Beautiful combination from Paul Morphy vs Eugene Rousseau, New Orleans, 1849. White to move and win.

23...Bxg2!
Mamedyarov finds the best continuation.

26.Nc5! Re8 27.Ne4 Rf5 28.Rad1 Bf4 29.Qh3 Rh5 30.Qf3 Bxd2 31.Rxd2 Qh6 +/-
White is still better but his task is not easy.
26...Rg5 27.Ke2?
Aronian's miscalculation. He has neglected the opponent's reply.
27. Nc3!
A) 27...Bf4 28.Qe7 Rg1+ 29.Ke2 Rxe1+ 30.Kxe1 Qg1+ 31.Ke2 Qg4+ 32.Ke1 Qg1+ with perpetual check.

40.Nxd5??
The Estonian grandmaster thought that Black was not able to play 40...Re2 on account of 41.Nf6, and creating an inescapable mating net, but...
40...Re2! 41.Nf6 Rxh2 42.Kd1
Now he understands that 42.Rb8 is followed by 42...Rc2+! 43.Kd1 Rc8 -+ but it's too late.
42...Rc2 43.Rb4 Rc8 0-1
