Does losing a piece mean losing a game?


I have to clarify that I do know that rook is referred as major piece. I just formulated my words incorrectly.

There are a lot of different things that can compensate for a material deficit. Even when it's a big material deficit.
But forget about being a piece down. If I'm a pawn down vs a peer in an otherwise equal position, then I'd be happy to draw.
And that was true many 100s of rating points ago.
One of my proudest games was drawing an 1800 OTB when I was 1600. I dropped a pawn on move 10. I fought like hell for that draw. The game lasted over 5 hours.

If a 1700-2000 accidentally loses a knight or bishop during the first 10 moves, resigning is certainly reasonable, even if it's a blitz game. Usually people play on a few more moves, but if there's zero compensation then they often resign.

You are correct to keep playing. It's usually bad to resign immediately.
In serious games I never resign immediately after I make a mistake, even if I blunder a knight or rook or queen.

If I lose a piece out of stupidity, I'll also resign, but where I'm in control, I could sac up to three pieces and continue on. It all depends on how much in control you are of your game.
Interesting. Losing a minor piece for NO compensation against a tournament player should lose the game; but. With Queens still on the board, the losing side depending on the care the winning side takes; might be able to force perpetual check. Also; if the losing side can remove all the pawns and pieces, a minor piece can't win alone. But it might be a long hard fight and chances to draw are slim to none and playing on is generally a waste of time; typically best in tournament to resign and rest so to play better next round, not to mention not insulting your opponent. One might continue to play knowing you're lost, but for practice of technique; and knowing low rated players do blunder away the advantage. I note the high rated players, when in winning positions; take their time and are very careful even before they make "obvious" moves. However, when the loss is crystal clear, the winning method obvious and undeniable, time to resign.
LOL, sacrifice is different animal, sacrifice isn't "lost piece". some of my best wins I sacrificed the exchange; and in two of those; simply sac'd exchange to improve piece activity; and improved position and piece activity eventually won. Combinations are often defined as starting with a sacrifice leading to forcing variation winning something, material, position, or game.
