Here there is the old dilemma: where to place the bishop, on c5 or e7 $2 Chess players have been trying to answer this question for decades, but the answer is still inconclusive.
1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f6e4 The open Ruy Lopez is one of the best defenses for Black, but it's not the most popular among the elite, so it ends up being a small and pleasant surprise for me to see it employed in the first round. 6. d2d4  6... b7b5  7. a4b3  7... d7d5  8. d4e5  8... c8e6 There are countless ways to face this variation as White. To the delight of the spectators, both players are very well-prepared, have new ideas, and are uncompromising fighters. The game quickly steers away from the beaten path, which in this opening can sometimes extend into incredibly long variations.
