| Jul-24-17 | | BxChess: I had 37. Rb2+ 38. Nxb2 Rxb2+ 39. Ka1 Rxc2+ 40. Rf6 Bxf6# |
|
| Jul-24-17 | | notyetagm: < ChessHigherCat: My version takes a move longer but hey, what's the rush?: 37. Rb2+ 38. Nxb2 Rxb2+ 39. Ka1 Rb1+ 40. Ka2 Ra1#> That's not mate, as 41 ♖h1x♖a1 is possible because 38 ♘d1x♖b2 cleared the back rank to allow the White h1-rook to help defend the White king. <ALL OF A SUDDEN> that White h1-rook participates in the defense. |
|
| Jul-24-17 | | ChessHigherCat: <raviarun> <notyetagm> you guys are right, the N isn't on the back rank anymore. Time for bed. |
|
| Jul-24-17 | | saturn2: Similar mate to last monday's: protected rook on the 7th rank, king in the corner and the knight checkmates. |
|
| Jul-24-17 | | drollere: i fixated a bit on the annoying N on d1, until i realized the R check and exchange would take it off the board. thank you, KB on g7! |
|
| Jul-24-17 | | stst: 37......Rb2+
38.NxR RxN+
39.Ka1 RxN dis+# |
|
| Jul-24-17 | | agb2002: Black has a bishop for a knight.
White is about to block the b-file with Nb4.
Black wins with 37... Rb2+ 38.Nxb2 (38.Ka1 Nb3#) 38... Rxb2+ 39.Ka1 Nb3#. |
|
| Jul-24-17 | | leRevenant: Easy Macadeasy, as it should be today. |
|
| Jul-24-17 | | morfishine: <37...Rb2+> mating soon: 38.Nxb2 Rxb2+ 39.Ka1 Nb3# ***** |
|
| Jul-24-17 | | malt: 37...Rb2+ 38.N:b2 R:b2+ 39.Ka1 Nb3# |
|
| Jul-24-17 | | whiteshark: <37...Rb2+ 38.Nxb2 Rxb2+> The replacement delivery is basically implemented to the initial performance location... <39.Ka1 Nb3#> |
|
| Jul-24-17 | | Iwer Sonsch: This king can be mated with brute force. Rb2+ Nxb2 Rxb2+ Ka1 Rxc2# wins material and the game. |
|
| Jul-24-17 | | Iwer Sonsch: Okay, Rxc2+ Rd4 Bxd4#. Still. |
|
| Jul-24-17 | | Whitehat1963: I chose the main line but preferred Rxc2 as the last move. |
|
| Jul-24-17 | | zb2cr: Ah, the famous "Rook reloader" strikes again, with 37. ... Rb2+; 38. Nxb2, Rxb2+; 39. Ka1. At this point, 39. ... Rxc2+ suggests itself, but it's not mate; White can interpose the Rook to stretch it out one move more. The alternative, 39. ... Nb3#, does deliver mate. |
|
| Jul-24-17 | | thegoodanarchist: Monday is Monday again!
After a series of Wednesday-level puzzles the last few Mondays, we get a Monday-level puzzle. |
|
| Jul-24-17 | | Pasker: So damn easy..That's monday |
|
| Jul-24-17 | | Rama: Finally got one! |
|
| Jul-24-17 | | patzer2: Today's Monday puzzle (37...?) is good for demonstrating a simple mate-in-three with a minor piece giving mate from the third rank after <37...Rb2+ 38.Nb2 Rb2+ 39.Ka1 Nb3#.> The game is also interesting because White misses several opportunities to win or draw before Black takes a decisive advantage. The most clear win White misses is the skewer 26. Bf4! when play might continue 26...Qb6 27. Na4  (+3.66 @ 28 depth, Stockfish 8.) Another winning or drawing possibility White misses is 28.Bd4! Ne8 29.Rxa6 Bxc2 30.Bxg7 Nxg7 31.Nd4 Bd3 (31...Rxb2? 32.Nc6 R8b3 33.Ra8+ Kf7 34.Ne5+ Kf6 35.Nxc4 Rxc3 36.Nxb2 +2.72 @ 27 depth Stocfish 8) 32.g4  to (+1.50 @ 30 depth, Stockfish 8). White's decisive mistake is <30. Ka2?> allowing <30...Nc5!  > (-4.27 @ 29 depth, Stockfish 8.) Instead, White can hold it level with 30.Ra5! when play might continue 30...Bf5 31.Rd5 Bd3 32.Nf4 Bxc3 33.bxc3 Bc2 34.Ka2 Nb6 35.Rd2 Bb1+ 36.Kxb1 Nd5+ 37.Rb2 Rxb2+ 38.Bxb2 Nxf4 39.Ka2 Nxg2 40.Bc1 Re8 41.a4 Ne1 42.Ka3 Nd3 43.a5 Rb8 44.Be3 Rb3+ = (0.00 @ 28 depth, Stockfish 8.) |
|
| Jul-24-17 | | kevin86: Rook sac leads to simple mate in 2 ways. |
|
| Jul-24-17 | | King Harvest: What a nice teaching position for calculating with basic tactics. It's easy enough to get the R sac reload idea, but seeing that it obstructs the initial mate net and requires an additional move for a discovered checkmate is not trivial calculation for most beginners imo. |
|
| Jul-24-17 | | King Harvest: Such a nice teaching position it taught me! There's a second way mate! Lol@self |

 | | takchess: going to try to do a complete week of puzzles and giving it sufficient time.
Here's my answer for today.
37...Rb2+
if 38 NXb2 Rxb2 +
39 Kf1 Nb3 ++
if 38 Kf1 Rxc2 discover check
some blocks by white that don't hold up and mate. |
|
| Jul-24-17 | | beenthere240: 39. K f1 is brilliant. The flying king! |
