My table tennis partner wanted us to ease off a newcomer. Should we change tactics during a competition?

We won 11–2 and 11–3. Whenever the newcomer was due to play the next return, we aimed towards his weak backhand. After the match, my doubles partner said, "You could see he was miserable. Why keep doing it?"

It was a recorded club competition, although the other pair had joined only that month. I wanted us to play properly rather than decide they needed us to go easy. My partner started sending easier balls late in the second game, and we hadn't agreed to do that.

The newcomer shook hands and asked for another game. I can't tell whether he wanted another try or was simply being polite. His partner said they'd learn from playing stronger pairs.

For the next uneven match, should we stick to the tactics we'd normally use, agree to practise something else, or keep the competition honest and offer a more balanced game afterwards? I don't want to make kindness mean secretly deciding how many points another adult deserves.
