RE: These are the two only chess openings you need to know!
Hi, I'm a chess fan, personally I don't recommend learning the openings if you're not good at it:
Now how do you become a good player?
a) Doing checkmate exercises in 2, 3, 4 and up to 7 moves little by little these calculation exercises will be very useful.
b) Perform endgame analysis, this is what gives you the level of a good chess player.
c) Study Alexander Kotov's books of training methods, they are really good.
d) Once you get into the habit of doing exercises as a daily training, and some reading or playing of some player and analysis of it, you will notice a considerable change.
e) Study 2 openings for White and 2 for Black, one with e4 and the other against e4, d4 and against d4, mostly analyzing games with those openings, as much as possible.
f) Try to do blind exercises or play blind, i.e. without a board.
h) Play in the tournaments you do @schamangerbert:
