Jose, No, everyone is not doing this. At least I am not. Admittedly I have played only one game where an underpromotion was an absolute necessity to regain tempo and obtain a "check" to prevent a checkmate to the other side. This was to a knight promotion rather than a Queen. And the game was eventually won with the knight promotion. I'm sure others have witnessed this on occasion also. Don't ask me to find and post this game. I don't know where or if I have it but I simply regarded it as "the program knows best" and let it go at that. The program was correct..........
