This is one of the reasons that tactics tend to flow from a superior position... the simple fact that accurate moves are easier to FIND when you are the one applying pressure, rather than being under pressure yourself.
Another obvious reason, of course, is the fact that winning moves only exist in winning positions. That's one of the things that MAKES them winning positions.
Well that is simple to answer, i am only 1780 because i make tons of mistakes... however if u are looking for words from an actual GM who has been coaching for decades, i suggest taking the words of ben finegold. He has said that in a game between low rated players, both players play badly until one player makes the worst move of all times and then he loses.... it cannot be more accurate than that.
