Η συνέχεια που θα ασχοληθούμε εδώ είναι η 1. d4 Nf6 2. c4 c5 3. d5 e6 4. Nc3 exd5 5. cxd5 d6 6. Bf4 g6 7. Nf3 Bg7 8. e4 0-0 9. Nd2. Ο λευκός ετοιμάζει την μεταφορά του ίππου στο γ4 πριν ολοκληρώσει τη ανάπτυξη του στοχεύοντας να κυριαρχήσει πιέζοντας το δ6 και δυσκολεύοντας την ανάπτυξη του μαύρου.

Στο άρθρο αυτό θα δούμε τρεις απαντήσεις. Και οι τρεις στοχεύουν στο γρήγορο άνοιγμα του κέντρου με f7-f5 , με τον λευκό βασιλιά στο κέντρο και τον αξιωματικό στο ζ4 να αποτελεί τέμπο.
