White usually protects the pawn, but this is a known gambit and the first line of the engine.

not found in my (not up-to-date) database. A problem compared to the more common 12.d3 might be to find a good role for the bishop on c1 without weakening c3 too much.

Then position is not easy to assess in practical terms and against such a strong opponent. Objectively Black is (more than) fine, but has a lot of decisions to make. Where to put the king to begin with. "If you ever find yourself confronted by a lion, avoid eye contact and stand utterly still. He will dart towards you, growling and roaring, but if you hold your nerve he is unlikely to pounce. Holding your ground against a dangerous adversary like this would be highly impressive, but it doesn't always work, and if disgruntled elephant charges in your general direction, your life depends on running away as fast as you can." Jonathan Rowson, New in Chess 1/2007 reviewing "Practical Chess Defence" by Jacob Aagaard

Probably the white queen is more dangerous on g4.
23... Rac8 and it's not easy for White to prove compensation.
24... f5
25. Bh6
The former world champion is fully back in the game.
25... g6 26. Bxf8 Rxf8?! 27. Qh3
27. Rxe6 Bxe6 28. Qxe6+ engine claims a huge advantage for White here, although no immediate tactical point is obvious. Probably the white squares and White's d pawn will decide in the long run. This is why the engine wants to take on f8 with the king at move 26.
27... e5 28. h5 g5 29. d4 e4 30. Nd2 b5?! 31. axb5 axb5 32. Nf1 Kh8 33. Ne3 Rd8 34. f3
34. Qf5 looks like a logical follow-up. Black will find it hard to defend weak pawns on d5 and b5.
34... b4 35. fxe4 bxc3 36. Bxd5 Nxd4!?
Giving up a piece to create some counterplay based on the passed pawn looks like the best practical chance, although material should matter in the end.

Allowing a comeback ...
41. Nc2 was the safe way to stop the c pawn and Black's hopes

All kind of geometrical motifs around. Black can force the draw immediately with
42... Bb4! 43. Qxb4 Rc8 Suddenly it even looks like a winning advantage for Black, as you have to give up the rook for the c pawn and saving the knight runs into mate, but ... 44. Qc5! Take care - White is still up for tricks!(44. Nh6?? Qh4+) 44... c1=Q+ 45. Rxc1 Rxc5 46. Rxc5 Qxg4 47. h6! Again the mating pattern forces perpetual - of course Black cannot take the pawn. 47...

48. Qg4! c1=Q+ 49. Rxc1 Qxc1+ 50. Kh2 White maintains the strong knight, the passed pawn and maybe some symbolic edge, but it shouldn't be enough either.

After heroic defence Laura finally stumbles, as White can now force queen exchange, which gives her king the freedom to conquer the white squares.
50... Bd6 keeps the balance.
