This is a key position. Both sides have even material. White has a small edge due to better piece development and location. It is White to move. I suggest you to do a few things to improve:
1. If you have a friend who plays chess, take White and play to win. If you do not have a chess friend, set your computer level to strength appropriate and play against your computer.
2. After you understand how to win as White, reverse color and try to hold as Black either against your friend or computer.
This is a good exercise to do. Have fun and good luck!

An excellent exercise with guidelines. Thank you!
I like
1. Qc3
if 1…Re8 then
2 Rd5 f6 (…e4 then Bxe4)
3 Qc4 Be6
4 Rb5 Qa6 (…Qd8 then after Bd5 Qe7 white wins the b7 pawn after liquidating)
5 Bd5 and I think white wins a pawn
if 1…f6 then
2 Qc5 Qxc5 (if …Qxb2 then Bd5+ wins the bishop)
then white has the idea of Rc7 and R1c1 and the b7 pawn falls.
maybe – i’m the dumb one – but i found no clear win for white – there might exist a winning plan – but it depends on blacks answers – no doubt – black has a difficult position – but it is not yet lost …
the variations are too long and too complicated to post and to think about in real matches
1.Qc3 Re8
2. Rd5 f6
sounds good
but there is no easy / forced way for a white win … (the way i see it!)
thus – attack pawns – the weak pawn on b7 and the pawn on e5 to make black weaken it’s white fields (with a nearly doomed white – fielded bishop) and to create a new weakness on g7 could be plans created by me (i am an amateur … but enthusiastic :))
