Ludek Pachman's Book, Attack and Defense in Modern Chess Tactics, Page 97, game
of Ravinsky vs Panov, 1947.

Can any program see White's move?

1)P-K4 P-QB4
2)N-KB3 P-K3
3)P-Q4 PxP
4)NxP N-KB3
5)N-QB3 P-Q3
6)P-KN3 N-B3
7)B-N2 B-Q2
8)O-O P-QR3
9)B-K3 R-B1
10)Q-K2 P-QN4
11)P-QR3 N-K4 (Pachman gives this a "?", B-K2 was in order)
12)QR-Q1 N-B5
13)B-B1 NxRP (Again, Pachman gives this a "?"; he suggests B-K2 instead)
14)P-K5! PxP
15)N-B6 Q-B2
16)NxKP N-B5 (Pachman says the pawn grab cost Black two tempi, and now he wil
pay for them)
17)NxB NxN
18)N-Q5 Q-R2 (...W-K4 is more natural, so says Pachman)
19)N-B4! QN-K4?
20)RxN!! ("The prelude to a beautiful combination.  By sacrificing a Rook White
destroys the Black King's pawn cover and obtains an irresistable attack down the
open K-File")
20)...NxR
21)NxP! PxN
22)QxP ch B-K2
23)R-K1 Q-B4
24)P-QN4! N-B1?
25)Q-N4! Q-B6
26)RxB!!! and white soon won...
