You can post a picture by using the little icon that looks like a tree. (You have to save the picture somewhere first to be able to upload it.)
You can use the little chessboard icon tool to post the position. If you have the pgn score of the game, you can post the whole game or , if you don't, just post the position you are talking about.
The computer recommended I give away my rook and then my night to go on to lose the game. I backed it up and it changed its mind after the third time and didn't give away my rook. I'm finding flaws all over this site! I'm spending hours in study thinking the level 10 analytics will show me the best moves. I'm positive it showed me bogus moves and it put +3.5 in front of the rook give away? Like I said, I played it out and then it gave away my bishop, and then lost all my pawns. I took a pic but don't know how to paste a pic on here. My question is why is the computer analytics messing up???
