1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... g8f6  4. d2d3  4... f8c5  5. c1g5 A relatively rare move. 5... c6e7 So comes with a novelty right away! His idea is typical:  the knight wants to get to g6 before the h-pawn advances. 6. g5f6 Van Foreest ruins the opponent's kingside at once. 6... g7f6  7. d3d4 The correct strategy is to remove the e5-pawn ASAP. 7... e5d4  8. e1g1 An accurate move. 8... c7c6  9. b5c4  9... e8g8  10. f3d4  10... d7d6  11. b1c3  11... f6f5 Van Foreest has regained the  pawn, whereas So has managed to advance one of his doubled pawns. Still,  the open black king requires him to be very, very careful. 12. d1d2  12... g8h8  And this obvious move does not seem right. 13. a1d1  13... c5b6  14. d4f3 Now there is a problem with the d6-pawn.
