Today Wesley So accepted the drawoffer by Ding Liren in the semifinals of the World-CUP 2017.
But was he really right to accept this drawoffer?
Did Houdini 6 see a win for So ?

Interesting position.
41.Rxb3! wins, but I guess that a lot of engines will find that move.

Re: Did Houdini 6 see a win for So ?
It´s right that the chessprograms give 41.Rxb3 a winning score. But the lines they show didn´t end in a clear winning position.
Wesley So says in an interview that he thinks that black has sufficient counterplay after 41.Rxb3 !
See the interview after 4h 9 minutes:

I hope to see a line by an engine that is a real convincing win for white.

It's a clear win after 41.Rxb3 axb3 42.gxf6 gxf6 43.Rg8+ Kd7 44.Nb4 Ke7 45.Rc8
[D]2R5/2p1k3/1p1p1p2/rP2pP2/1NP1P3/1p1P3r/1P1K4/8 b - - 5 45
The main line continues 45...Ra2 46.Nxa2 Kd7 47.Ra8 bxa2 48.Rxa2 Rh2+ 49.Kc3 Rh1 50.Ra8 Rc1+ 51.Kd2 Rg1 52.Kc2 Rg7 53.Kc3
[D]R7/2pk2r1/1p1p1p2/1P2pP2/2P1P3/2KP4/1P6/8 b - - 10 53
and this position is over +5 for White.

I analyzed the position with SF over night. If anyone is intrested here is the engine output thus far. (+5.61 for white)Thomas Lagershausen wrote:[D]2k5/2p3p1/1p1p1p2/rP1NpPP1/p1P1P3/Rn1P3r/1P1K4/6R1 w - - 3 41

In the highlighted move above, it was pointed out in
some articles Kd7 Rxc7+! wins faster. Not sure if their analysis is correct.

I followed a slightly different line, and restarted at some point. Just starting from plydepth zero can help restructuring the tree (because IID is not very good at this.) This was done twice. From this line

I then got finally after ten hours or so a FH resolved, at plydepth 70
(just in)(Search starts already with a high 6.96 because hash was still there. Main thing to take away from this for me is that it really takes very long to convert the high eval to an even higher one. It probably would have helped if after a few hours I 'ramped' the search, IID, up again, to borrow a term from the Large Hadron Collider guys in Switzerland

Search is default Stock 2017-08-20. I think this was Uri's version that knows about real Bishop pairs.

I followed a slightly different line, and restarted at some point. Just starting from plydepth zero can help restructuring the tree (because IID is not very good at this.) This was done twice. From this line

I then got finally after ten hours or so a FH resolved, at plydepth 70
(just in)(Search starts already with a high 6.96 because hash was still there. Main thing to take away from this for me is that it really takes very long to convert the high eval to an even higher one. It probably would have helped if after a few hours I 'ramped' the search, IID, up again, to borrow a term from the Large Hadron Collider guys in Switzerland
