Long diagonal is mostly just another expression. The longest diagonals are the A1-H8 and A8-H1 diagonals. They are 8 squares long. The important things are to have bishops on open diagonals, where they are aimed at the enemy squares or pieces. I've heard in the description of a position, that this bishop is hammering on granite. That means there's a big clump of something in the way, and the bishop is not making any contribution to the game.
As I said, this is complicated, and I mean it's complicated for me. After you get your questions answered it might be very easy for you. I think Capablanca had it mostly all figured out after he watched two games when he was 4 years old.
@junocunerino so bishops are okay to have if you can put them on long diagonal but what of the night? And when to do bishop if not a diagonal? Is it ok to sacrifice for a pawn if the biggest one cant have/
@YGNR , the things I said are very general. To get to the bottom of all this stuff, would take a little coaching or books or something. Look at where the action is.
Knights are much better then bishops here. Since they fork newbies.
@bufferunderrunBut YGNR doesn't believe in studying so...
@YGNRI couldn't give you an answer that doesn't violate your no studying rule so I'll just say keep playing for a few decades and reinventing the wheel and and you might reach 1400 before you turn 60.
A bishop is worth more than a knight, the difference being called the minor exchange and being worth about 0.25 pawn according to Fischer and confirmed by Kasparov.
Try to checkmate a lone king with two bishops. Now try with bishop and knight. Then try with two Knights.
in endgames a bishop on e4 cuts off all squares of a knight on h4. The bishop is said to dominate the knight.
There are several great grandmaster games won just by the advantage of the two bishops.
You should develop Knights first. Usually these go to their natural squares: f3 and c3.
You should develop the king's knight first Nf3 or Nf6 so as to prepare O-O.
Where the bishops should go is less clear and depends on the situation.
You should develop the king's bishop first, so as to prepare O-O.
A strong development of the bishop is the fianchetto: g3 and Bg2, as the bishop then controls not one but two central squares: e4 and d5 and as it then is posted on the long diagonal towards Ra8.
@YGNR maybe read a book like "reasses your chess" it addresses those questions with examples. And in chess answers are "all things being equal, which they never are". Sometimes you do needt sac a pawn to keep you pieces in game
There is interview with Garry Kasparov, where he says Fischer considered Bishops stronger vs Knights, giving 3.25 value, Garry himself was giving value 3.15, but after seeing many computer battle games he would agree more with Fischer's evaluation of 3.25, having Knight worth of course 3.00 ;)
In opening... you have to know opening and not just throw pieces in some particular order, because that order might be exactly what your opponent prepared for. I don't think there is rule to move both knights first before you touch bishops lol Just learn the opening, it will tell you where to put what piece and what's the idea ;)
Magnus can afford moving Knights back and forth several times and still win... do you think he wins because he follows rule of moving Knight before he moves any of bishops? Naka many times opens with fianchetoing both bishops... so it's bad? :D he still wins. It is interesting to read about Bishop vs Knight, but in general if you are very good you can do almost whatever you want. There are chess principles, but hey the higher you go the more people seem to know them, so you will eventually abandon some of those principles. Look at the modern classical games of Super GMs, it is a mess on the board, one could say but what about chess principles...
