If that is the correct game score, then Adams resigned in a possibly winning
(and certainly better) position:
38.Rg1 Nb5?
[38...Bf8! 39.Nf5 Ne6 40.Bxe6 fxe6 41.Nd4 Bxb4 +=]
[38...Bxb4 39.Qf4 Rg7
(39...Qa7 40.Rg5 (40.Nf5 Bf8 =) 40...Qc5 41.Bf5 Rg7 42.e6 +-)
(39...Qa5 40.Rg5 Rg7 (40...Rbd8 41.Rbg1 and White mates) 41.Nc2 +-)
40.Nf5! gxf5 41.Bxf5+ Kg8 42.Qh6 Ne6 43.Rxb4 Qxb4 44.c7 Re8 45.Qh7+ Kf8
46.Qh8+ Ke7 47.Qxe8+ Kxe8 48.c8Q+ +-]
39.Nf5 gxf5 40.Bxf5+ Rg6 41.Qxd5 Rf8 42.e6?
[42.Qe4 Rfg8 43.e6 Nd6 44.exf7 Nxe4 45.fxg8Q+ Kxg8 46.Rxg6+ Kf7 47.Bxe4 +-]
42...Nd6
[or 42...Kh6 =]
43.exf7? {Black resigns??} Nxf5 44.Qxf5 Qxc6 45.b5 Qe6 -/+
