An interesting novelty by Tabatabaei with the idea of g4-g5.

Mohammad Amin's novelty works well and leads to a miniature win.

Parham made a blunder. The only way to put up more resistant would be:
49...Re4! 50.g3 Ne5 51.Nxe5 Qe1+ 52.Qxe1 Rxe1+ 53.Kg2 Rxe5 54.Rxd4 Rc5 +/-
White is a pawn up, but with Black's correct play, it would probably end in a draw.

20... Bxh6!
Apparently, the exchange of the dark-squared bishop weakens the black king position, but in fact White will be unable to exploit that. On the
contrary, Black can mobilize his forces to attack on the enemy king.
20... f4
Probably isn't a bad move, but this will reduce the flexibility of Black's pawn-structure. Generally speaking, Such actions are very responsible and
should be considered in all aspects. 21. Bg5 Bf6 22. Bxf6 Nxf6 23. Kh1 Kh8 24.Qe1 Qh5 25. Rf2 Rg8=/+
