      I think 1.Nd4 (either one) is not insane enough for Stachu's standarts .

      Perhaps 1.Ba3 is ?

      (Note I am not saying it is the best move here - although it could be- but it has certain swindling potential.)
      There are only three kinds of chessplayers: Those who can count and those who cannot.

        Dear friend,

        For once, insanity is where you want it to be, I don't decide on that. Secondly, both 1. Ba3 and 1. Ncd4 work if white takes the knight on b5, however, the best defence for the former move is Nh5, latter Bd3.


        position after 1... Ncd4 2. Bd3 Ba3 3. Nge4 Bxb2+ 4. Kxb2 Qa3+ 5. Kb1
        draw, unless black opts for 2. Nd6 after 2. Bd3. That is definitely better than drawing so fast, and the position would be about equal, with chances for both sides (white can generate some initiative with Qh3, Nh5 and Rhg1). But as you can imagine, I wouldn't put up the puzzle which requires you to play two moves and say that the position is about equal.


        position after 1... Ba3 2. Nh5 Ncd4 3. Bxb5 axb5 4. Qxg7+ Qxg7 5. Nxg7 b4 6. bxa3 bxc3 7. Be3 Ne2+ 8. Kb1 Bc6 9. Rhe1
        about equal, but since the ladies are off the board it will probably end up in a draw. Objectively, that move is slightly better than 1. Nd4, though.

        But there is a brilliant move in this position. It can also end up in a draw, but the line is twice as long and a lot more forceful (and that would make defending a lot harder and attacking easier).

          Well, we really wouldn't want to move the knight from b5, since it can be sacrificed to unleash the rook on a8. We also would like to unleash the rook on c8, but at the same time we have to disallow Bd3/Nh5. So...........Nb4!!

          position after 1... Nb4 2. axb5 (forced, otherwise if Bd3 then Nxd3 is winning, if Nh5 then Nd4 is winning) axb5 3. Be3 (forced, defending against Ra1#) Rxc3 4. bxc3 Bf6 (instead of the natural Na2+ going for coordination is better) )5. Bd4 Bc6 6. Qh3 Na2+ 7. Kd2 e5 8. Be3 Nxc3 9. Qe6+ Kh8 10. Rhg1 e4 11. Ke1 Nxd1 12. Bxd1 Rd8 13. Bd2 h6 14. Qb3 Bd4 15. Be3 Bd5 16. Qb1 Bxe3 17. fxe3 Bc4 18. Be2 Qa3 19. Bxc4 Qxe3+ 20. Ne2 Qd2+ 21. Kf1 bxc4 22. Rg2 Rf8+ 23. Rf2 Rxf2+ 24. Kxf2 e3+ 25. Kf1 Qd5 26. Qe1 Qf5+ 27. Kg2 Qxc2 28. Kf3 Qf5+ 29. Kxe3 b5 30. Kd4 Qe6 31. Qf1 b4 32. Qf3 b3 33. Qe4 Qxe4+ 34. Kxe4 Kh7 35. Kf5 g6+ 36. Ke5 g5 37. hxg5 hxg5 38. Nc3 Kh6 39. Nb1 Kh5 40. Kd4 g4 41. Ke3 Kh4 42. Nc3 g3 43. Nd1 Kh3 44. Kd4 g2 45. Nb2 g1=Q+ 46. Kxc4
          black is winning. Natural 9. Qe6+ is not the way to go due to e4 and Bd4.

          Instead white should opt for:

          position after 1... Nb4 2. axb5 axb5 3. Be3 Rxc3 4. bxc3 Bf6 5. Bd4 Bc6 6. Qh3 Na2+ 7. Kd2 e5 8. Be3 Nxc3 9. Ra1 Qd6+ 10. Bd3 Rd8 11. Nh5 e4 12. Qf5 exd3 13. Nxf6+ Qxf6 14. Qxf6 Ne4+ 15. Kc1 gxf6 16. cxd3 Rxd3 17. Rd1 Rxd1+ 18. Kxd1
          about equal. Perhaps Nd6 is the best move here.

            - How to determine quality of a move, how do I know that 1. Nb4 is better than 1. Ba3?

            Two questions need to be anwered here:
            1. What the move does?
            2. How does it do it?

            1. Nb4
            1a. It gets the knight closer to white king, threatening Na2+ (at some point) and controlling d3 square.
            1b. it clears the path for the rook on c8.
            1c. the hardest part: because it forces the reply axb5, it clears the path for the rook on a8. So really, in terms of development, 1. Nb4 activates three pieces, two of which are heavy ones.
            2. One rule here: the more forced the line the better (Frankly, I didn't even analyse Ncd4/Ba3/Nbd4 unless I had to reply - Nb4 is very forceful and for me it was forced enough not to look elsewhere.)

              Let's answer another one:

              - Why is forced better?

              Let's assume that player A is attacking and player B defending. Then, if A chooses the most forced line:
              1. A doesn't have to worry about B's plan, he can focus more on his own.
              2. B doesn't have time to improve position of his pieces, instead he has to forcefully react to our threats, and for the most parts sit and wait for his king to be hunted down.

              ...and this is where the strength lies
