Placing the queen on f3 on the third move, without threatening mate on f7, seems to lose some of its charm in comparison to Wei Yi's game. But at least the knight is still developed on e2 without getting in front of the queen. 3... b8c6  4. g1e2  4... f8e7  5. b1c3  5... e8g8  6. d2d3  6... c6d4 [%c_effect d4;square;d4;type;Interesting;persistent;true] 7. e2d4  7... e5d4
