I have played some bad moves in my time,but i think this is the worst.
I am black in this game,doing nicely,a piece up for 2 pawns.
King in the open,but i have to protect my queen side pawns.
I am not sure what happened but i played Re8!!!
White can take the rook as my knight is pinned.
Is this chess blindness or very careless play,or both?
