Black can deliver mate with 29... Qxg1+ 30.Kxg1 Rf1#. |

 | | al wazir: OK, I'll bite. What happens after 27. Rxa8 ?
My answer is 27....Bh3 28. Qc2 (forced) Qf1+ 29. Rg1 (forced) Rf2! 30. Ne2!! Bg2#!!! Is there something wrong with my analysis, aside from the superfluous parentheses and exclamation points? Did Paulsen really see all this OTB? Did von Schmidt (whoever he was) also see it, and is that why he didn't take the proffered ♖? |
|
| Feb-29-16 | | Boerboel Guy: Of course he saw this over the board!
Not too difficult at all, for such a fine player! |

My answer is 27....Bh3 28. Qc2 (forced) Qf1+ 29. Rg1 (forced) Rf2! 30. Ne2!! Bg2#!!! Is there something wrong with my analysis, aside from the superfluous parentheses and exclamation points? Did Paulsen really see all this OTB? Did von Schmidt (whoever he was) also see it, and is that why he didn't take the proffered ♖?> How about as in the game ... 27....Bh3 28. Qc2 (forced) Qf1+ 29. Rg1 (forced) Qxg1 30. Kxg1 Rf1#!!! |

| Feb-29-16 | | Tiggler: <Penguincw: Leonardo DiCaprio wins the Oscar!> Did it occur to you that those who did not know that did not wish to know that? |
|
| Feb-29-16 | | saturn2: Mate in 2. White had the bishop pair at move 16, at the end black had an active bishop supporting mate. Instead of the suicidal 16 g4 Be2 seems better. |
|
| Feb-29-16 | | morfishine: <29...Qxg1+> and mate next move |
|
| Feb-29-16 | | stacase:
Wham Bam! |

| Feb-29-16 | | zb2cr: Quite simple. 29. ... Qxg1+; 30. Kxg1, Rf1#. |

| Feb-29-16 | | whiteshark: Rock my ♖, Louis! |

| Feb-29-16 | | YetAnotherAmateur: I love queen sac Mondays! 29. ... Qxg1+ 30. Kxg1 (forced) Rf1# and that's all she wrote. |

 | | PawnSac: < agb2002: Black has a bishop and two pawns for a knight.
Black can deliver mate with 29... Qxg1+ 30.Kxg1 Rf1#. > Strange.
I looked at the board, saw the mate in seconds, then entered the room to see comments. I never even considered counting material. The only relevant material is..
click for larger viewthe tactical considerations..
white has a weak back rank and only the K can capture on g1.
everything else is irrelevant. |

| Feb-29-16 | | BOSTER: <al wazir : 29...Rf2 30. Ne2>.
30. Qxf2 Qxf2 and no Oscar to you.
Better was 27.Re1. |
|
| Feb-29-16 | | TheTamale: White really dropped the ball with 24) Qb3. It was like an invitation to overrun his position. Plus the queen does nothing on that square. Hard to see what the motivation was. |

 | | patzer2: Three of my Grandsons were visiting, so I let the two older boys take a shot at solving the Monday puzzle. Both the 9-year-old and the 7-year-old found the 29...Qxg1+ 30. Kxg1 Rf1# solution. I showed them the combination starts with at least a mate-in-three with 28...Qf1+, which was set up one move earlier with 27...Bh3! The five-year-old is using an apple application on his Mom and Dad's IPAD to help learn the moves and the rules, and is not quite ready for tactics puzzles just yet. The older boys have been studying tactics on the computer and out of junior level tactics books, so they have a leg up on most elementary age students when looking at a simple tactics puzzles. Analyzing the game with Deep Fritz 15 and the Chessgames.com opening explorer, it turns out Paulsen played very accurately with the Black pieces, even by modern Super GM and modern Chess program standards. White's clearly decisive mistake was <24. Qb3??> allowing the game reply 24...Qxg4  (-3.80 @ 19 depth, Deep Fritz 15) or the computer choice 24...Bxf5 (-5.51 @ 17 depth, Houdini 4). Instead of <24. Qb3??>, 24. Qe2 maximizes resistance as play might continue 24...hxg4 25. Rf1 b6 26. Kg2 Rxf5 27.
Rxf5 Qxf5 28. Qe7 Qf3+ 29. Kg1 g3 30. Qh4+ Kg6 31. Qxg3+ Qxg3+ 32. hxg3 Kf6 33. d4 Bb7 34. Re3 Rc8  (-1.29 @ 21 depth, Deep Fritz 15) with practical drawing chances. For possible opening improvements, I prefer the popular move 4. O-O
as in M Vachier-Lagrave vs L Bruzon Batista, 2016 and 11. Re1 as in V Gashimov vs Eljanov, 2008. Black's game seems to take a turn for the worse with 13. Bd2?! allowing 13...c6  (-0.35 @ 19 depth, Deep Fritz 15). Instead I prefer 13. Bc1 when play might continue 13...c6 14. Bd3 Nc5 15. Bxf5 Bxf5 16. Be3 Qe7 17. Nd2 Na4 18. Rb1 Rad8 19. Nf3 c5 20. Bf2 d4 21. Nh4 Bd7 22. Qd3 Qe6 = (-0.12 @ 18 depth, Deep Fritz 15). |

| Feb-29-16 | | JimNorCal: patzer2 is my favorite commenter.
For his skeptical and lucid analysis. And for the occasional wonderful stories like this one about his grandkids. |

| Feb-29-16 | | BOSTER: < TheTamele: 24 Qb3 hard to see what the motivation was>.
The idea was very nice , to move white queen to g8, but he forgot to play 24.Ne4 in between.
This is the pos white to play 24.

After 24.Ne4 dxe4 25. Qb3 |

 | | gawain: It's Monday? And a rook is on the same file as his queen? Blast away! 29...Qxg1+ Kxg1 30 Rf1# |
|
Feb-29-16
 | | Bubo bubo: I hoped for something special on February 29, but to no avail: 29...Qxg1+ 30.Kxg1 Rf1# (At least the puzzle asks for Black's 29th move!) |
|
| Feb-29-16 | | dark.horse: Easy for a Monday :) |
