| Nov-23-13 | | mistreaver: Saturday. White to play. Very difficult. 25?
On very first glance i wanted to take on f6.
25 Rxf6 Kxf6 (what else, 25... Rb8 26 Qd4 Qxb2+ 27 Kd2 is good for white i think.)
and now i was calculating both Rf1+ and Qd4+ and i couldn't find promising continuation with king on g8
Say:
26 Qd4+ Kf7
27 Rf1+ Kg8
28 Qf6 Rf8
29 Qe6+ Kg7
30 Be5+
and now:
A)
30... Kh6
31 Qh3+ Kg5
32 Qg3+ and the most i can achieve is perpetual
B)
30... Kh6
31 Rh1+ (maybe this is stronger)
31 ... Kg5
32 Bxh8 or something
C)
30... Nxe5
31 Qxe5+ Kg6
and i don't see a quick mate here.
Time to check and see how it really went. I am positive i got the first move right, but i don't know about the most ocrrect follow - up.
---
Wow, i was closer then i could have expected. Altough the game move 28 Ne4 sure is attractive, my line wins faster;
after
25 Rxf6 Kxf6
26 Qd4+ Kf7
27 Rf1+ Kg8
28 Qf6 Rf8
29 Qe6+ Kg7
30 Be5+ Nxe5
31 Qxe5+ Kg6
There is mate in 2
32 Qg3+ K-h line
33 Rh1 mate
it also happens if white refuses the bishop:
30... Kh6
31 Qh3 Kg5
32 Qg3+ Kh6
33 Rh1 mate.
After Qf6 Fritz indicates mate in ten.
And also after other moves black king is too open to doo anything about it's life.
Too bad i wasn't precise enough till the end, i can't claim full credit now :( |

| Nov-23-13 | | goodevans: The first move was very easy to predict. Everything else rather less so. |
|
| Nov-23-13 | | gofer: Given the position of black's pieces it is obvious that Ra8, Rh8 and Qb7 are
going to struggle to help the black king if their help is needed. So our plan
is simple. Make then need to come to the black king's defense and exploit
their poor placement...
<25 Rxf6 Kxf6>
<26 Rf1+ ...>
I think on principle, it is best to get the least mobile piece into the
attack first and controlling the f file will severely limit black's
choices. This has the added benefit of allowing Rf7+ and Rxc7+ if the
black king tries to run to "safety" via c8...
27 ... Kg8
28 Qf6 Rf8
29 Qe6+ Kg7
30 Be5+ mating
27 ... Kg5
28 Qf5+ Kh6
29 Qf6 mating
27 ... Ke6
28 Qf5+ Kd7
29 Rd1+ Kd8
30 Bh4+! Nxh4
31 Qf6+ mating
<26 ... Ke7>
<27 Qe3+ Kd7>
<28 Rf7+ Kc8>
<29 Rxc7+ Qxc7>
<30 Bxc7 Kxc7>
<31 Qc5 ...>
Now I can't claim that this last line is a win, or even the best option
but it seems okay!

What do our silicon friends say about the best attack after <26 ... Ke7>? |
|
| Nov-23-13 | | abuzic: 25.Rxf6 Kxf6
26.Qd4+
this is much stornger than Rf1+ contrary to what seems obvious, cause this allows the king to safer post like this:
26.Rf1+ Ke7 27.Qe2+
<27.Qe3+ Kd8 28.Rf7 Re8 29.Bh4+ Nxh4 30.Qg4 Nf5 31.Qxf5 leads to same position; and if 27.Re1+? Kd8 no more attacking ideas)> 2...Kd8 28.Rf7 Re8 29.Bh4+ Nxh4 30.Qh3 Nf5 31.Qxf5 Re7

