It is a nonsense that all phases are equally important.Because understanding begins in endgame and openings have nothing to do with understanding.You don't understand chess with openings.With openings you only put the game on the auto pilot.
I've made it to the 2100-2200 level without studying openings or endings. Now that I've begun to study both, I'm learning more about chess and strategy than I have before. So yes, I agree that there's knowledge to be found.
Though, I disagree with you when you say that endgames are about understanding, and openings aren't. Both aspects of the game contain insights that are, in my opinion, invaluable.
Really, opening moves and endgame moves are one in the same. The endgame is just an extension of the middlegame, and the middlegame is just an extension of the opening.
Moves are move. You play them the same (by thinking ahead and finding what you believe to be the best for your position), regardless of what phase of the game you're in.
Both involve logic and purpose, and a good player plays each (and every) move for a concrete and thought-about reason. Even move one. Even move sixty.
You can disagree with me as much as you want.
The truth remains.You are jut unable to comprehend it and you have never seen it in action.I have seen how beneficial endgame training is for kids , have you?
You are just an ignorant(we all are more or less ignorants) that could be a much better player if he had focused on endgames.
There are cases of players that either with endgames or without they will reach the same point and will stay there forever.But if you had any chance to go much higher much faster , you simply have wasted it.It's a difficult to accept but sad truth.Of course you might never cared.Chess might be only a hobby and you became good because you were extremely talented.
Dvoretsky says that even grandmasters improved their results with the study of basic endgames.Pay attention to that.
With the study of ONLY basic endgames.
Imagine what basic and advanced endgames can do to beginners.
Another problem is that endgames need intense and focused multi hour study.You can't fool around like you can do with openings.Most amateurs are simply unable to do correct endgame study while you don't need to be especially focused to memorise lines.
Openings win the battle over endgames every time.It's a very unfair battle because endgames is an uncut diamond that only very few experts can appreciate while openings are a shiny glass, impressive in the eyes of ignorants but fake and without real value.
The fundamental truth that openings have nothing to do with chess understanding doesn't change.No matter what anyone thinks or says.
And what is your OTB rating ? uscf and/or fide ? I am curious to know just how far your focus on endgames has taken you ? I don't focus on endings more than openings or middlegames/tactics and have only made it to NM , state champion ( twice ) and have won against professional players in tournament play ... you ??
here is another one I like, watch what happens when black tries to keep the opposition but cannot at certain points for fear of leaving the square of the pawn.
Black draws easy after Kc8, he can chase down the back pawn and queen first
You'd better check before you post nonsense - it's a forced win for white (and a beautiful one).
I study endgames because I love them, I don't study openings because for me they are boring (although I get some opening knowledge from opening explorer in daily chess and from annotated master games)
