Qc7
Many transposition are possible here. The Qc7 is immune from attack from a knight because the black a- and e-pawns control b5 and d5

Another natural move pair. The Qc7 prevents the e4-e5 advance

Playable because with the white king on the kingside, white is less likely to aim for f3 and g4-g5

idea f4
10...b5
Justified because white has not played a4 or c4, and after 11.a4, black can push through safely with b5-b4
