|
| Nov-27-14 | | diagonalley: one has to admire black's tenacity in fighting back to draw! |

| Nov-27-14 | | wooden nickel: This game is interesting in many ways, after White's move 20. Be4, the variation
20. ... Bxe4 21. Rxd7 and White is winning!
click for larger view
21. ... g5 (Rxd7? is worse 22. Nf6+ Kg7 23. Nxd7 forking the Black's queen and rook while the bishop is still hanging).
Also the ending with R+2P vs R, demonstrates the difficulty of such positions.
Nice Thursday puzzle! |

| Nov-27-14 | | sfm: Right now I am looking at 25.Bf5... |
|
| Nov-27-14 | | morfishine: Thanksgiving morning is one of my least favorite times to
engage in exhausting mental chess exercises. I much prefer
to focus on filling the house with the pleasing aroma emanating from
a slow roasting bird. Soothing classical music meanders quietly in
the background. Pressing thoughts melt away
In this environment, at least for me, chess satisfaction is arrived at
through the intuitive sense and seeing if that 'hunch' is at least fairly
close to what was played or should've been played... As a base line I had <22.Nxf7> with the idea that 22...Kxf7
23.Qxh7+ just can't be good for Black
So I figured best for Black was 22...Rxf7 23.Qxd8 (White has won
an exchange not fearing Black's threat against f2: 23...Qxf2+ 24.Kh1 Qc5)
click for larger viewThats it for me, I hope you all have an enjoyable Holiday season! ***** |

| Nov-27-14 | | eblunt: Instead of the game 24. ♖d5, I had 24 ♕xg6+ ♔e7 25. ♗d5 as per <agb2002> I don't see how black stops the check on e6 without losing a lot of material |
|
| Nov-27-14 | | sfm: So,
25.Bf5,gxB
26.Qh6+,Kf7
27.Qxe6+,Kg7
28.Qe7,Rf7
29.Qg5+,Kf8
30.Rh5
White threatens Rh8 mate, to which there is no proper defense.
Other Black alternatives are not better.
I am approx. 50% sure about the two above statements. |
|
| Nov-27-14 | | sfm: OK, I cheated. 30.Rh5 is not possible. But... |

