Correct promotion!
Problem: Every time it is your move, the program automatically promotes to a queen whenever a pawn reaches the eighth rank. The option of underpromotion is not offered, although you have deactivated the option "Always promote to queen" under Menu File - Options - Game.
A pawn is always promoted to a queen whenever the preset "Single click entry - Aggressive" has been selected. This makes sense especially in bullet games on the chess server, when you would not like to waste too much time responding.
You can always force the dialog for promotion by holding down Ctrl-Shift before moving the pawn to the final rank.
