"A very bad move." (Mamedyarov) The knight will not even reach the c5 square.
1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. c2c3  4... g8f6  5. d2d3 "I did not mind positions  that looked slow at first sight." (MVL) The more pieces there are on the  board, the more difficult the decision-making is for the side that craves  the draw. A similar approach was chosen by Kasparov in the famous last  match game against Karpov, Sevilla 1987. 5... d7d6  6. e1g1  6... h7h6  7. f1e1  7... e8g8  8. h2h3  8... a7a5  9. b1d2  9... c8e6  10. c4b5  10... d8b8  11. d2f1  11... b8a7  12. c1e3  12... c5e3  13. f1e3 "I had a lot of blitz games in this position  against Hikaru [Nakamura]" (MVL) 13... c6e7  14. a2a4  14... a8d8 A novelty  which prepares c7-c6 followed by d6-d5 and basically forces the trade of  the second bishop. 15. b5c4  15... e6c4  16. e3c4 As the French GM explained the feeling that Black  should be doing perfectly fine is deceptive. The knight on c4 stands very  well, whereas if Black tries bringing his one to the alternative c5  square, then the central advance d3-d4 will become unpleasant.
