A quote from Alekhine, August 2018 -
"IainGrace … I don't think I ever suggested that there was harm in posting before completion … merely that I don't understand why people do it. Pushmipullyu has offered one reason why he/she does it and, although that feels fairly tenuous to me, if it works, that's cool.
I agree with you that there are clearly no rules ... hence my facetious attempt to highlight that with a ridiculous example.
You've reassured me hugely anyway with the revelation that
you yourself have even posted before finishing. Well ... that's good enough for me."
Entitled to a an opinion, yes, sarcasm perhaps ok, but downright rudeness in response to upsetter and myself surely unacceptable. Not that, I imagine, Alekhine will care what I say. Perhaps someone upset his chessboard.
