1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. h2h4 \"I had not checked this thoroughly until  yesterday.\" (Shankland) 3... f8g7  4. b1c3  4... d7d6 Svidler surprisingly switches to the KID. 5. e2e4  5... b8c6  6. g1e2  6... e8g8  7. f2f3  7... e7e5 Now it is a form of the Samisch, but with  a pawn on h4 in return for the generally more useful Nb8-c6 move. Still,  h2-h4 is not bad to have in this setup. 8. d4d5 Shankland is  confidently executing his moves, this novelty included. 8... c6d4  9. c1e3  9... c7c5 Svidler will sacrifice it anyway. 10. d5c6  10... b7c6  11. e2d4  11... e5d4  12. e3d4  12... a8b8 In return for the pawn, Black gets the half-open b-file for  his rook and prolongs the diagonal for his dark-squared bishop. His  presence in the center becomes more significant too. 13. d1c2  13... c6c5  14. d4f2  14... c8e6  15. e1c1 The most natural move. Shankland is  still in his prep. 15... f6d7 \"He was supposed to be worse after this move [according to  the computer].\" (Shankland) The sacrifice of a second pawn is once more a no-brainer for a King's Indian player. 16. d1d6  16... d8a5  17. f2e1  17... d7e5 Svidler  has rapidly improved his pieces, and his opponent decides to part with one of the pawns in order to lower their attacking potential. 18. f3f4  18... e5c4  19. f1c4  19... e6c4  20. e4e5  20... f8d8 Svidler on his turn swaps off  the active white rook. 21. d6d8  21... b8d8  22. h4h5 Shankland needs to play  on his own, and this brings his sweet fruits earlier than expected. 22... c4a2 Now the pawns are equal, and White opens files on his own.  The battle rapidly heats up... 23. h5g6  23... h7g6
