how to get over the 600-700 elo range

hello guys,

i'm new to forums in any sort of online community and this is my first time ever i'm posting something online.

for quite some time, i've been stuck to 600-700 range. earlier when i was stuck below 300 elo, gothamchess videos helped me a lot but now i do not have the time.

i would love a few advices and suggestions for me. i would love to know if there's some opening that is should know and play or an endgame tactic.

here are a few games i played i consider them my best as of now (not that i've won 'em all):

"i've been stuck to 600-700 range" ++ A rating of 700 is a sign of frequent blunders.
Always check your intended move is no blunder before you play it.
Hang no pieces, hang no pawns. Sit on your hands.

"some opening that is should know and play"
++ Do not worry about openings.
You do not win or lose because of the opening, but because of tactical errors.
Simplest and best is to defend 1 e4 e5 and 1 d4 d5 as black and to open 1 e4 as white.

"an endgame tactic"
++ Start practicing the 5 basic checkmates: KQ vs. K, KR vs. K, KBB vs. K, KBN vs. K, KNN vs. KP. Learn first 3 men endgames like KP vs. K, then 4 men like KQ vs. KP, KQ vs. KR, KR vs. KP, KR vs. KN.

than you very much. i will keep this in mind

Watch John Bartholomews 'chess fundamentals ' series on YouTube. You'll jump hundreds of points. Just read the comments. I'm rated 1410 now have been 1499.

You should learn most important principles of a chess game. That will give you a solid understanding of a chess game and you will know what to do in every position. Then, you should optimize your calculation so you don't miss tactics in your games. Your rating will skyrocket. I can help you with all of this. Message me if you are interested.
