6)...,c6 more often c5 is played by black to challenge the d4 pawn.8)..., a5 black now launches an attack on the a file, his white bishop is boxed in on c1 by the problem b7 pawn. 9) Ne5 and also c4 are key moves for white
10) f4 prepares to free the rook on the f file
15) Black is passive and his position is cramped |

| Jan-30-24 | | Mayankk: So many White pieces are hovering around the Black King that it seems only a matter of time. The King has no escape squares and any unanswered check will be mate. By trial and error, we can quickly identify 21 Ngxf7 Nxf7 22 Ng6# as one such possibility. Now does Black have another option after 21 Ngxf7 ? 21 ... Nf6 seems the best try. But it still fails to 22 Nxh8 Nxh7 23 Qh5 Ng5 (to safeguard against Qf7#) 24 fxg5 and 25 Qf7#. So yeah 21 ... Nxf7 was a help-mate but the alternatives are no better. |

| Jan-30-24 | | King.Arthur.Brazil: Maybe, my namesake had hoped something like: 21...Nxe5 22. Nxh8 g5 23. Qh5 Kg7 24. Qxh6+ Kxh8 25. Bg6+ Kg8 26. Qh8#. On 23... Bf6 24. fxg5 Bxh8 25. Rf1+ Ke7 26. dxe5 Bd7 27. Qf7+ Kd8 28. g6, etc. Or even: 24. Ng6+ Nxg6 25. Qxg6 Bg7 26. fxg5 hxg5 27. Rf3+ Ke7 28. Qxg7+ an the attack continues. The alternative 23. Qxe5!? also seems to win: Qd6 24. Ng6+ Kf7 25. Nxe7 Qxe7 26. fxg5 (Qxg5 27. Rf1+ Ke7 28. Bc1 win our beloved enemy's ♕ ) with an extra ♗ and attack. |

 | | master8ch: A seemingly more reasonable defensive attempt by Black leads to virtually the same ending: 21.Ngxf7 Nxe5 22.Nxh8 Nc6 23.Qh5 Nd8 24.Qf7+ Nxf7 25.Ng6++. |

| Jan-30-24 | | Cellist: I was deciding between 21. Ngxf7 and 21. Qh5. The latter also leads to a clear advantage for White (+1.78), but I did luckily settle for the former, which is much stronger. I did not expect Black to walk into the mate, however. |

| Jan-30-24 | | jffun1958: 21. Ngxf7 Bf6 22. Nxh8 Ke7 23. Nhg6+ Kd8 24. c4 Bxe5 25. Nxe5
and W is up a piece and a pawn. |

 | | PawnSac: ok lets see..
After 21.Ngf7 black can't take Nf7 because of Ng6 smothered mate. So lets look at options:21.Ngf7 Nxe5 22.Nxh8 Nd7? 23.Qh5
21.Ngf7 Nxe5 22.Nxh8 Nc6 23.Qh5 Nd8
24.Qf7+ Nxf7 and there's the Ng6# again! lol
ok how about
21.Ngxf7 Nxe5 22.Nxh8 Bd8 23.Qh5 Qc7 24.fxe5 (now 24..Ke7? Qf7#) and black is scrambling to find any moves. I'm getting the impression 21.Ngf7 is the move.
The only escape seems to be.. 21. Ngxf7 Bf6 (creating a flight square) 22. Nxh8 Ke7 23. Nhf7 Bxe5 24. Nxe5 Kd8 running away but black is down a bishop and pawn with a crappy position. This is one of those positions that collapses like a house of cards. Everything loses. |

| | PawnSac: What?? he DID overlook Ng6# !!
good grief! lol |
|
| Jan-30-24 | | TheaN: Bit late to the party here, but <21.Ngxf7> can be played for free, given 21....Nxf7 22.Ng6#, which was played. White is also threatening Nxh8 himself, and there are no real ways to fix that. I only really considered <21....Nxe5> but this doesn't really prevent <22.Nxh8 +-> with Qh5 coming. After Bf6 and Nf6 it's the same: the knight on h8 actually finishes the mating net. |

 | | gawain: If after 21 Ngxf7 Black creates an escape square with the pawn move 21...g5 he can stave off the mate until move 33. It's hopeless, but the mating net is surprisingly hard to close. |
