user1120: I'm playing a game against a chess computer as white, my move:

I'm struggling to work out what I should try to do. I am up a pawn. I've managed to force the black king to move so it couldn't castle and the rook on h8 is stuck.
My pawn on c3 is looking vulnerable.
Where do I go next, what should I be thinking about to press the advantage into a win?

user11144: Your advantage is smaller than you think. After Kg7 Black is safe
and has joined rooks. The pressure on the c file is annoying and
ties up your knights. My first move, almost without thinking, is
Qf3, which protects c3 once and stops Nd5 for the moment. After
that, Rfc1 (a4 is weak too). Black should consider Qc6 to fight
d5 free at all costs - if you come to Ne3 too, you can think
of advancing the c-pawn to c4, followed by a5. His Nd7 stands
lousy BTW. Example variant done in my head: 1.Qf3 Qc6 2.Qxc6 Rxc6 3.Rfc1 Nd5 4.Ra3 Kg7 5.Ne3 N7f6 6.Nxd5 Nxd5 7.c4 Re8 8.Kf2 += with a comfortable endgame, but Black will fight on (especially if being an engine :-)
