comment: This is probably best, although the position is not easy to play since Black cannot castle - the rook needs to protect the h-pawn.
context: 1. c2c4  1... e7e6  2. b1c3  2... d7d5  3. c4d5  3... e6d5  4. d2d4  4... f8e7  5. c1f4  5... c7c6  6. e2e3  6... c8f5  7. g1e2 I've played this move twice during my career, once against renowned GM, coach, and opening expert Rustam Kasimdzhanov. 7... b8d7  8. e2g3  8... f5g6  9. f1e2  9... g8f6 The most solid option. 10. h2h4 Black now needs to decide whether to play the pawn to h6 or h5.
