  1. e4 c6 2. Nc3 d5 3. Nf3 (SF 14.1 prefers 3 d4) 3…dxe4 (SF121050 @depth 47 will play this move, the second most often played move, with 2210 examples in the ChessBaseDataBase, but SF 15 @depth 44 prefers 3…Nf6, a move having been made only 840 times, according to the CBDB. Then there is the most often played move of 3…Bg4, the favorite of Komodo @depth 33, which can be found in 4536 games at the CBDB) 4. Nxe4 Nf6 5. Qe2 (The most played move thus far with 1166 examples contained within the bowels of the CBDB, but is it the best move? Fritz 17 @depth 29 calculates it best, as does Komodo @depth 34. Then there is the Big Fish, Stockfish 15 @depth 64, which has come to the conclusion 5 Nxf6+ is better than any other move. In 596 games it has scored only 51%; Qe2 shows 52%. Then there is 5 Ng3, a move yet to be mentioned, that has been attempted in 150 games while scoring 56%! I like the smelly Fish, but regular readers will know only a meat cleaver would prevent me from moving the Lady to e2, where she belongs…) 5…Na6 (Stockfish 9 [Nine? Are you kidding me?] @depth 41 plays the move, and it has scored very well, holding white to only 44% in the 27 games contained in the CBDB. Fritz 16 @depth 38 will play the most often played move, 5…Nxe4, which has scored 52% in 928 games. Fritz 18 will play 5…Bg4. In 84 games it has scored 55%) 6. Nxf6+ (With 18 games this has been the most often played move, and it has scored 50%, but SF 14 @depth 37 and SF 14.1 @depth will play 6 a3, a move yet to be tested by a human. Komodo 14 @depth 36 will play a TN of its own, 6 c3) 6…gxf6 7. h3 (SF 13 plays the most often played move, 7 d4, which has only scored 31%; SF 14 plays 7 a3, a move not found in the CBDB; and SF 15 will play 7 d3, and so should you)
