The Other Christmas Tournament

     Everybody knows about the annual Hastings Christmas tournament. The first one took place in 1920-21 and was a four player double round-robin of British Champions, won by Frederick Yates ahead of R.H.V. Scott, Henry Atkins and Richard Griffith. It grew in importance and the winner's list became a Who's Who of chess champions. 
     There was another international Christmas tournament in Lucerne, Switzerland, but it only lasted from 1947-48 to 1953-54 and the most prominent winner was former World Champion Max Euwe in 1950-51 who tied with Herman Pilnik of Argentina. 
     Just three weeks before, in the 1950 Amsterdam tournament, Euwe and Pilnik met in round 7; Pilnik won and they ended up sharing sixth place. There were 18 players and Najdorf finished ahead of Reshevsky. 

     At Lucerne they met in the last round, played 25 moves and called it a draw. In the following game, in a good position, the Swiss Master Martin Christoffel strives for more than he should have and his plans were frustrated by two counters by Pilnik...one on the Q-side, the other on the K-side. Black was then left with the better ending and managed to win against demoralized resistance. A game that I liked (Komodo 14)
[Event "Lucerne"] [Site "?"] [Date "1950.??.??"] [Round "?"] [White "Dr. Martin Christoffel"] [Black "Herman Pilnik"] [Result "0-1"] [ECO "B91"] [Annotator "Stockfish 15"] [PlyCount "92"] [EventDate "1950.??.??"] {Sicilian Najdorf} 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. g3 { This is known as either the Fianchetto Variation or the Zagreb Variation. Despite its quiet appearance black has to play accurately. Spanish GM Javier Moreno Carnero explains, "...in general, theoreticians have not investigated this line deeply enough, probably because they consider it a minor line, and as result underestimate its real value. Many Najdorf specialists have experienced some problems due to this, mainly because they did not really know the dangers hidden in this scheme. This variation is not only strategically complex, but also a bit of transpositional chaos because many lines can be reached through different move orders."} Bg4 {Very seldom played. Black almost always replies with 6...e5} 7. f3 Bd7 8. Bg2 {White continues in a slow, but solid, way. More aggressive is 8. g4, the loss of time being insignificant because clack has also lost time with his B. The initiative is what is important here.} (8. g4 h6 9. Be3 e6 10.

Qe2 Rc6 {By transposition the position has reached one very similar to the Boleslavsky Variation. where the entire game centers around one single strategic goal: the control of d5. It's complicated...opposite flank attacks often happen as do breaks in the center and tactics can erupt. So far white has played well and holds a a slight advantage. He ought to now continue with 17.Nd5.} 17. h3 { Christoffel wants to continue with 18.f4 so first guards first against 18...

In many cases annotations were based on the result and they were also quite superficial. Hans Kmoch gave this move a ! and called it the finishing touch. In fact, it's question mark worthy because it should have allowed white to equalize. Of course, Kmoch didn't have Stockfish.} (37... Be5 {is winning.} 38. Re7 Ng5 39. Kh1 (39. Rxe5 Nf3+) 39...
