@contenchess saidJMHO - There is a fine line between a strong fighting spirit (which I support) and playing on in a hopelessly lost position. Thankfully, most players know the difference between the two.

@mchill saidTo an extent for me it can be good practice for getting out of bad situations, looking for combinations of moves in the correct order and on. It is annoying though if someone doesn’t have any way of defending or attacking and keeps playing or quits moving when their going to lose.

I have a different philosophy.
For whatever reason there are always going to be games where I am in a poor position
If I have got into that position through a silly mistake then it may be worth carrying on in the hope that my opponent "lets me back in" the game.
However,if my opponent has gotten himself into a winning position due to his superior play I deem it unlikely he is going to make a costly blunder.
In this situation I consider it a better use of my chess time to concentrate on the games where I have a chance so I will resign a " potentially lost position" accepting that my opponent has played better than me.
