White's miscalculation. When your pieces are hanging, grabbing a pawn is not logical.

📘 In this position, Black could have forced a draw by 49...Ra1+ 50.Ke2 Ra2+, but Parham is smart enough to try his only winning chance.

Fine prophylaxis. The immediate point is to reconfirm the role of b3 in supporting c4, but there is a deeper point about the unfortunate placement of Black's minor pieces on the b-file. 17...c6 18.c4 Qc7 19.Bd3+/-.

📘 18...Ra7!
An excellent idea. If 18...Rfc8, White could triple on the c-file: 18...Rfc8? 19.Rc1 Rxc6 20.Qxc6 Qxc6 Nxc6+/-.
