This “online vs in-person” thread brings back an old memory. Sorry if a bit long-winded, but here I go…
Many years ago I played lots of chess. Occasionally, I would visit a local chess club - but not regularly.
One week I overhead an elderly Chinese man there lamenting that he couldn’t attend any more because the guy who drove him each week was moving away.
Clearly he was too frail to be driving himself. So I asked if he would like me to pick him up on my way to the club? He was overjoyed and bowed deeply.
Of course this now meant that I had to actually attend each week. Else this poor old guy couldn’t attend. My sense of guilt forced me to become a regular at the club.
So at the appointed time each week, I would pick him up from under the awning in front of his apartment building and he would hobble to the car with his cane in one hand and his weathered chess set in the other.
This went for a few years.
I’d alert him on those occasions when I’d be out of town on a business trip and couldn’t make it. He was very polite and extremely appreciative, but I could see the disappointment across his face.
Anyhow, along the way I discovered that he was quite the chess master. In fact, he was essentially the top rated player in the club. I learned this by eventually realizing that the top name in the leader boards was his. (I struggled to approach the middle.)
From a distance he would watch some of my games and then share pithy pointers meant to improve my game during our brief ride home. Much like in Go, these were Chess proverbs, but delivered in his broken English.
His “tips” worked wonders. My rank steadily improved when I recalled his car ride comments during my subsequent games.
At long last I accepted a job in another city and had to let him know I could not drive him any longer. However, first I arranged for another club member to agree to start picking him up each week. This kindly old gentleman would never have burdened anyone with such a request on his own.
On our last evening together, he said he was extra tired and asked if I could walk him upstairs to his apartment. When we walked in, his elderly wife bowed low and presented me with banquet of home-made dishes. The two of them sat me down and honored me with an amazing feast.
I can understand @Go_Prince_2021’s point: there are benefits of playing games with real people and real pieces together in the same room. The unique quality of human interaction is of significant value.
By the same token, the internet now allows us to enjoy each others’ (detached) company from afar - across time zones and national boundaries.
As such, I think of “complete” players as being those who bring their full selves to a game. The particular format then becomes besides the point.
