A ♘

a ♗

By the way Atharva i am no longer playing on this account I made a new one in which i am 2000 elo

Horse if its in middle

Bishop if the horse is in corner

Single piece, knight. Pair of rooks, pair of bishops

B+N are almost always better than R. More common (especially beginners) is sacrificing a B+N for a R+pawn and that’s usually a mistake too. In that case, the B+N (6 points of material) is still usually better than a R+pawn (6 points of material).

There’s several reasons why, but as a general guideline, the two minor pieces (B+N) are better in the opening and middlegame when the rooks are usually still undeveloped in the corners of the chess board. As the rooks develop, then it’s a more complicated decision and finally in the endgame, with the open board (or at least an open file for the rook to belong at), then the rook might become stronger. Even here, the B+N is still sometimes better!

But every game must reach the endgame so "valuable in the opening" becomes moot.

In your diagram white is really good, just need to gobble that pawn on e file and get Q into the game. It is a main line, possibly Fried Liver or something. Idk

Not exactly. Of course every chess game has an end, but when I say “endgame” I am typically referring to a simplified position that’s either a theoretical win for one side and almost always with both sides lacking a queen. The average chess game is 40 moves. Anything past move say 30, has a real potential to be an “endgame.” If you’re before move 20, then you are almost always in the opening or middlegame stage of chess and that means the B+N will be stronger than the Rook (or R+pawn).

The line I put was a common-looking variation of the Italian Game with a delayed “Knight Attack” but it’s certainly not a mainline. As for the “Fried Liver Attack”, that’s a commonly misquoted variation of the Italian Game; that only refers to these exact moves in sequence:
