Thank you Jermann for your reply and confirming my guess. Real sacrifices are a part of the arsenal of very few GM, the likes of Alekhine, Kasparov, Keres, Tal, Shirov, Speelmann, these are the GM I know, so my apologies if I left any other out. It is interesting to see that CS Tal is able to find the best move, and because I don't have a copy of CS Tal, I would like to know if CS Tal is able to find the continuation, that is after the moves: 12. Bxh7 Kxh7 13. Ng5+ Kg6 14. Qg4 f5 15. Qg3 Kh6 16. Qh4+ Kg6 17. Qh7+ Kf6 the following position arises: r1bq1r2/pp2n1pQ/4pk2/2n2pN1/8/2N1P3/PP3PPP/R4RK1 w - - 0 18 the best move is 18. e4! which Capablanca played. My chess engines, CM 6000, Fritz 5.16, Junior 5.0, Hiarcs 6, failed to find this move also. Another sacrifice to open up the position. However, when I played the game out with the best move 18. e4! it has been shown that White does indeed get enough compensation for the piece sacrifice, and Black NEEDS TO FIND THE MOST ACCURATE MOVES in order to save the game.
