g3
H7 if you want it longer
f3 I think
g3 is a draw by insufficient material after Bxg3, dxg3, kxg3 and then bxh7
f3 followed by either bxh7 or be4 is my guess for white to keep an advantage
G3
If Black is extremely low on time and White has time then Bxh7 Bxf2, Kd2 Kg3, Be4 and just play clock.
If White is extremely low on time then g3+ Bxg3, fxg3+ Kxg3, Bxh7 draw
