Jan-08-19 | | OrangeTulip: You really have to see the mate pattern in a split second. If not start training tactics, and forget openings |
|
Jan-08-19 | | AlicesKnight: Found 17.Bb6 - deflecting the Q or winning at least a piece. |
|

 | | Dionysius1: That's really bad advice! Why totally forget openings? |

|
Jan-08-19
 | | perfidious: <saturn2>, 15.Bxd7+ and 16.Qxe5+ offers no succour. |
|
Jan-08-19 | | zb2cr: Count me among the 17. Bd7+ crowd. |
|
Jan-08-19 | | saturn2: <perfidious> thx. So 13...white to play is for wednesday or thursday. |
|
Jan-08-19 | | thegoodanarchist: I feel as if I've seen this before, in a tactics puzzle book or software... |
|
Jan-08-19 | | et1: Qd7 Qtakes Bd7 + does not work ? |
|
Jan-08-19 | | Henrychn: If 13...Nxd5, what¡¯s the white¡¯s response? |
|
Jan-08-19 | | Henrychn: Sorry, 13...cxd5 |
|
Jan-08-19 | | BOSTER: < devere>:<17. Bb6 losing a piece>. This is correct, but is more attractive to play Bb6 when black king on d8. So 17.Bd7+. |

<17.?>
A relatively simple concept deflection with <17.Bb6>, but the position screams for so much more. Alas. Stockfish does something interesting: it starts with 17.Bd7+ Kd8 18.Bg4+ Ke8, only now to play 19.Bb6. It does take out Black's castling which is useful, but is seemingly evaluating less than 17.Bb6 immediately which doesn't make sense. Can White do more with these very strongly placed pieces? No, surprisingly. After the main line <17.Bb6 Qd6>, <18.Bd7+?!> is not theoretically better than just Qxd6 straight away, due to <18....Kxd7! 19. Qc1 +-> and White's winning, but not more than by just taking the piece and paralyzing Black. |
|
Jan-08-19 | | nasher: <TheaN> I agree that Stockfish starting with Bd7+ is strange, but it does NOT keep Black from castling ... Black's move 15 was Kd8. |
