At the beginner level, it's fine to play on to the end as it's always possible your opponent could mess up and give you chances to either win or draw.
Now, as you progress through the ranks and make it to the higher levels, playing on in a completely lost position can be considered rude and I don't recommend you do it. It's essentially saying to your opponent that you don't believe in their chess skills to convert.
Now in this game... I decided to resign in a winning position. Is that rude? Idk
Thanks for the content.... Respectfully disagree though. I don't think it's ever rude to not hand your opponent a win. Players of all caliber mess up all the time (for example, Fabi missed a completely winning endgame vs Magnus in the last WCC). Not to mention some players are famous for their play in worse positions (like Frank Marshall).
New to chess.
If my opponent has taken an early advantage e.g. in material, is it considered rude to resign and avoid a long drawn-out probably foregone conclusion?
Thanks
It's never rude to resign. I'm happy to take any sort of win
The correct time to resign is when you're losing and you have absolutely no possibility of counterplay. Also if you blunder your queen away for nothing you should resign.
Otherwise, it's right to play on
