1. g1f3  1... g8f6  2. c2c4  2... e7e6  3. g2g3  3... d7d5  4. f1g2  4... d5d4 One of the popular ways of meeting the Reti these days. Black enters a reversed Benoni, down a couple of tempi. 5. e1g1  5... b8c6  6. e2e3 The most direct approach. White wants to make the most of his lead in development and needs open files. 6... e6e5 Keymer enters a forcing line. 7. e3d4  7... e5e4  8. d4d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] And here comes a star novelty $1 8... e4f3 Keymer took the knight quickly, but sank into deep thought after 9. d1f3  9... c6e5 Self-pinning. There was a lot to think about, since the knight is not safe anywhere. 10. f1e1  10... d8e7 The X-ray threats along the open file makes Black's previous move possible. 11. f3d1 [%c_effect d1;square;d1;type;GreatFind;persistent;true] An only move $1 Esipenko blitzes his moves out. 11... c8g4 Played after another long think. The game is forced again.
