📕 We have a closed center here. Based on his spatial advantage, white has started his attack on the kingside by playing c5 and attacking the base of black's pawn chain; on the other side, black is preparing for g4 to open lines and to attack the base of white pawn chain, f3.
15...h5? seems logical, but it fails as it has not recognized white's resources.
15...h5? 16.cxd6 cxd6 17.Nb5! threatening both to play Nc7 and to take a7.

15...Bd7?! is too slow. For instance, 16.Qb3 threatening both Qxb7 and c6. 16...b6 17.cxd6 cxd6 18.Nb4+/-

15...Rf7! with the idea of Bf8 and Rg7 was an amazing idea invented in 1953 most probably by Gligoric, that has become black's standard plan these days. It seems that after experiencing this position few mounths before this game with reverse colors against Trifunovic, Najdorf has decided to play it as black.

📕 After either 14...h5? 15.g5 and h4, or 14...f4? 15.h4! black will have no counterplay on the kingside.
The correct move is the aggressive move 14...b5! to blow up the center in the next few moves.

📕 16.Qg4 and 16.Qd3 are normal moves that give white slight advantage.
1.g4! is a strong move, which leads to a bind over light squares.
1.g4! h3 2.Be4 Nh4 3.0-0 g6 4.Kh1 Bg7 5.f5+/- with an eventual Nc2-b4-c6 maneuver.
