1. c2c4  1... e7e5  2. b1c3  2... g8f6  3. g1f3  3... e5e4 [%c_effect e4;square;e4;type;Interesting;persistent;true] A very interesting gambit that is popular among the chess elite these days. 4. f3g5  4... c7c6 [%c_effect c6;square;c6;type;GreatFind;persistent;true] 5. g5e4  5... f6e4  6. c3e4  6... d7d5  7. c4d5  7... c6d5  8. e4g3  8... h7h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] This is one of the ideas: the knight is chased. 9. e2e3 Necessary to release the e2-square for the knight. 9... h5h4  10. f1b5 [%c_effect b5;square;b5;type;Inaccuracy;persistent;true] Krush was probably surprised in the opening, and now she makes a natural move, developing the bishop before putting the knight on e2. This move, however, is imprecise: the bishop needs to help the white king. 10... b8c6  11. g3e2  11... f8d6 [%c_effect d6;square;d6;type;Inaccuracy;persistent;true] A natural development move but a little slow for what the position asks for. 12. e1g1  12... d8f6  13. f2f3 [%c_effect f3;square;f3;type;GreatFind;persistent;true] An important move, as the f3-square is a weakness that needs to be protected. The best is to place a pawn there. 13... c8d7 Perhaps it would be better to place the bishop on a more active square. In order to achieve this, it's necessary to speed up the Bc7-Qd6 plan. 14. d2d4  14... e8c8  15. c1d2  15... d6c7  16. b5d3 A useful move, sooner or later. The bishop gives way to White's plan, which is to advance the queenside's pawns. 16... f6d6  17. f3f4  17... g7g5 Lee tries to open the game on the kingside.
