I have Purdy's Book, Reshevsky' s and Glirgorich.
Although at one time I had all the others.
Purdys reads the best, then Gligorich and then the cold Reshevsky.
With Purdy I have found he is either spot on and dead right or
shoots off an a very interesting and thought provoking angle.
Think this may be the game Robbie is mentioning.
Some light notes based on Purdy's comments.
In particular the bit about 2 pawns hold back 3.
I never thought of that when I looked more deeply at the game,
suppose because I knew an ending was never going to happen. 😉
Pity in a way that Spassky missed 27...Bxa4 it
was shaping up to be a classic.
B.Spassky - R.Fischer. Game 5 1972. 'The Rebel Within'
Fischer knew when to break the rules.
1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Nf3 c5 5. e3 Nc6 6. Bd3 Bxc3+ {Gives the opponent the two Bishops with this unprovoked exchange.} 7. bxc3 d6 8. e4 e5 9. d5 Ne7 10. Nh4 h6 11. f4 Ng6 {A move many a strong player would shy away on principle. See the next note to what two 'rules' this breaks.} 12. Nxg6 fxg6 13. fxe5 dxe5 {White has been given a protected passed pawn and the two White Kingside pawns are holding back the three Black Kingside pawns. All this is now opening theory. On the 20th of July 1972 Fischer was writing it.} 14. Be3 b6 15. O-O O-O 16. a4 a5 {Black has just created a backward pawn on an open file. Fischer has tore up the books Reinfeld wrote.} 17. Rb1 Bd7 18. Rb2 Rb8 19. Rbf2 Qe7 20. Bc2 g5 21. Bd2 Qe8 22. Be1 Qg6 23.Qd3 Nh5 24. Rxf8+ Rxf8 25. Rxf8+ Kxf8 26. Bd1 Nf4 {Now the best move is 27.Qb1. Fischer then marches his King to the queenside to hold the b-pawn freeing the Queen. It would have been so instructive to see how Fischer would have continued from here.} 27. Qc2 Bxa4 {Fischer very very rarely missed a shot OTB. A deadly tactician. Spassky resigned here. One line is....} 28. Qxa4 Qxe4 29. Kf2 Nd3+ 30. Kg3 Qh4+ 31. Kf3 Qf4+ 32. Ke2 Nc1
