g3 would indeed be much better for white, as far as I can evaluate. But Kd2 was the first valid move, and that's what I assume to be chosen as per specification in the save. I am open to g3 being played too, though, that would make the game more interesting.
Honestly the Pg3 (g2 to g3) move is what I would prefer but idk what Admiral_Awesome is going to choose
Assuming Kd2 (e1 - d2) is played, I propose Qg5 (d8 - g5).
@BLUE-User you can't do that the king is being threathened.
@TheNik: Done! White's move.
