| Apr-08-22 | | Brenin: 20 Bxe7 was not hard to find, but iit took me a while to see exactly whiy it works. If 20 ... Nxc3 then 21 Bf6 (forking R and N, and threatening Qxd6 and Qe7 mate) Qc7 22 Qxc3 is good for White. If 20 Kxe7 then 21 Qxd6+ Ke8 22 Rxc6 bxc6 23 Qxc6+ Ke7 (23 ... Kf8 24 Qxa8+) 24 Bc4 with unstoppable threats, e.g. Qb7+ followed by Qxf7 mate). However, not the tempting 24 Rd7+ Kf8 25 Qxa8+ Kg7 when Black threatens both Rxa8 and Qe1+ with mate to follow, so 26 Qxa7 Qe1+ 27 Qg1 Qxe2, allowing Black to fight on with N for 4P. |

I wanted to play 24. Rd7+. But after that there's no way white can win the rook on a8 and keep up the attack without allowing a back-row mate. 25. b4 is the real key. It's an enormously effective move. |

| Apr-08-22 | | AlicesKnight: Found the right moves, not necessarily in the right order ..... |
|
| Apr-08-22 | | Brenin: A correction to my earlier kibitzing. After 20 Bxe7 Kxe7 21 Qxd6+ Ke8 22 Rxc6 bxc6 23 Qxc6+ Ke7 24 Rd7+ Kf8 25 Qxa8+ Kg7 26 Qxa7 Qe1+ 27 Qg1 Qxe2, Black cannot <fight on with N for 4P> since White has a mating attack starting with 28 Qd4+. Even so, I think 24 Rd7+ is inferior to 24 Bc4 and to the game line 24 Qd6+. |
|
| Apr-08-22 | | parch: Did not see it at first, 20.B:e7 (second brew ) 20...N:c3 (20...K:e7 21.Q:d6+ Ke8 22.R:c6! bc6 23.Q:c6+ ) 21.Bf6 Qc7 22.Q:c3 Rh6 23.Bg5 Rh7 24.Qf6 Rd8 25.e5 looks OK. |
|
| Apr-08-22 | | TheaN: I did spot <20.Be7> relatively quickly but got a bit lost in variations. <20....Kxe7 21.Qxd6+ Ke8> seemed rather obvious, if Black doesn't take on e7 his king is perpetually confined to the center. Not sure what the best 22th move would be, I would have played <22.Rxc6> as it's most consistent. I looked at b4 for a long time but couldn't make Nxc3 work; typically, that wins for White, whereas Rd8! is a draw. <22....bxc6 23.Qxc6+ Ke7> and again we're at crossroads. Rd7+ is obvious, yet runs into Kf8 25.Qxa8+ Kg7 where 26.Qxa7 is forced, 26....Qxa7 27.Rxa7 Rc8! 28.h4 Nxb2 +- and White has some work to do. Instead <24.Qd6+! Ke8 25.b4! +-> removes all counterplay, as White sets up Bb5 or Qc6 with the same line as before, but now without the threat of Qe1+. |
|
| Apr-08-22 | | parch: On 20...K:e7 21.Q:d6+ Ke8 22.R:c6
Black could reply, 22...Rd8 23.Rc8 R:c8 24.Qd7+ Kf8 25.Q:c8+ Kg7 26.Q:b7 Nb6
(preventing Bc4 ) |

