Put move confirmation on. It will save you lots of trouble in the future.
Also note with my rating of 2350 Noone will ever allow a take back as they think winning would give them so much rating.
I also noticed that having missing a rook or bishop genarally does not mean good things.
At 1600 level people will most likely blunder a piece back given enough time for example 30 moves
Didn't read the whole thread but also think you were the one being annoying there. If you ask for a takeback and it's refused, to keep asking is poor style. Same goes for draws or rematches.
