again, you don't seem to understand the original point which was: if you already see a mate in a few moves, is it bad form/poor sportsmanship to traipse around the board taking everything instead of going for the quick mate which you've already figured out. and MY answer is: absolutely, unequivocally and in all other ways, a resounding YES--it is bad form, not gracious, not elegant and a sign of immature, poor sportsmanship. and that's irrespective of the players' ratings and all those other red herrings you've thrown into your previous rationalizations.
"extra brain atoms" indeed--lol ! where does one come up with this stuff?
Lots of laughs you should use extra brain atoms to aim for the quickest and most efficient kill. Sorry but in some posiions it makes little sense to do that. Usually an abolute statement is a sign of not knowing alternatives.
