{By all accounts, William Lombardy was complicated. Most people are more
familiar with the name than the man, and many have gained their insights from
the character portrayed by actor Peter Sarsgaard in the 2014 film Pawn
Sacrifice. I had only ever exchanged a handful of words with GM Lombardy,
though I long ago learned of his many achievements. If a perfect 11-0 at the
1957 World Junior wasn't enough, the fact that he served as Bobby Fischer's
second made him a legend. Not all of his moves will stand the test of time,
but there was no denying Lombardy's energetic play.} 1. c4 Nf6 2. Nc3 e6 3. Nf3

hand White a protected passed pawn that further restricts Black's pieces. But
passive shuffling only provides White the required time to regroup his pieces

easily blockaded.} 19. c5 b6 20. Rab1 ({Attempting to centralize the knight
