Play for a love of the game not a love of winning. If you get to stuck on "oh man I have to win this game" you will make single ply unelegant and obvious threats. If you really do not like chess and are playing out of some family thing then by all means give it up. But if you enjoy the game and truely love chess, then the second you forget about winning, you'll have just won.
This is (Tal) the truth
There are a few possible reasons for playing chess, in my opinion:
These are the only reasons i could think of to play chess. There are many reasons to play chess as you can see. If you believe there is no point in playing chess for whatever reason, there is nothing wrong in quitting chess altogether. It doesn’t make you less of a person for not playing chess, just remember that. I quit chess, as i couldn’t find a reason for playing chess anymore. I used to play it because it was fun for me, and i wanted to reach a certain rating, but within time, it became less fun to play, and reaching the rating i wanted became pointless to me. So i stopped playing chess, forever.
I hope my answer helps anyone whom cannot decide whether to continue playing chess or not.
