12...a5 13.Nd5
The mainline in Mega24 runs 13.b3 Nd7!? 14.Be3!? Nc5 15.Rab1 Qb6!? 16.Rfc1 Rfc8, reaching a position that appears 875 times, slightly favouring White, according to Stockfish17 and Dragon1.
13...Nd7!? 14.Rac1!?
Placing a rook on a file that will probably become open if Black captures on d5, either willingly or because of White pressure. The commonest continuation in Mega24 is 14.Bxg7, although frequently in such Maróczy Bind positions Whites keep their better bishop on the board by retreating it to e3 or f2.
14...Bxd4+!? 15.Qxd4 e5!?
Gaining central space. Black hopes to mask the backward d pawn by manoeuvring the knight to d4.
16.Qd2
The engines suggest 16.Qe3, but 16...Bxd5 17.cxd5 Nc5 looks fine for Black.
16...Nc5 17.Rfd1 Ne6 18.Qe3 Bxd5

19.Rxd5?
At first glance this may seem promising, but it allows Black a winning attack. Instead 19.cxd5 Nd4 gives a position in which Black's better minor-piece slightly outweighs White's central space advantage, according to the engines.
19...Nf4
This wins material.
20.Rd2
The engines prefer giving up the exchange with 20.Rd3!?
20...Qg5
As well as mate at g2, Black threatens to win the white queen with 21...Nh3+ etc.
21.Kf1 Qxg2+ 22.Ke1 Qxh2 23.Bf1 Qh4+ 24.Kd1 Qe7 25.Rh2 Kg7 26.Kc2 h5 27.Kb1 Rac8 28.Rd1 Qc7 29.Rhd2 Rfd8 30.Qa3

| Black cannot save the d pawn, but exchanges on d6 will let Black successfully activate the passed h pawn |

30...h5 31.Rxd6!?
This hastens the end, but if Black is allowed to remain two pawns up White loses anyway.
31...Rxd6 32.Rxd6 h3 33.Rd2 Rd8 34.Qc3 h2! 35.Rxh2 Rd1+ 36.Kc2 Rxf1 (0-1, 45 moves)
