I have two questions about a recent game that I played on Lichess.
Why is it necessary for White to push d5 now in the game, in this position, and why is Be3 a blunder?
Why is e2 the best position for the King's knight, and not f3 in the next diagram (on move 6 by White)?
There does not appear to be any annoying pin of the knight on f3 by a bishop on g4. Plus, I do not think it is disadvantageous to have doubled pawns on my position(if needed I could play Bd2 when Black plays Bb4). Lastly, and more importantly, the knight on f3 can jump to e5 if possible.
