Mistakes Were Made

     Margate 1939 was the last of five consecutive international tournaments organized at the seaside resort of Margate, England because the outbreak of World War II put an end to them. 
     The 1937 event brought together ten masters, including Capablanca who was set to play, but a few days before the start of the tournament it was announced that he was being replaced by Alekhine. 
     Capablanca's withdrawal was officially due to "diplomatic duties." However, it has been speculated that it may have been due to health issues. In a January 1937 letter from Havana he had requested a leave of absence from his diplomatic work in Europe due to medical treatment that prohibited his traveling. But, that appears to have been hogwash. 
     On March 29, 1937, two days before Margate commenced, Capablanca was well enough to travel to Miami to play a simultaneous, kick off a local tournament, be back in Havana on April 1st and on April 17th conduct a 70-board consultation simultaneous. 
     At Margate Reuben Fine and Paul Keres shared first place, both having gone undefeated while Alekhine displayed his usual aggressive style by not taking any draws. He only managed third place though because of losses to Fine and Keres and, surprisingly, to Victor Berger. A fitting end to the tournament came in the final round when the two leaders met and battled to a standstill. 

     Victor Burger (or Buerger) , a Ukrainian–British player, was born in January, 1904 in Mykolaiv, Ukraine and was a member of the London Chess. He died in London in 1996. 
     He played with varying success in tournaments in the mid-1920s to early 1930s. His main claim to fame was his defeat of Alekhine in this tournament. The game was somewhat marred by multiple time pressure mistakes by both players. Burger especially only had a few seconds for his remaining moves before the time control. 
     I have not seen any annotations to this game, but have read comments quoted from various sources about the mutual double blunder: Alekhine's 36...Qf4 and Burger's 37.Nxe4, both of which have been given double question marks.
     However, looking at the game with Stockfish 15 and Komodo 14, it's clear that Alekhine was dead lost no matter what he played and the difference between Stockfish's recommended 36...Qg6 and the move played by Alekhine was about 1.5 Ps, but that margin was not enough to make any difference! 
     After Alekhine's move, Burger had a huge advantage and his move dropped the evaluation drastically, but even so, he had a winning position anyway. A game that I liked (Komodo 14)

In this position black does not have anything that can be considered better! Stockfish 15's evaluation of this position is about 10 Ps in white's favor. Komodo 14's evaluation is a bit more conservative at 6.75 Ps.} (36... Qg6 37. Rxe4 {leaves black a piece down with no compensation and Komodo 14's evaluation is that he is about 4.5 Ps behind.}) 37.
