How to protect f2/f7 pawns

I just watched the chess.com lesson called Weak Targets: f2 and f7 and realized something crazy:

So how can I protect my weak pawn from getting attacked? (I know that castling early is helpful, but is there anything else?

Develop your pieces and don't block in your bishops. 2.d6?! failed to follow both of these rules. Other than castling it is the best option because more pieces on the board will equal more possible defenders of the sqaures.

move horse to the side of the board

Also placing a piece to defend the e-file would support bishop e6 if he tries to fried-liver you

2... d6 is not a bad move at all, in fact it has been played 9,000 times in master games, and is welly respected.

it is not a horse

J obvously a 1300 knows that. It's just a joke.

Anyone who knows how to play the Philidor wouldn't play bg4 or a6 if the bishop was already played out to c4. After bc4 just nf6, be7 and 0-0, and black's position is extremely solid.

generally Black's middlegame plans are to expand on the queenside, playing bb7 or ba6 depending on move orders.

Also let it be known that playing bc4 in the Philidor isn't the critical way to play it as white. Playing d4, immediately striking in the center is preferred.

Philidor is a sound opening

This is what happens if they try to attack you fried liver style

Black is down a pawn after d5 but he's better

Usually by either sacrificing material or simply not letting the rnemy pieces go to squares that attack f7

My bad it is an opening. Sorry peeps

I am dumb
