1. g1f3  1... d7d5  2. e2e3  2... g8f6  3. c2c4  3... e7e6  4. b2b3 This is usually Nakamura's weapon of choice in blitz and rapid events. 4... f8e7  5. c1b2  5... e8g8  6. g2g3 A funny move, as we are usually told that you should not combine e3 and g3 in the opening. But, to be honest, it does not make a huge difference in the evaluation of the position. Of course White can play more pragmatically with moves like 6.c3 or 6.Be2. Duda even tried the crazy 6.Rg1 followed by 7.g4 in a rapid event this year. Not something you should do, unless you are 2700+ and want to have fun in a dubious position. 6... b7b6  7. f1g2  7... c8b7  8. e1g1  8... c7c5
