Today in a speedchessmatch between Caruana and Nakamura this position was on the board:
[d]r5k1/5pp1/r1pbp3/B2q3p/1P1Pp3/P1R1P3/4QPP1/2R3K1 w - - 4 25
Caruana played here a wellknown sacrifice in humanchess 25.Tc5 !!??
Later he missed 28.Bc7!? Rxa3 29.Be5 with some chances for white. But the machine think that it is still a draw.
Maybe it is only draw but it shows that humans play the more interesting chess.
Or is a machine playing the beautiful 25.Rc5 ?

Did Caruana play the best or only the most beautiful move?
