E.g., a knight on one of the squares in the 4x4 space in the center has 8 moves; as the knight moves towards the edge, he has fewer moves that he can make. It is the same with the other pieces. Books with precise speech will say that what's important is to control the center, not necessarily be in the center - an important difference. Bobby Fischer is an American chess grandmaster. He is considered to be one of the greatest chess players of all time. Fischer showed his skill in early age by already winning very strong players by the age of 13. At 20 he became the US chess champion, winning with a perfect 11/11 score. Soon afterward.

<Chicago Chess Man: The best move for white was 23. Qh5! Then if PxN, 24. g6 should win.>
Yes - as was already mentioned in previous kibitzing, Fischer's 23.Bxg7+ should have led only to a draw, had Cardoso found the miracle defence 25...fxg6 26.fxg6 Rf7!! 27.gxf7 Rf8 (threatening Rxf7) 28.Qe6 Qc5+ (that's the right timing for this move) 29.R1f2 (29.Re3 Bg5; 29.Kh1 Qe5) 29...Bxf3 (29...Qe5 30.Re3) 30.Ne4! (30.Qxe7? Rxf7! 31.Qxf7 Qg5+ and mate) 30...Qe3 31.Qxe7 Qe1+ 32.Rf1 Qe3+ 33.Rf2 and draw by perpetual.
Instead, 23.Qh5!! combines pressure on the h-file and the long diagonal, creating the lethal threat of 24.g6 h6 25.Qxh6+:
23...Kg8 24.f6! Rfe8 25.fxg7 Qxf3 26.Rxf3 Bxf3 27.Qxf3 bxc3 28.h4 cxb2 29.Bxb2.
23...Qxf3 24.Rxf3 Bxf3 25.Bxg7+! Kxg7 26.Qh6+ Kh8 27.g6 fxg6 28.fxg6 Rf7 29.gxf7 bxc3 30.Qe3 threatening mate on the long diagonal as well as the two bishops.

Gee <Howard>, you really need to get yourself a computer and some good chess engines. Until then, here is what some engines have to say for both 12.c4 and Fischer's selected move 12.exd6 after 11...Nd5:

Houdini 4, d=29:

A very strange line. Why does Black sac the knight with 12...Nf4 instead of the seemingly more reasonable 12...Ndb4 like Komodo and Stockfish preferred and which Houdini itself preferred at d=28? And with 2R+N vs. Q+P it should be a win for White, even though at the end Houdini did not seem to know how to proceed.
2. [+0.54]: 12.exd6 Bxd6 13.Ne4 Ba6 (here Sherwin deviated with 13...c4) 14.Nxd6 Qxd6 15.dxc5 Qxc5 16.Bd2 Rbc8 17.b4 Qe7 18.Qb3 Bb7 19.a3 Nf6 20.c4 Rfd8 21.Bc3 Nb8 22.Rad1 h6 23.Rxd8+ Rxd8 24.Rd1 Nbd7 25.Qc2 Be4 26.Qe2 Rc8 27.Nh4 Bxg2 28.Kxg2 e5 29.Nf5 Qe6 30.Nd6 Rc6 31.Qd2 e4 32.b5 Rc5 33.Qe2 Rg5 34.Kg1 Rc5 35.h3

White has the B vs. N advantage and a q-side pawn majority even though his c-pawn is currently backwards. But the octopus knight on d6 is strong and can be reinforced by Bb4. So I think that Houdini's evaluation of White's position is more pessimistic than it really is.

Komodo 8, d=27:
1. [+2.13]: 12.c4 Ndb4 13.exd6 Bxd6 14.Ne4 cxd4 15.Nxd6 Qxd6 16.Bf4 Qe7 17.a3 Na6 18.Nxd4 Nxd4 19.Bxb8 Nf5 20.Be5 Bb7 21.Bxb7 Qxb7 22.b4 Nb8 23.Qd3 Nd7 24.Bb2 Rc8 25.Rad1 Nf8 26.Rc1 Nd7 27.Qe4 Qc7 28.Red1 h6 29.Rd2 a5 30.Bc3 h5 31.f3 a4 32.Qc2

After displacing the knight with 12.c4, it's 16.Bf4 which gives White the material advantage. 23.Bxb8 Qxb8 24.Qc2 reducing material further and planning to occupy the d-file with 25.Rad1 and advance the q-side pawn majority was also a possibility (24...Nd4, 25.Qc3). In the final position White's q-side pawn majority and upcoming control of the d-file probably gives White a winning advantage.
