1. e2e4  1... e7e5  2. f1c4  2... g8f6  3. d2d3  3... b8c6  4. b1c3 Quite a rare line in Esipenko's practice. 4... c6a5  5. d1f3 \"A specialty of the Australian grandmaster Ian Rogers.\" (Emms) 5... a5c4 That's too good of a bishop to be neglected $1 6. d3c4  6... d7d6  7. g1e2 Both sides make all the mandatory moves to finish the development. 7... c8e6  8. b2b3  8... f8e7  9. e1g1  9... e8g8  10. a2a4  10... f6d7 Nakamura would be happy to open up the position with either d6-d5 or (more likely) the f7-f5 break, and those require preparation. 11. a4a5 This is a novelty. White is threatening to push this pawn even further; however, he risks ending up with a queenside weakness. 11... a7a6 Fixing the pawn. 12. e2g3 White needs to take measures against the f7-f5 move. 12... e7g5  13. g3f5  13... g5c1