| Apr-08-22 | | agb2002: White has the bishop pair for a bishop and a knight. Black threatens Nxc3.
White can expose the black king with 20.Bxe7:
A) 20... Kxe7 21.Qxd6+ Ke8 22.b4
A.1) 22... Qd8 23.Qe5+ Qe7 24.Qxh8+ wins decisive material. A.2) 22... Rd8 23.bxa5 Rxd6 24.Rxd6 + - [R+2P vs n]. A.3) 22... Qg5 23.Rxc6 bxc6 24.Qxc6+ Ke7 (24... Kf8 25.Qxa8+ Kg7 26.Qc6 -prevents Nc3- wins three pawns) 25.Rd7+ Kf8 (25... Ke8 26.Rd5+ wins the queen) 26.Qxa8+ Kg7 27.Qc6 wins three pawns. B) 20... Nxc3 21.Bf6
B.1) 21... Nxd1 22.Qxa5 Rh6 23.Bd4 wins decisive material. B.2) 21... Rg8 22.Qxd6 wins (22... Qd8 23.Qxd8+ Rxd8 24.Rxd8#). B.3) 21... Rh6 22.Bxc3, with the double threat Bxa5 and Qxh6, wins decisive material. |
|
| Apr-08-22 | | agb2002: My first idea was to play 22.Rxc6 but after 22... bxc6 23.Qxc6+ Ke7 24.Rd7+ Kf8 25.Qxa8+ Kg7 White looked to me lost due to Qe1+ and Rxa8. However, White had 26.Qxa7 Qe1+ 27.Qg1 Qxe2 28.Qd4+ Kg6 29.Qd6+ and mate soon (29... Kg7 30.Qe5+ Kg6 31.Qf5+, etc.). Very instructive. That's why I chose 22.b4, overlooking 22... Rd8. I missed also 21... Qc7 in my line B, although after 22.Qxc3 White seems to have more than adequate compensation for the rook. |

| Apr-08-22 | | TheaN: <henilsson: Chrisowen: i hate to repeat myself, but WHAT!?> Seems like you're new here: chrisowen's been posting these semi-autogenerated posts on the daily puzzle for as good as a decade now. Nobody really knows where the setup comes from, but every post does contain the solution so it's not fully automatic. It stopped bothering me a good while ago; I think CG allows it as a tradition. He responds if you quote him and sometimes answers posts that follow his directly which is mildly funny. If you really don't want to see it just ignore him, given you're premium. |

| Apr-08-22 | | King.Arthur.Brazil: I found the main combination but I felt in doubt about how to continue, so move 25.b5! is the difficult. Obviously, direct 26.♖d5 fails due to 26...♕e1+. After, the previewed 25...♕g5 26. ♖d5 ♕c1+ 27. ♗d1 f6 28. ♕e6+ ♔f8 29. ♕xf6+ ♔g8 30. ♖g5+ ♔h7 31. ♕g7# or 29... ♔e8 30. ♕e6+ ♔f8 31. ♖f5+ ♔g7 32. ♕f7+ ♔h6 33. ♖xh5# with unavoidable check-mate. Other Black moves like 26... ♕e7 27. ♖e5 ♕xe5 28. ♕xe5+ ♔d7 29. ♗b5+ ♔c8 30. ♕xh8+ ♔b7 31. ♗c6+ ♔xc6 32. ♕xa8+. Cases like 26...♕g6 or 26...Th6 is answered with 27. ♗b5# or depending also 27.♖e5+(#). The sacrifice: ♕xd5 27. ♕xd5 ♘b6 28. ♕e5+ ♔d7 29. ♗b5+ ♔c8 30. ♕xh8+ ♔b7 31. ♕xh5 ♖c8 32. ♕xf7+ ♖c7 33. ♕f4 and White wins simply. |
|
| Apr-08-22 | | King.Arthur.Brazil: The King (who else? Me, of course) supposes that Black answer to the sacrifice could be 20...♘xc3 21. bxc3 ♔xe7 22. ♕xd6+ ♔e8 when it is uneasy to find White way to win immediately and it is a second puzzle. |
|
| Apr-08-22 | | Brenin: <King.Arthur.Brazil>: White's best answer to 20 Bxe7 Nxc3 is not 21 bxc3 but 21 Bf6, forking the pinned N on c3 and the R on h8, and also threatening 22 Qxd6 followed by Qe7 mate. |
