 | | perfidious: Is this really that easy?
I must admit, the interference idea sprang to mind fairly quickly, but this is hardly one of those slambang early-week POTDs. |
|
Mar-28-23 | | Brenin: 19 Rc5 wins Black's Q, since 19 ... Nxc5 allows 20 Bxe5 with mate. |
|

 | | northernfox: I got this one right, but it somehow seemed more complex than a Tuesday. Still, great start to the week: 2 for 2. |
|
Mar-28-23
 | | perfidious: As an aside: this may well have been a more suitable, though more complex, POTD starting one move earlier. |
|
Mar-28-23 | | Cheapo by the Dozen: I love Tuesdays!
Frankly, the last thing I noticed was that Black's queen also guarded the bishop. Until seeing that, I was trying to figure out which order for the first two moves was better. :) |
|
Mar-28-23 | | Mayankk: Black has a terribly weak a1- h8 long diagonal since the King has been boxed in by its own pieces in a corner with zero mobility. And just to be more generous to White, it has also ensured its Queen has no safe squares either to move in case of a crisis. White can exploit these themes by 19 Rc5. While it threatens to capture Queen, the bigger threat is 20 Bxe5+ Rf6 21 Bxf6#, should the Rook be taken by 19... Nxc5. |
|
Mar-28-23 | | King.Arthur.Brazil: I think that this is not so 'easy', if I did it right: 19. d4 Bxd6 20. d5+ Be5 21. Bxe5+ Nxe5 22. Rc5 and the King becomes happy to capture enemy's ♕ for sure. But, there must be something better that our friend <Brenin> must told, before my words... |
|
Mar-28-23 | | jrredfield: I saw right away that Black's Q was on the verge of being trapped. I kept trying to make 19 Rc5 work, but didn't realize that 19 Rc5 Nxc5 would result in a quick mate sequence after 20 Bxe5. So I settled on 19 Bxe5+ which essentially puts White a pawn ahead, certainly weaker than 19 Rc5 which wins the Q. |
|
Mar-28-23 | | Refused: 19.Rc5 is lights out
The knight on d7 has to protect the Bishop on e5 was the Black King is positioned very unfortunately. Thus the queen will drop and it's 1-0. |
|
Mar-28-23 | | geeker: 19. Rc5 is pretty obvious, and the first candidate move I saw after a few seconds of thought. But the subsequent complications are a bit tough for a Tuesday puzzle. |
|
Mar-28-23 | | Velmirovic: 19. Rc5 is curtains. Alarm bells should have been ringing with Black's king opposite White's dark-square bishop. |
|
Mar-28-23 | | saturn2: 19. Rc5 spotted soon.
Black starts with a piece more but is vulnerable on the a1 h8 diagonal and the queen limited space. |
|
Mar-28-23 | | mel gibson: It took me quite a while to confirm that.
There were many moves to consider and then reject.Stockfish 15 says:

Mar-28-23 | | agb2002: White is one knight down.
The knight on d7 is overloaded with the defense of e5 and c5. Hence, 19.Rc5: A) 19... Nxc5 20.Bxe5+ Rf6 21.Bxf6#.
B) 19... Bxb2 20.Qxb2+ Nf6 21.Rxb5 axb5 22.Qxb4 Rxa4 23.Rxa4 bxa4 25.Qxa4 wins decisive material. C) 19... Nd5 20.Rxb5 axb5 21.Nc5 Rxa1+ 22.Bxa1 Bxa1 23.Nxd7 C.1) 23... Rd8 24.Qa5 Rxd7 (24... Bf6 25.Nxf6) 25.Qxa1+ Rg7 26.d7 wins. C.2) 23... Ra8 24.Bxd5 Bxd5 25.Nb6 Rd8 26.Nxd5 cxd5 27.Qa5 Bf6 28.Qxb5 wins decisive material. D) 19... Nxd3 20.Rxb5 axb5 21.exd3 bxa4 22.Bxe5+ Nxe5 23.Qc3 Rfe8 24.f4 wins decisive material. E) 19... Rfe8 20.Rxb5 axb5 21.Qxb4 bxa4 22.Bxe5+, followed by Qc3 and f4, wins decisive material. |

 | | Teyss: I thought 19.Bxe5+? Nxe5? 20.Rc5 wins, but then saw 19...Qxe5. So I remembered "When a sequence doesn't work, try inversing the move order." |
|
Mar-28-23 | | AlicesKnight: Found Rc5. There are several responses, all losing material. |
|
Mar-28-23
 | | scormus: A rather messy position, but 19 Rc5 is clear enough. After that there's no way back for B, despite numerous plausible follow on sequences. Nice ending to put put it completely to bed. |
|
Mar-28-23 | | Brenin: White is a N down, so winning Q for R is not in itself a knock-out blow. What makes this work is that the subsequent exchanges leave Black with shattered Q-side Ps and poorly coordinated R+2B, and with the DSB shut out from the K's defence by 25 d4. This leaves White's Q+N free to attack the K, with the P lurking on d6 another potent threat. |
|
Mar-28-23 | | Nosnibor: Rc5 is a nice interception. |
|
Mar-28-23 | | TheaN: <19.Rc5 +-> is proper interposing, given 19....Nxc5 20.Bxe5+ Rf6 21.Bxf6#. In addition, it traps the queen: this is why this works because White wins material. Still work to do, but should be winning. |
|
Mar-28-23 | | Mayankk: Black refused to provide his King with any escape squares even after 8-10 moves into the attack. It served him rather well that in the last position, the King can only wait for a mercy killing by 28 Nxg6# (or 28 Qxh7# if the Bishop finally moves). He probably suffered from a masochistic tendency of suffocation. |

 | | takebackok: Easy peasy Tuesday, Sharp play by Planinc after winning the Q. |
|
Mar-28-23
 | | takebackok: If instead of 23...Ra8, 23...Bc3 24 Qxc3+ Nxc3 25 Nxf8 & pawn Qs |
