Should I continue developing or start the attack?

As White, it’s my move, and I’m unsure how to approach this position. I know I have a better position and should focus on pressing the kingside.

However, my entire queenside is still undeveloped. I’m considering either developing my bishop to activate that piece or pushing my f-pawn to gain tempo. At the same time, I’ve heard it’s best to complete development before launching an attack.

How should I approach these situations?

It's really about the specifics of each position...here I think f4 must be correct. You drive the Knight to f7, you continue f5 blasting it open, the black king is super bad, the Rh8 is a stupid piece, black has no counterplay etc etc all things point to it being justified to directly attack vs continue developing as you can cause severe issues for black if you do. If you play more slowly and develop you are probably still quite a bit better because of the poor black position, but eg. Bf4 does not really achieve very much other than simply getting this bishop out.

knight has a good outpost but its not enough for checkmate and doesnt pose any serious threat atm. black can easily force trade that knight and you have also lost your white bishop which is one of the main attacker. keep developing while also defending the supporting pawn and add more attackers. you should get the bishop out first then the knight and then bring rook to the open file adding pressure to the black knight. if you are able to trade your bishop with their bishop then you have checkmate but for that the q has to be bhind the bishop. first move B to F4 then Q to D2 then trade it off and then Q G7 is check mate because their Q is blocked. the board always changed so you have to keep an open mind. goodluck btw i may be wrong im just a noob.

I was considering playing f4, but after chasing away the knight (or if it retreats to Ne5 after f5), I couldn't identify any significant threats, even with the king exposed, as I don't have any major pieces positioned to launch an attack. The main difficulty in deciding between f4 and continuing development was the possibility that, despite exposing the opponent's king, the lack of immediate attackers might give them enough time to bring more defenders to the kingside.

I never thought about trading the bishops, as keeping them on the same color makes it easier to attack the king. Thank you for the advice!

You say the choices are to develop or to attack.

Why not develop and attack? The move f4 and f5 to follow develops the rook at f1. Once the f-file is opened, you will be able to develop the Bishop at c1 while attacking and eventually swing the Rook at a1 to the kingside.

As has been said before, every position is different. But it is almost always good to develop with tempo.

You should always try to do both at once, especially if your opponent is the one attacking you. Make moves that they can't ignore without facing dire consequences.

I would play f4 - not because I like the idea of attacking while incompletely developed, but because you don't appear to HAVE a good developing move.

What would be the point of "developing" the Bishop? On what square would it be more relevant than it already is, sitting on c1?

Wait!

What about a4?

Threatening a5, which drives the Black Knight away and removes the pressure on your d5 Pawn thereby preparing to move your Queen into the attack... and a4-a5 also prepares Ra4!

How about 1. f4 Nf7 2. a4?

f4 Nf7 f5 looks best. If the knight goes anywhere else it gets trapped or forced to the edge. If they take you just recapture and mate the king. Attacking, you use pawns, space, and pieces, but most important is time. Computers playing attacking chess will sacrifice pieces for a single move. If we play f4 and f5 we make our opponent commit. If he ignores f5, I don't know though. If takes, he might have enough time to put the rook on h7, bishop to g7 and the knight on d8.

If he ignores your f5 move, play a4-a5 and Ra4 to swing it across to the K-side!
