Should I accept my opponents draw offer

Of course you were wrong. Being up two pieces , your move to really throw him off was to immediately resign!

Did you gain or lose points from this draw?

If you are up those pieces . . .NO! . . .
Swap as many pieces as you can and you wil win in the end . . .

You sure he wasn't English and offering you a draught? (I.e. Beer)?
To beer or not to beer ?!
OK ! .......I’m up a Queen and a rook , and my opponent offers me a draw . It was like a bolt from the blue ! And in my surprised state of mind , I accepted it ! ...... was I wrong to do so ! 🙀
