Originally posted by thingmakerA set piece game is a game where you set up the pieces in a different position than the normal start position. It's a useful tool if you want to practise a certain opening or endgame, for example. Set piece games are automatically unrated (the only exception are thematic tournaments, but you won't come across those as a non-subscriber). As to why someone would want to set up a winning position against strangers, I guess they just think it's funny or something. It's also possible that they don't know these games are unrated, or that they want to make it look like they have won lots of games (while these games are unrated, they still count as wins/losses). It is that easy to mess around, but you can take measures against it yourself - you can set your maximum game number to 0, which means that people can't challenge you (you can still challenge them, and you can allow specific people to override this rule by adding them to your buddy list). But if you enjoy surprise challenges from people you don't know, that's obviously not an ideal solution.
a Set Piece game? Explain further if you would please.
My ranking never was affected, so why would one want to do that?
What is there to gain? Its that easy to mess around?