 | | scormus: cg, THANKS for GIVING us the turkey ;) |
|
| Nov-27-14 | | awfulhangover: Silly! I mean, taking the knight with the king is just too silly to be true. Much, much better is taking with the rook, and the comps agree with my patzer brain. How could white not win this? |
|
| Nov-27-14 | | abuzic: <Dr. J: You have provided 6 strong alternative continuations for White, but I'm not yet convinced any of them is a forced win: e.g., at (*) Black has 33...Rd6 (34.Re7+ Rd7 35.Rxd7+ Kxd7 36.b4 (36.Bxb7?? Qxf2+) Ra8 37.Qxb6 Bxf3) and at (**) and (***) Black has 30 (or 31)...Qc5. Can you provide more analysis to finish this off? By the way, what do you think of my earlier suggestion (after 28.Rxe6+ Kc7 29.Re4 Qf7) 30.Qh4?> At (*) 33...Rd6 34.Re7+ Rd7 <35.♖7e5!> (to be followed by ♖xc5+), if 35...♔c8 36.♕xb6 ♘e4 37.♖1xe4 ♗xe4 38.♖c5+ ♖c7 39.♗g4+ ♖f5 a. <39...Kd8 40.Qb8+ Ke7 41.Rxc7+ Qxc7 <(41...Kf6 or 41...Kd6 lead to mate comb after 42.Qb6+)> 42.Qxc7+ wins>; b. <39...Bf5 40.g3 Qc1+ 41.Kg2 Rxc5 42.Qxc5+ Kd7 <42...Kb7 43.Bf3+ Kb8 44.Qxf8+> 43.Bxf5+ Rxf5 <(43...Ke8 44.Qe5+; or 43...Kd8 44.Qd6+ both lead to forced mate)> 44.Qxf5+ wins> 40.♖xc7+ ♕xc7 <40...Kd8 41.Qb8#> 41. ♕e6+ ♔d8 <41...Qd7 42.Qxe4> 42.♗xf5 ♗xf5 43.♕xf5 a clear winning position for white. At (**) <30...Qc5> or at (***) <31...Qc5)> 30. (or 31).♖c4 and black loses the Q, if this leaves the a3-f8 diagonal then ♕d6#. For the suggestion <30.Qh4> 30...Bb7, black at least got away from white's strong attack after white's 28.Rxe6+. One of the alternative suggestions to 25.Rg5:
25.♗c2 ♕c6 26.♖g5 ♖g8 27.♕h4 ♔f7 28.♗xg6+ ♖xg6 29.♕h7+ ♔e8 30.♕xg6+ ♔e7 31.♕g7+ ♔d6 32.♖xe6+ ♔c7 <32...Kxe6 33.Rg6+ Kf5 <(33...Kd5 34.Qd4#)> 34.g4+ Kf4 35.Qh6+ Ke5 36.Qg5+ Ke4 37.Qf5#> 33.♖xc6+ wins |
|
| Nov-27-14 | | TheaN: Thursday 27/11 <22.?> Material is even, white is ferociously aiming at the black kingside whilst the center is under control by the rooks. The off-position of the knight on h6 suggests <22.Nxf7>. Upon immediate inspection, black's surrender of material does not do well at all, after 22....Rxf7? 23.Qxd8 Qxf2+ 24.Kh1 it is white in control, not black. This is also the easy way out for white. Instead, <22....Kxf7 23.Qxh7+ Kf6> puts up a lot more fight and more resistance to the sacrifice. In fact, I opted for <24.Qxg6+?! Ke7 25.Bd5? Qxf2+ 26.Kh1 Nf6!<>> defending e6 and Black is much better. White's text move <25.Rd5!> is amazingly strong. I had visioned this move as not working on move 26 and therefore discarded it, but once again turning the moves around works. Sadly, White falls into his own traps after <25....Qc7 26.Rg5?!  > and the attack becomes much less potent. Instead, <26.Qh4+!> gives black enough headaches to work with and it's forced to boot (26.Bc2 involves the same idea). All variations on 26.Qxh4+ give white a mate or enormous material advantage: the point is that white will sacrifice on g6, opening up the file for the rook. The major pieces will decide the game. The most prominent line after <26.Qh4+> is <26....Kg7 27.Bxg6! Nf6! (defend h7) 28.Rg5 (threatening Be8#) Rd5! (the only proper way to attack the mating piece) 29.Rg3!!  > keeps the discovered check intact and white will start to win loads of material (black is basically forced to take on g3 at one point). Do mind that in this variation, the last three moves from white are the only moves that keep up a +4 advantage, so he has to vision all of this. Regardless, white's premature Rg5 eventually drew him the game so he should have put more thought in his 26th move. |
|
| Nov-27-14 | | TheaN: Whoops, in my main post all moves from 25.Rd5 are one move earlier. Don't know where I made the miscalculation. |
|
Nov-27-14
 | | fm avari viraf: Yes, even I feel Mr."An Englishman" that 24.Rd5 is more spectacular. |

| Nov-27-14 | | TheBish: N Delgado Ramirez vs A H Wohl, 2001 White to play (22.?) "Medium", even material.
The dark squares surrounding Black's king (f6 and h6) are somewhat weak, but that is not the target of White's attack. 22. Nxf7! Kxf7
If instead 22...Rxf7, White has 23. Qxd8. Also losing is 22...Rde8 23. Nd6 Rd8 24. Qe7+ Kh8 25. Qxe6 with two pawns and a dominating position. 23. Qxh7+ Kf6
A quicker loss is 23...Ke8 24. Bxg6+ Rf7 25. Qxf7#.
At this point the knockout punch was hard to find. (Could easily have been a "difficult" puzzle.) After the natural 24. Qxg6+ Ke7, Black is threatening 25...Qxf2+ and also is able to defend. The key is delaying this capture and instead bringing another attacker into the game with tempo. 24. Rd5!! Qc4
Or 24...exd5 25. Qxg6+ Ke7 (25...Ke5 26. Bd3+ mates) 26. Bf5+ with a forced mate in 3: 26...Qe3 27. Rxe3+ Ne5 28. Rxe5+ Be6 29. Qxe6#. Also if 24...Qc7, 25. Rd3! e5 26. Bd5 and the noose tightens. 25. Rd4 Qc7 26. Bc2! e5
click for larger view 27. Rf4+! Ke6
As Black is mated after 27...exf4 28. Qxg6#.
28. Bb3+ Kd6 29. Qxg6+ (finally!) Nf6 (or 29...Kc5 30. Rc4+) 30. Rxf6+ and Black is down three pawns with White's attack raging on. |

