1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. d2d3  4... h7h6 Dubov's pet move with which he  won a few beautiful games last year (see below). 5. b1c3  5... f8b4  6. e1g1  6... b4c3  7. b2c3  7... e8g8  8. c4b3 Not a common continuation  but a logical move. The bishop steps back in anticipation of the imminent  central break d7-d5. 8... d7d5  9. e4d5  9... f6d5  10. h2h3 This pawn sacrifice turns out to be  dubious, to say the least. 10... d5c3 Dubov accepts the sacrifice and quickly spots an  important attacking detail.
