Big complications start from now on. Instinctively we can see that the position is very promising for White, with several attacking possibilities against the black king. The central theme of this game is \"Candidate Moves\", the term created by GM and renowned author Alexander Kotov and which is so debated to this day. Both sides will have plenty of options on almost every move during the middlegame.

White's play isn't very difficult and although he doesn't have an objective advantage, I can say that nothing gives him an advantage against this solid defense anywway. 5... e4c3  6. d2c3  6... f8e7  7. c1f4  7... e8g8  8. d1d2  8... b8d7  9. e1c1  9... d7b6 [%c_effect b6;square;b6;type;Inaccuracy;persistent;true] A rare move, never played by a GM before. The b6-square seems a little strange for the knight, as it doesn't have a very large range of action. 10. f1d3  10... d6d5  11. h2h4
