Romantic stuff

Το Γκαμπί του βασιλιά από πολλούς θεωρείται ένα δευτερεύον άνοιγμα, αφού ο Λευκός μένει αρκετά εκτεθειμένος με την προώθηση του πιονιού στο ζ4. Ωστόσο παράγει θέσεις ενδιαφέρουσες με πολλά τακτικά στοιχεία. Ιδανικό για ένα ματς μεταξύ μηχανών. Ας δούμε πώς το Leela χειρίζεται το Γκαμπί του βασιλιά εναντίον του Stockfish.
