1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. f3g5 The last time Van Foreest played  this line was in 2015. 4... d7d5  5. e4d5  5... c6a5  6. c4b5  6... c7c6  7. d5c6  7... b7c6  8. b5d3  8... f6d5  9. g5f3  9... f8d6  10. b1c3  10... e8g8  11. d3e2  11... d5f4  12. e1g1 White's play seems very slow, but as long as his king is in safety he can afford playing like this. 12... c8g4  13. d2d3  13... f4e2 The bishop was an important defender. 14. d1e2  14... f7f5 Now the pin along the h5-d1 diagonal looks scary and Carlsen wants to open all the  files with e5-e4. 15. h2h3  15... g4h5  16. g2g4 A strong novelty!  Apparently, Van Foreest did a very thorough preparation for the  tournament. 16... f5g4  17. f3g5 The point behind Van Foreest's operation. A strong blockading  knight will a secure stable kingside for White and will keep the black  bishops away from his king. 17... d8d7  18. c3e4 Another strong maneuver. The knight is heading to g3. 18... d6e7  19. e4g3  19... h5g6  20. e2g4  20... d7g4  21. h3g4 The novelty worked perfectly for  White. He enters the endgame as a clear favorite. 21... c6c5 One idea is to trade the isolated pawn. Another, to bring the knight back into the  game. 22. g5e4  22... a5c6  23. c1e3  23... c6d4  24. a1c1  24... a8c8 This prepares the c5-c4 advance. 25. g1g2 A useful move. White is stepping out of the possible knight  forks. 25... c5c4 A move with lots of merits. It opens files and diagonals  for the black pieces, softens the position of the blocking knight on e4  and trades a possible weak pawn. 26. e3d4  26... e5d4  27. f2f3  27... c8c6  28. b2b3  28... e7a3  29. c1e1 Now Black is fine. 29... c4d3  30. c2d3  30... a7a5 The same policy as before. The a-pawn will be traded, thus creating a weakness in White's camp. 31. f1f2  31... a3c1 Now it is  the world champion who is pressing. In the endgame the bishop pair often  compensates with interest an extra pawn for the opponent. 32. e4d2 A  clever decision! White found a way to swap one of the black bishops and  liquidate into a draw endgame. 32... g6d3  33. d2c4  33... c1f4  34. c4e5  34... c6c3  35. e5d3  35... c3d3  36. g3f5  36... g7g6  37. e1e4  37... f4g5  38. f5e7  38... g8h8  39. e7c6
