Would you like someone to promote "their" pawn against you ??
Of course not! So just line up all your pawns on the 7th rank and leave them there looking stupid! Because it's rude to promote them.
Chess is not for the fainthearted. No point accusing any player of being rude. May as well just open 1h3 as White.
I love it!
If it is legal, play it. Rude is eating sticky candy and touching your opponents' chessmen with sticky figures, etc.
What does chess etiquette have to say about promoting pawns when I'm already ahead in material? Say a bishop and two pawns.. It seems safest and fastest for me (at my skill level.. about 1400 turn-based online) to win by doing that, but it seems like piling on. Would doing so irritate people? Is it insulting to keep your advanced pawns two ranks back deliberately? What am I missing here? Thanks guys!
Do whatever is the fastest and easiest way fo finishing the game. I've done it before because I was afraid of getting a draw by repetition if I didn't promote an extra pawn. It was nothing personal.
