Rules are rules. Just like in OTB play. Sure it sucks to lose that way, but who knows? maybe your opponent was simply moving fast, wasn't paying attention, who knows?
What would i do? If it was a friendly unrated game, i would let them take the move back. If it was an OTB game? Obviously touch move rule applies, and as long as they didn't release the queen, they could move it somewhere else. If they had released the queen on the square, then that's their move. I will say that since this is a team match, and it impacts the team your playing on. No, i would not offer a draw.
So I'm playing in a daily team match, rated, and my opponent appeared to mouse slip his queen after 7 moves:
He immediately resigned. All of this happened when I was asleep, and I awoke to find a free win and 22 free rating points. My question to you all is what would you have done if you were me and your opponent offered a draw. This is a rated game in a somewhat important team match. A draw would have cost me about 8 points and would cost the team a free win, although it's possible I could have won later. In blitz it's considered polite (although not mandatory) to give a draw in a equal position after a clear mouse slip but daily generally allows you to confirm your move (although this feature can be turned off) and isn't nearly as hectic as blitz, where mouse slips are common. Because of this my first thought is that the player screwing up has much less of an excuse in daily.
On the other hand, I know that chess.com's app can be...problematic when it comes to placing the piece on the correct square, even in daily, and I almost learned the hard way never to use my phone to play daily chess if I consider the game important. On the other, other hand, I have no idea if my opponent was using the app, or what happened. Thoughts?
