In the [B]20 Rf2[/B] line, Black has a resource I overlooked. It doesn't necessarily refute it or make 20 Ne4 automatically better, but needs analysis.

[QUOTE=cheesehead;366314]
[B]20 Rf2 Rc8[/B] (forced, else Black can't meet 21 Bf1)[/QUOTE][I]No, not forced after all:[/I]
[B]20 ... O-O 21 Bf1 Rfc8[/B]

If 22 Nxc4 Bxc4 23 Bxc4 Nxe5!
If now 24 Ba6 Rc6 25 Be2 Nc4 26 Bf3 Nxe3 27 Bxc6 Nxd1 28 Rxd1 Nxc6 and Black would have two pieces for his rook.
Better: 24 Bxe6 fxe6 25 dxe5 Bxe5 26 Bxh6 bxc3 27 bxc3 Bxc3 28 Nxc3 Rxc3 (or 28 R1a2 Bd4 29 Be3) and material is even. We haven't won a pawn, but Black's remaining king-side pawns are not connected, so we have that slim edge.

If 22 Bxc4 Bxc4 23 Nxc4 and we're a pawn up momentarily, but 23 ... Nd5 24 Bd2 cxb3 25 cxb3 Nxe5! 26 Nd6 Rd8 27 dxe5 Bxe5 28 Nb5 leaves us down a pawn and probably losing another.
(If 23 ... Nxd4 24 Nd6 and Black loses either the Exchange or a knight.)

Still murky. We have a few more days for analysis of whether [B]20 Rf2[/B] can force as much advantage for us as [B]20 Ne4[/B].

[B]20 Ne4[/B] remains our best move until proven otherwise.

I may not have much time for analysis in the next few days. If you don't hear from me, just post [b]20 Ne4[/b].
