The Fritz variant. 3. Bf1-c4 Ng8-f6 4. Nf3-g5 d7-d5 5. e4xd5 Ng6-d4
The Fritz variant is a replay of the double knight game ( 1. e2 – e4 e7 – e5 2. Ng1 – f3 Nb8 – c6 3. Bf1 – c4 Ng8 – f6 ), an opening in chess .
It arises from the Prussian game ( 4. Nf3 – g5 d7 – d5 5. e4xd5 ) after the move 5.… Nc6 – d4 and has the ECO code C57.
The German master Alexander Fritz (1857–1932) suggested Carl Schlechter 5.… Nc6 – d4, who wrote about it in 1904 in the Deutsche Schachzeitung . In 1907 Fritz wrote an article himself in the Swedish magazine Tidskrift för Schack .
White's best answer is 6. c2 – c3 . The game often continues with 6.… b7 – b5 7. Bc4 – f1 Nf6xd5 8. Ng5 – e4 or 8. h2 – h4 ( Enrico Paoli ) h7 – h6. After 8. Ng5 – e4, 8.… Nd4 – e6 leads to a minimal but permanent endgame advantage for White according to Cramer, while 8.… Qd8 – h4 obliges Black to sacrifice a piece.
These positions can also result from the Ulvestad variant 5.… b7 – b5, after 6. Bc4 – f1 Nc6 – d4 7. c2 – c3.
