Playing in the centre with 18.Rad1 also looks good, retaining the possibility of transferring the rook to the queenside via d4.
Going into an endgame allows Black to prolong his resistance.
A more convincing way to win was 22.Qf3 Rb8 23.Rxb8+ Nxb8 24.Re4, with a decisive attack.

Now we reach a technical position, with extra material for Black, but even in the case of 20.Kxb2 Ba3+ 21.Kxa3 Qc3+ 22.Nb3 a4 23.Ba7 axb3, White cannot avoid a quick mate.

On 16.Re1, the knight returns with 16...Ng4, and there is a threat of ...Qe7-g5-h5.
