Yeah, but, at least diakonia's advice doesn't put a knight on the edge... yes lots of times a move like this is best (and here I think it's good both positionally and tactically) but this gets really confusing for a player only 5 days old.
Advice like "improve your worst piece" or maybe "try to move all your pieces off their original squares" may actually be more beneficial (or even the most beneficial) even if in that specific position it's not technically the best move.
Sorry if my posts were confusing or unhelpful. Certainly feeling at a loss for how to even approach the position isn't something solved in a short time.
It's hard to know what advice is useful. Perhaps incorrectly I shy away from advice like "never do this" or "always do that" because inevitably you'll run into positions in the future where the very best move is the opposite of that advice which can be frustrating.
I do think pawn breaks are fundamental though. If they seem arbitrary or you're still not even sure what a pawn break is, that's ok. I think it's useful in any case to introduce these ideas and terms. As you continue to play and learn you'll run into these ideas again eventually, and if you've seen them before it gives you a little bit of a head start
If you only took one thing away from my post, I guess I'd want you to remember that bishops like long diagonals (that are not obstructed by friendly pawns) and rooks like half open files (again notice, at least in this case, a long line not obstructed by friendly pawns).
