Just for fun:

[D]r1bqkbnr/1ppp1ppp/p1NB4/4p3/4P3/5N2/PPPP1PPP/R1BQK2R b KQkq - 0 1

type d here -> nothing happens
dxc ->takes the knight
d7 -> moves queen to e7

[D]r1bqkbnr/1ppp1ppp/p1B5/3Rp3/4P3/5N2/PPPP1PPP/2BQK2R b Kkq - 0 1

d -> Bd6


[D]r1bqkbnr/1ppp1ppp/p1BR4/4p3/4P3/5N2/PPPP1PPP/2BQK2R b Kkq - 0 1

d -> nothing happens!
d7 -> Qe7
