Both 12.Re1 and 12.Rb1 are worthy alternatives.
1. c2c4  1... g8f6  2. b1c3  2... e7e5  3. g2g3  3... f8b4  4. f1g2  4... e8g8  5. e2e4 This variation of the English Opening is not very popular. White can't achieve an advantage against the plan used in this game. 5... b4c3  6. b2c3  6... c7c6 [%c_effect c6;square;c6;type;GreatFind;persistent;true] This accurate move gives Black a good position. 7. g1e2  7... d7d5  8. c4d5  8... c6d5  9. c1a3 This move is new but not very good. The bishop is not well placed on a3. 9... f8e8  10. e4d5  10... f6d5  11. e1g1  11... b8c6 Black is already better. We can conclude that something went wrong with Khotenashvili's preparation.
