Such a good question. I have Silman's HTRYC book too and found it much of it confusing and difficult. However in your position in the first board, could a plan possibly be to clear the c-file, as your rook is on the same file as Black's queen? 1.Ne5 Nxe5, 2.dxe5 starts to clear the d-file, also attacks black's knight on f6, a main guard of his king.
What else is there - as you say, the QS pawns are protected and doing a good job, but pushing the KS pawns weakens your king...
I've been reading Jeremy Silman's book How to Reassess your chess. I know there exists imbalances and you should do something with them. The thing is when I'm able to identify the imbalance I don't know what to do with it. I know there is an imbalance but now what do I do?
For example
That would be my breakdown, pretty superficial but is the best I can come up with. Now that I know the main imbalance is the hanging pawns, what do I do? What now? They are defendend, black can't play e5. I don't see anyway that black can put any more pressure on my pawns. How do I do take advantage of this? A pawn push would create too many weaknesses on my camp, there seems to be nothing for me.
I don't know what should I be going for here. The placement of my pieces don't look terrible and I'm trying to avoid mindless moves such as Ba1, it is not bad but there is no plan behind it. Black seems to have no weaknesses and I don't see any clear path to creating one.
But when I think I have found one, it seems that all my moves to complete it were bad. This is a game I played with white, I tried to take advantage of black's doubled pawns
