| Feb-08-16 | | lost in space: I love Mondays, especially Rose Mondays (Lunar New year) with such amusing puzzles. 29...Qg2+! 30. Rxg2 (only move) 31. Rf1+ Qxf1 32. Rf1# Nice! |

| Feb-08-16 | | dfcx: Game was about even until 22.Rd2. White should play 22.Rxf8 Rxf8 23.exd5! Qxd4 24.Qxe6+ Kd8 25.Qd6+ and draws

| Feb-08-16 | | agb2002: Black is one pawn up.
White threatens 30.Nxe4 and 30.Nxf7.
The rook on f2 stops 29... Rf1+ 30.Qxf1 Rxf1#. Hence, 29... Qg2+ 30.Rxg2 Rf1+ and mate next. |

 | | gawain: Chessgames keeps coming up with interesting Monday puzzles. The black knight is fantastically placed. 29...Qg2+ 30 Rxg2(forced) Rf1+ 31 Qxf1 Rf1# |
|
| Feb-08-16 | | patzer2: This is a first for me. After easily solving a Sunday puzzle, I missed the easy mate-in-three solution 29...Qg2+ 30. Rxg2 Rf1+ 31. Qxf1 Rxf1# to today's Monday puzzle. Figured it was easy, so I went for the first move that came to mind with 29...Rxf2 expecting 30. Qxf2? Rxf2 31. Rxf2 (31. Nxe4 Rf1#; 31. Kxf2 Qg2+ 32. Ke1 Qf1#) 31...Qg4  (-22.82 @ 22 depth, Deep Fritz 15). What I missed after 29...Rxf2 was 30. Qa6+! when the win is much more difficult after 30...Qb7! 31. Qxb7+ Kxb7 32. Rxf2 Rxf2 33. Kxf2 Nxc2 34. Nf7 (-2.47 @ 25 depth, Deep Fritz 15). As <dfcx> observes, instead of 22. Rd2? allowing 22...d4!  (-0.96 @ 21 depth, Deep Fritz 15), White should have played 22. Rxf8 Rxf8 23. exd5! = (0.00 @ 20 depth, Deep Fritz 15). P.S.: I suppose my try 29...Rxf2! technically wins, and therefore might be considered an alternate solution. However, because it makes the win so much more difficult, I'm counting it as a miss. |

| Feb-08-16 | | patzer2: Though the mate-in-three combination 29...Qg2+ 30. Rxg2 Rf1+ 31. Qxf1 Rxf1# is simple to comprehend, especially after seeing the pattern, it intertwines several tactical themes. For example, 29...Qg2+! is a sham Queen sacrifice which clears the f file and simultaneously deflects the Rook from f2 to g2. The next move 30...Rf1+ is a sham Rook sacrfice which decoys the Queen from e2 to f1, which in turn allows the mate 31...Rxf1#. In any event, it's an entertaining and instructive tactic. |

| Feb-08-16 | | saturn2: I saw this one (Qg2 followed by rook/knight mate on the backrank)quickly. |
|
| Feb-08-16 | | mel gibson: I saw it in 3 seconds.
Good one. |
|
| Feb-08-16 | | whiteshark: <29...Qg2+!!> and take it like a man, Mann. |
|
| Feb-08-16 | | schachfuchs: Is 30...Rf1+ really a Rook sacrifice?! |
|
| Feb-08-16 | | CHESSTTCAMPS: Black is up a pawn with a winning attack, thanks to the the aggressive battery of rooks controlling the f-file combined with the ideally posted queen and knight. White threatens 30.Nxe4 and black has a terrible blunder to avoid: 29... Rxf2?? (intending 30.Nxe4 Rf1+) 30.Qa6+! Kb8?? (Qb7) 31.Rxf2! and now white's double threat of Rxf8+ and Nxe4 wins for white. Instead black forces mate with 29... Qg2+! 30.Rxg2 Rf1+, observing the traditional Monday queen sac, in a puzzle where there is a particularly heavy penalty for plausible, non-forcing moves. |
|
| Feb-08-16 | | Once: The Rf2 is overworked. It has to guard against Qg2# and the rook reloader Rf1+/Qxf1/Rxf1#. So deflect the rook by one of the mates and then kill him with the other. Happy mondays. |
|
| Feb-08-16 | | morfishine: White must've felt like a real Schlep. Mann up!
<Whiteshark> Black won ***** |
|
| Feb-08-16 | | whiteshark: He that makes himself a Shep, shall be eaten by the Mann. |
|
| Feb-08-16 | | Cheapo by the Dozen: Sort of Bobby Fischer Teaches Chess (but if so then surely toward the end of same). |
|
| Feb-08-16 | | kevin86: The major pieces on the second row are lined as a convoy. Sadly, the queen sac dislodges one and allows a mate behind them. |
|
| Feb-08-16 | | stst: missed the boring insane, get to Q-sac Mon again...
Q & N have excellent spot on g2, so
29...........Qg2+
30.RxQ Rf1+
31.QxR RxQ# supported by N |
|
| Feb-08-16 | | stst: <Hope Superbowl Sunday was great for everyone. Happy Lunar New Year!> Thanks Sir (or Mam, maybe!!)
Try to opt for the underdog in the XV game, but the QB for pants was a great disappointment!! - They lost the game, not because of the opponent, but, alas, of themselves!! |

| Feb-08-16 | | Nullifidian: 29... ♕g2+ 30. ♖xg2 ♖f1+ 31. ♕xf1 ♖xf1# |

| Feb-08-16 | | hoodrobin: Hey <chris>, keep going! |
|
| Feb-08-16 | | waustad: Knowing it is a Monday puzzle I got it quickly. I wonder if I'd have done so without that extra hint. |
|
| Feb-09-16 | | patzer2: <schachfuchs: Is 30...Rf1+ really a Rook sacrifice?!> No, that's why I called it a <sham sacrifice.> The term "sham sacrifice" (a.k.a. "pseudo sacrifice" or "temporary sacrifice") refers back to the terminology used by Rudolf Speilman in his classic work "The Art of Sacrifice in Chess." Speilman's explanation of sham (temporary) sacrifices can be found by clicking on the free "look inside" feature, advertising the book, at http://www.amazon.com/gp/product/B0... where Speilman classifies sham (temoporary) sacrifices into three categories: 1. Positional sacrfices
2. sacrifices for gain
3. mating sacrifices
I could be wrong but I think 30...Rf1+, decoying or forcing the Queen to f1 to allow mate, fits the category of a sham (temporary) sacrifice of a Rook to force mate. |
|
| Feb-10-16 | | patzer2: <Once> I very much like your straight forward and incisive description of this week's Monday solution/combination as exploiting the "overworked Rook" on f2 with a dual mate thread. I'll definitely use it as an example of the "over-worked piece tactic" in teaching my grandsons. |
