A variation of this sequence with the Elephant Trap is named after an event at Cambridge Springs. Siegbert Tarrasch developed a response to this sequence, (15[1])whose main line (15[1]-5[1])leads to semi-open c- and (-5[1])e-files. (-5[1])Adolf (-5[1])Albin names a sharp “counter” (15[1])to this sequence (15[1]-5[1])that he used against (15[2]-5[1])Emanuel Lasker. (15[1])In (-5[1])1927, Alexander (-5[1])Alekhine and Jose Raul (-5[1])Capablanca (15[1]-5[1])began over 30 games (15[1])in a row with (-5[1])this sequence’s (-5[1])(*) “declined” (10[1]-5[2])version. (10[6]-5[1])Bobby (10[6])Fischer (10[1]-5[1])avoided (10[3]-5[2])playing (10[3])[emphasize] (-5[1])against this opening with an Indian Defense, instead of moving a central (10[1])piece. Despite its (10[2])name, if this sequence is “accepted,” the (10[2])sacrificed (10[4])material is only a temporary (10[2])loss. This (10[2])opening (10[1])begins with the (10[1])moves d4, d5, and (10[1])c4. For 10 points, name this (10[1])common chess opening for (10[1])white, which also names a (10[1])2020 (10[2])Netflix (10[3])miniseries (10[2])starring Anya Taylor-Joy. (10[7])■END■
