Crouching Tiger
Dr. Anthony Saidy - Robert Fischer
New York ch-US, 1964
Without pawns on d4 and d5, White would even have a slightly better endgame. In this situation, Bishop is limited with its own pawn and one of White pieces will be tied for defence. Knight, on the other hand, can jump over the barriers. No one can claim for certain if Black is winning or position is a draw, but White is condemned to long, passive defence.
1…Nf8
White King can quickly reach the center, but then what? 
It can’t go any further or get involved in active operation, and Black can take his time to improve the Knight first. Ne6 will have an eye on d4 pawn, thus keeping one of the White pieces in passive position, and support future advance on the kingside.
2. Ke2 Ne6 3. Kd3 h5!
Now it’s time to bring the King to a better square. King on d6, except looking pretty, does nothing, its real destination is f5. Kf8-e7-f6-f5 takes four moves, and so does h5-Kh7-g6-f5. White has only one weakness, pawn on d4, and in order to achieve success, Black has to advance kingside pawns and create another target. Therefore, it is better to start King walk with 3…h5.
Please note how aggressive is Black in the initial endgame phase. This attitude influences Saidy to accept the defencive mode and prepare to ‘hold tight’.
4. Be3 Kh7 5. f3 Kg6 6. a4 Kf5 7. Ke2 g5 8. Kf2 Nd8!?
Fischer has reached the optimal pieces’ setup, but now he is suddenly slowing the pace instead of taking action. Saidy is still in ‘hold tight’ mind set and Fischer is taking steps to ‘put his opponent on sleep’. Both players will be maneuvering around for the next 10 moves and White will be careful not to create any new weaknesses. But this lullaby will deceive his alertness and there is bigger chance that he won’t react accordingly at the crucial moment.
This is a powerful psychological weapon that is particularly distinguished with the modern speeding of time controls.
9. Bd2 Kg6 10. Ke3 Ne6 11. Kd3 Kf5 12. Be3 f6
This pawn will go to f4, but Fischer makes it looking lazy.
13. Ke2 Kg6 14. Kd3 f5 15. Ke2 f4 16. Bf2 Ng7 17. h3 Nf5 18. Kd3 g4!
Suddenly Fischer is breaching on the kingside, even if temporary sacrificing a pawn.
19. hxg4 hxg4 20. fxg4
White has to take, otherwise Black has devastating g3 and wins one of the pawns.
20…Nh6 21. Be1?
And Saidy is still sleeping…This was the only time to try with active counterplay but changing the predominant mind set is incredibly hard. 21. Bh4 Nxg4 22. Bd8!? (with idea a4-a5) Ne3 23. g3!? Nc4 24. gxf4 Nxb2+ 25. Kc2 Nxa4 26. Kb3 (Black won himself a pawn, but Knight is too clumsy on the edge and White King will break through) b5 27. Kb4 a6 28. Ka5 with wonderful chances for a draw.
21…Nxg4 22. Bd2 Kf5
Now White is lost because Black King is storming towards g2 pawn. Fischer’s psychological warfare paid off.
23. Be1 Nf6 24. Bh4 Ne4
25. Be1
It is too late for 25. Bd8 because White King will be tied for g2 and there is no sufficient activity on the queenside.
25…Kg4 26. Ke2 Ng3+ 27. Kd3
Unfortunately for White, pawn endgame is lost. Having good ‘higher level endgame’ is always adding to your advantage, see also Uhlmann-Lukin and Popovic-Razuvaev. 27. Bxg3 Kxg3 28. Kf1 f3 is winning for Black, while 27. Kf2 Kf5 28. Kf3 Ne4! 29. Bh4 Nd2+ 30. Ke2 Nc4 31. b3 Na5 32. b4 Nc6 wins a pawn.
27…Nf5 28. Bf2 Nh4
29. a5
Once again trade is out of question.
29…Nxg2 30. Kc3 Kf3 31. Bg1 Ke2 32. Bh2 f3 33. Bg3 Ne3! and White resigned because there is no defence of Nf5. 0-1
