Does fair play really exist in chess?

I put in this area (Off-topic) why is this just for a debate, does Fair play really exist in chess or is it a bad joke?

In move 44 my opponent no have more pieces on board, just three pawns and one king. I have a Rook, a Bishop and a lot of pawns. Him have 1 minute in o'clock, i have... 13 MINUTES (!!!) with 10 seconds of increase. 

Fair play really exist in chess? I'm very sad, why we try so hard to play reasonable chess (even with an absurd amount of errors due to my low technical level) and almost 90% of those who lose, insist on the game even if they no longer have a piece on the board. I am by nature a fast player, I almost always have 12-14 minutes still in the 40-50 move, so trying to take me down in time is no excuse. And again the title question comes up: Is there a fair play in chess?
