Blackburne's Mate

     The last post looked at Anastasia's mate. In this one we will take a look at another mate...Blackburne's mate which involves two Bishops and a Knight against a castled King. 
     It's named after Joseph H. Blackburne, a British player who once demonstrated it in one of his games. The following game is a modern version that was played in the 1962 New Zealand Championship. 
     Ortvin Sarapu (1924-1999) was born in Narva, Estonia, learned to play at age 8 and by age 11 he could play four blindfold games simultaneously. In 1940 he won the Estonian Junior Championship, but then the Second World War disrupted his life.
     In 1943 he made his way via Finland to Sweden where he was held in captivity for the rest of the war. During a tournament at Oldenburg, Germany in 1949 he met New Zealander Robert Wade, which led to his emigration to New Zealand in 1950. Sarapu won or co-won the New Zealand Championship 20 times! 
 
 
     His opponent was Zygmunt Frankel (1921-2001) who was born in Krakow, Poland. He and his Jewish parents escaped the Holocaust by fleeing to the Soviet Union, initially in Siberia and then via the Urals and Soviet Asia. 
     In 1949 he emigrated to New Zealand and became active in administration in the New Zealand Chess scene. Frankel played in a number of New Zealand Championships and on two different occasions he was the editor of the New Zealand Chess Magazine. He passed away in Wellington after a brief illness.
A game that I liked (Fritz 17)
[Event "New Zealand Champ, Wellington"] [Site "Wellington NZL"] [Date "1962.??.??"] [Round "?"] [White "Ortvin Sarapu"] [Black "Zygmunt Frankel"] [Result "1-0"] [ECO "C44"] [Annotator "Stockfish 14.1"] [PlyCount "59"] [EventDate "1962.??.??"] {Danish Gambit Declined} 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. c3 {The Goring Gambit, a relative of the Danish Gambit. White offers to sacrifice one or two Ps in return for a lead in development, and typically follows up by putting pressure on f7 with Bc4, Qb3 and sometimes Ng5, while Nc3-d5 is another common motif.} d5 {This move, transposing into the Danish Gambit Declined, equalizes. Wild play results from accepting the gambit with 4...dxc3} 5. exd5 {This is the critical line.} Qxd5 6. cxd4 Bb4+ {A variation of the QGD Chigorin Defense is reached after 6...Bg4} 7. Nc3 Nf6 8.

Bf4 Nd8 {This is too cramping Black needed to try and complete his development by getting his c8B into play, so 13...Qd8 was his best try.} 14. d5 {An excellent move that gains space and gives his pieces access to d4. White has already established a won, or nearly won, position.} a6 {Black wants to guard against a white piece landing on b5. 14...c6 was not much better.} (14...
