Pachman Strikes Back

In the previous post, we looked at an episode between Czech grandmaster Ludek Pachman and Bobby Fischer. In revenge for Pachman's win in their head-to-head game, Fischer helped the relatively unknown Sanchez beat Pachman in a later round, sharing a bit of home preparation in an act whose ethical legitimacy was questionable at best.

The story does not end there, however, and we resume Pachman's account from Checkmate in Prague, page 65:

"With the help of Sanchez, then, Bobby had caught up with me, but the matter did not end there. Two days later, before the start of play, I was taking a walk with the young Chilean player, Jauregui. We were chatting about this and that, when suddenly on our way to the tournament hall we ran into Bobby.

"'Ah, Mr. Pachman,' he called from a distance, 'so today you've been briefing my opponent.'

"Realizing at that moment that Bobby was due to play Jauregui, I retorted: 'Of course, Bobby. And I must say he's very well prepared.'

"My prompt reply caused Bobby to frown. He pondered the first moves in the ensuing game very deeply. And as it happened, Jauregui was using a system I often play, which helped to confirm Bobby's suspicions. He spent one hour and twenty minutes over the first eleven moves, anxious not to play according to the book and so avoid the danger of surprise. In the event, he lost his queen at the twenty-ninth move and was forced to resign at the fortieth. One might almost say that a bad conscience had robbed him of a point, involving the loss of first place in the tournament."

Here's the game:

Jauregui Andrade,Carlos - Fischer,Robert James [E81]
Santiago (10), 1959

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 0-0 6.Be3 Nbd7 7.Nge2 a6 8.Qd2 c5 9.a3 Rb8 10.b4 cxd4 11.Nxd4

17...Rc7 Probably the losing move, when Black goes from a cramped and difficult, but defensible position, to one in which he's completely overrun. [17...Ba4 seems better: it (1) makes it tougher for White to pile up on the d-file, (2) makes it easier for his own rooks to cover d6, and (3) clears the better d7 square as a retreat for his knight.] 18.f4 Nc6 19.Nf3! Bc8 20.Red1 Rd7 21.b5 Nd8 22.Qb4 Re8 23.Rd2 f5 24.c5 d5 25.c6 bxc6 26.Bc5 a5 27.Qb3 Qf7 28.Ng5