White will emerge a piece up after 32.Qf6 Qb4 33.Rf8+ Kd7 34.Rxa8. Even a second sac 26.Ne4+ is stronger than Rf1+:
26.Ne4+ Ke7 <26...dxe4 27.Rf1+ and the king siege is complete: 27...Ke7 28.Bh4+ Nxh4 29.Qxe4+ forces win.> 27.Qd4 Kd8 28.Nc5 Qa7 <(28...Qb6 29.Bh4+ Kc8 <29...Nxh4 30.Qf6+ Ke8 31.Re1#)> 30.Qg4+ Kb8 31.Nd7+ wins the Q> 29.Qf6+ Kc8 30.Qxc6 very strong mating attack |

| Nov-23-13 | | abuzic: <gofer:
25 Rxf6 Kxf6
26 Rf1+ ...
26 ... Ke7
27 Qe3+ Kd7 <27...Kd8 is safer>28 Rf7+ Kc8
29 Rxc7+?>
I don't know if silicon is needed to find this does not work. 29 Nb5, Nd5, or Qe6+ should win:
29.Nb5 cxb5 30.Qe6+ Kb3 31.Rxc7 |

 | | Penguincw: 25.Rxf6 seems logical enough, removing a defender of the black king and also a potential attacker of the white king. |
|
| Nov-23-13 | | kevin86: White gives up exchange-to open the game against the black king. |
|
| Nov-23-13 | | patzer2: Got the obvious 25. Rxf6+!! Kxf6 , but was unsure as to whether 26. Qd4+ or 26. Rf1+ was the winning follow-up. Plugged it into Fritz 12 on my laptop (dual core running @ 2.1 GHz) and it turns out both 26. Qd4+ (+15.97 @ 20 depth) and 26. Rf1+ (+3.74 @ 20 depth) win. The computer evaluation appears to confirm <abuzic>'s assertion 26. Qd4+ is "much stronger." However, I chose the weaker winning alternative 26. Rf1+ and after 26...Kg7 27. Qd4+ Kg8 chose 28. Qf6! (instead of the clever but more difficult 28. Ne4!). After 28. Qf6! Rf8 (diagram below),

| Nov-23-13 | | patzer2: <gofer> <What do our silicon friends say about the best attack after <26 ... Ke7>?> Pretty much what <abuzic> posted about 26. Rf1+ Ke7. |

 | | FSR: 25.Rxf6 Kxf6 26.Qd4+ followed by a rook check and doubling queen and rook on the seventh rank or, in the case of 26...Kg5, 27.Rf1. The king ain't coming back from this road trip. |

Sometimes timid Samisch played sharp Ne7x and mate in 4. |
|
| Nov-23-13 | | Shams: <BOSTER> Great finishing tactic; what game is it from? Also, I count mate in five if Black takes the rook. :) |
|
| Nov-23-13 | | Moszkowski012273: Pretty poor moves at the end from both sides. |
|
| Nov-23-13 | | Patriot: 25.Rxf6 looks interesting. 25...Kxf6 26.Qd4+ Ke7 27.Re1+ Kd8 28.Qf6+ Kc8 is a bit hard to quantify. But there are plenty of other candidates to try. 28.Bh4+ Kc8 29.Qg4+ Kb8 and I'm not sure what that does. I need a way to get the most pieces in the attack so 26.Bh4+ makes a lot of sense. 26...Nxh4 27.Qd4+ Kg6 28.Qg4+ seems like a very fast way to get each piece in the attack while taking the knight out of it's defensive role. There's so much more to this but this seems like a very strong attack. |
|
| Nov-23-13 | | BOSTER: < Shams > Game Samisch vs J Engel, 1928y. |
|
| Nov-23-13 | | parisattack: Alekhine did well with the Modern Steinitz - won some lovely games. But offhand I can't think of any other master who was particularly fond of it. 5. 0-0 seems most popular now with White doing quite well. I guess Fischer was on to something when he played it against Geller. |
|
| Nov-24-13 | | patzer2: <Shams> I suppose the mate-in-four solution to the diagram in <BOSTER>'s post is 24. Ne7+! Qxe7 25. Rh8+ Kf7 26. Bg6+ Kxg6 27. Qh5# from Saemisch vs J Engel, 1928. |
|
| Feb-13-21 | | Scuvy: I believe Paul Keres was the modern master who used the Modern Steinitz the most, attaining an excellent lifetime record with it. Tim Taylor, in his book "Slay the Spanish!," claims a 70+ percent success rate for Keres. |

| May-01-22 | | whiteshark: This chess performance is like a 9 on the Richter scale |
