1. g1f3  1... d7d5  2. g2g3  2... g8f6  3. f1g2  3... e7e6  4. e1g1  4... f8e7  5. d2d3  5... b8c6 Not a very common idea against the King's Indian Attack. 6. b1d2  6... e6e5 Deac enters the Pirc, down two tempi. Even this approach seems playable. 7. e2e4  7... d5d4 As long as Black does not open the center! 8. d2c4  8... f6d7  9. a2a4 A solid approach by Caruana. 9... e8g8  10. b2b3  10... f8e8  11. h2h4 The plans for both sides are clear. Caruana will try to mate the  opponent on the kingside whereas Deac would try to keep him busy on the  opposite flank. Both players have problematic bishops, locked behind their pawn chains, and need to solve their problems too. 11... e7b4  12. c1g5  Slightly weakening the kingside. 12... f7f6  13. g5d2  13... a8b8 In  preparation of b7-b5. 14. h4h5  14... a7a6  15. a4a5 Once again, Caruana tries to force a small concession by his opponent. 15... d7f8
