Taking Turns Blundering

     The expected winner of the 1948-49 New Zealand Championship was Tom Lepviikmann (1900-1968) who was originally from Estonia, but for many years he lived in The Netherlands before finally settling in New Zealand in 1939. He won the New Zealand Championship twice in 1945/46 and 1946/47. However, for this year’s event he was in very bad form and only on a couple of occasions did he show what he could do. 
     Instead, the winner was Alan Nield who played aggressive, but steady chess. The runner up was David Lynch (1910-2002) who was New Zealand North Island Champion in 1949 and won the New Zealand Championship in 1951. He was also New Zealand Correspondence Champion on three occasions in the 1940's and 1950's. In the 1952 New Zealand Championship he was the player who stopped Ortvin Sarapu from getting a perfect 11-0 when they drew in the last round. 
 
 
     The other favorite was Harold McNabb (1914-1988). In 1934 he spent two years in hospital with an injured spine and during this time studied chess seriously, with the aid of a special board crafted by his brother. 
     He was a strong player, finishing runner-up in the New Zealand Championship at least four times as well as winning numerous other event. He also he played for New Zealand in numerous international team matches. 
     McNabbe lived in Wellington for a period during the 1940s before returning to his place of birth, Nelson, a city on the northern tip of South Island. 
     Robert Wade, an IM originally from New Zealand, wrote that personally he feared McNabb’s play more than anyone else in New Zealand except perhaps twice New Zealand Champion Philipp Allerhand. Wade said that if you gave McNabb “an edge...there will be no more chances.” 
     Although MeNabb played some good games in this championship he was not at his best and failed to win some games that would ordinarily have been easy for him. His game against Nield, is a good example...he should have won, but after trading mistakes the point went to Nield.
     Alan E. Nield (March 4, 1893 – April 2, 1972) also won the 1950 BCF Major Open tournament in Buxton, England with a +9 -1 =2 score. In their game Nield’s courage in playing a tricky line in the Ruy Lopez was matched only by his incredible luck. The game proves that Tartakower was right when he said the game is won by the player making the next to last mistake.

  A game that I liked (Fritz 17)

[Event "New Zealand Champ.

In the Open variation black tries to make use of the time white will take to regain the pawn to gain a foothold in the center.} 6. d4 {The universal reply.} b5 7. d5 {A surprising move that was likely a prepared variation, but it's known not to be very good. The only good move here is 6.Bb3} Ne7 {When this game appeared in print the annotator mistakenly called it an error and, also, Modern Chess Opening (the opening Bible of the day and for many years to come!) also claimed that the correct move is 7...bxa4. That's wrong! McNabb's move is the correct one and the auto-annotation by Stockfish awards it a "!"} (7... bxa4 8. dxc6 {[%emt 0: 00:00]} d6 (8... dxc6 9. Qxd8+ Kxd8 10. Nxe5 {is good for white.}) 9.

Whute now has what should be a decisive advantage.} bxa4 {What else? } 10. d6 {A decisive punch!} a5 {There really wasn't anything better.} (10... Bb7 11. Nc3 cxd6 12. Nc4 Qc7 13.

However, the games were long, difficult endings and there is no guarantee that the two players would play up to the engine's standards!]}) 23. Nd4 {The N attacks the R, d6 is attacked 3 times and the N on d7 is undefended...it looks grim for black, but in theory the chances are equal.

The person annotating the game that I saw claimed that white had "no intention of giving up his Knight for a mere Rook." Both Nield and the annotator were mistaken, but they did not have Stockfish and plenty of time to fiddle around with the position!} (25... Rfc8 26.