| Nov-28-14 | | patzer2: Solving yesterday's Thanksgiving puzzle (22. ?) is like attempting to eat a whole turkey without help -- a task easy to start but hard to finish. Here's a look with Fritz 12:
<22. Nxf7! Kxf7> This is the easy and obvious beginning. if 22...Rxf7?, then 23. Qxd8  .
<23. Qxh7+ Kf6>
If 23...Ke8??, then 24. Bxg6+ Rf7 25. Qxf7#.
<24. Rd5!!> This surprise move is best, but it's also where the puzzle gets complicated. <24...Qc7>
If 24... exd5?, then 25. Qxg6+ Ke7 26. Bf5+ Ne5 27. Rxe5+ Be6 28. Qxe6#. <25. Rg5> This should win, but Fritz 12 finds several stronger, winning alternative moves. Best is 25.Bc2!! when play might continue 25...Rg8 (25... exd5?? 26. Qxg6#) 26. Rg5 Kxg5 27. Rxe6 Nf6 28. h4+ Kg4 29. f3+ Kg3 30. Qxc7+ Kxh4 31. Qf4+ Kh5 32. g4+ Kh4 33. Re2 Rd1+ 34. Bxd1 Nxg4 35. Rh2#. Also strong is 25. Rd3!! when play might continue 25...Qf4 26. g3 Qg4 27. Rf3+ Ke5 (27... Kg5 28. Qxg6#) 28. Qe7 Nf6 29. Bb7+ Ne4 30. Qc7+ Rd6 31. Qg7+ Rf6 32. Qxf6#. <25... Qf4! 26. Rxg6+ Ke5 27. Bf3+ Kd6 28. Rgxe6+?!> White's winning chances are diminished after this tempting but less than "best" move. Instead, 28. Rg4! keeps the win intact when play could continue 28...Qf5 29. Rd1+ Kc7 30. Qe7 Qe5 31. Re4 Rde8 32. Qxd7+ Bxd7 33. Rxe5 . <28... Kc7 29. R6e4 Qf7 30. Qxf7 Rxf7 31. h4 Kb8 32. Re8 Rxe8 33. Rxe8 Nf6 34. Rd8 Kc7 35. Rd4 Be6 36. b3 Nd7 37. Bd5 Nc5 38. Bxe6 Nxe6 39.

Rxg7> It's really complex here. According to the online shredder endgame table base, Black must play 77...Re1! = to force the draw. <77...Kd8?!> According to the shredder table base, Black now loses in 39 moves. However, as this game shows it's not so easy for White to find the win. <78. Ke5 Rd1 79. Rg4 Kc7 80. Rd4 Rh1 81. Rd3 Kc6 82. Kd4 Rc1 83. Rh3 Rd1+ 84. Kc3 Rb1 85. Rh6+ Kc5 86. Rh5+ Kc6 87. a4 Rc1+ 88. Kd3 Ra1 89. a5 Rc1 90. Rg5 Rd1+ 91. Kc2 Ra1 92. Kb2 Ra4 93. Kc3 Ra1> At 31 depth Fritz 12 indicates White has a winning +3.86 advantage. However, the 6 piece shredder table base correctly indicates it's a draw. <94. a6 Kb6 95. Rg2 Rxa6 96. Rg6+ Kc5 1/2-1/2> |
