 | | FSR: <centralfiles> Thanks, I will have to check that out. I have a little familiarity with that line. Many years ago (c. 1977) I was Black in a game against Alan Kobernat where I played 10...Ne6 11.f4 a6?? (Of course, I saw the refutation a second after I played the move.) 12.f5! and I was crushed much as in V Kirilov vs F Salata, 1964. But after 11...g6! maybe Black is OK!? Note that 10...e5!? 11.Nc7+ Kd7 12.Nxa8 Bb4+ 13.Kd1 Ne7, staying an exchange down, has been played, notably by Topalov. Opening Explorer |

 | | Phony Benoni: I have a friend who is going through the <Illinois Chess Bulletin>, and has noticed events held in both <Forest Park, IL> and <Park Forest, IL>.. On Wikipedia, I see that tese are two separate villages, both suburbs of Chicago. Forest Park (pop. 15,000) is somewhat to the west of the city, while Park Forest (pop. 22,000) is to the South and seemingly further away.. Since both were associated with Chicago, I was wondering if you knew whether there has been chess activities in just one or in both communities. Thanks for your help. I understand this may be too general of a question for a definitive answer. |

Played today in the above line. Nice showcase of just how bad things can get for black. |
|
| Jan-12-20 | | centralfiles: <FSR> i was searching in vain for Kirilov's games yesterday. It seems i had the wrong Kirilov. As far as 11...g6 
click for larger view
Chandler gives
12.Bg2 O-O-O
13.Be3 a6
And after some more moves white has large plus, but 12...O-O-O looks very suspect. |
|
| Jan-12-20 | | centralfiles: What I find really ironic here is this <Quotes from Chandler> <"10...Nc2+
Eco doesn't even bother to mention this knight fork! Alternatives have long been known to favor White: a) 10...Ne6 11.f4! a6......
b)10...e5 11.Nc7+ Kd7 12.Nxa8 Bb4+ 13.Kd1.....
c)10...O-O-O 11.Nxd4 Rxd4 12.Be3 Rd7<...Rd6 is much better try-CF> 13.Bb5........> If your ideas above hold up these lines are actually better than the knight fork Chandler puts all his focus on. |

| Jan-12-20 | | centralfiles: Some analysis on the theory of a quite common c3 sicillian sideline. Part Two.
This is my own analysis <i.e. analyzed on my own engine ;) > with improvements for white in both of the "equalizing" variations Chandler gave <above> in the 10...Nc2+ lines. Lets start with "A)"
Chandler's analysis<not given in full> <"10...Nc2+
11.Kd1
A) 11...Nxa8
12.Nc7+ Kd2
13.Nxa8 g6
14.Be3 Bh6!
A1)
15.Bb5+ Kd6
16.Bxa7 Nf6
17.Nb6 Rd8
18.Ke2 Nc2
19.Rd1+ Kc7
20.Rxd8 is an equal ending
or A2)
15.Bxa7 Nf6
16.Nb6+ Kc7
17.Bd3 Rd8
18.Ke2 Nc2! with the knight escaping black is more than ok."> Black aims for a simple setup with Kc7 Rd8 and bishop covering the c1/d2 squares but white can disrupt this with 15.Bb5+ Kd6
16.Bxa7 Nf6
17.Nb6 Rd8
18.Ke2 Nc2
19.Nc4+!<or 18.Nc4+ is the same>
click for larger view
And Black is forced to play the ugly
19...Ke6
20.Rd1 Nd5
21.Be3 and the lack of harmony in the black camp is telling.
<Stockfish about +1.2> |
|
| Jan-12-20 | | centralfiles: Much more interesting and rewarding however is 17...Kc7 
click for larger view
This is not mentioned by Chandler, which makes sense as it will just transpose into his main line <18.Ke2 Nc2 19.Rd1 Rd8 as in A1> which equalizes. Can White improve here?
This is not so simple at first <or 2nd or 3rd...> glance.
i.e. 18.Nc4 Nd5 19.Be3 Nxe3 20.fxe3 Ra8 peters out to = after a couple moves. White does have a really nice idea which I'll wait a few days before posting since it seems worth the effort. <Disclaimer: this poster assumes no responsibility if you find it obvious, for me it was a total surprise in a simple position> |

Jan-13-20
| | FSR: Those bishops on an open board are scary. I never played that line again after my debacle - although it seems that it is in fact playable. I usually play 2...Nf6, which I think is a little better than 2...d5. |

| | FSR: <Phony Benoni> Yes, I believe there have been chess events in both Park Forest and Forest Park, as your friend's researches suggest. For example, my most famous game, F Rhine vs D Sprenkle, 1981, was played in Forest Park. |
|
| Jan-13-20 | | centralfiles: The Delchev game is really a beauty.
Thanks for uploading it. |

A closer look at the 2nd of chandler's "equalizing" lines above that i fear has become standard book fare.

10...Nc2+
11.Kd1 Rc8!?

13.b4 Nxb4
14.Bb5+ Kd8
15.Be3
here 15...e6! with the eventual exchange sacrifice is indeed very solid. <Even 14.Be3 e6! 15.Bxc5 Bxc5 leaves black with plenty of compensation> For some reason all have assumed the immediate 14.Bb5+ as being necessary here it ain't so. 14.Rb1!TN

| Jan-13-20 | | centralfiles: "It may be that improvements are found which allow black to hold the draw with precise play. Nevertheless we can certainly say that the position after 10...Nc2+ leaves white with a dangerous initiative..." |
|
| Jan-14-20 | | centralfiles: I'll wait awhile before giving solution to the
A1)17...Kc7 problem i posted earlier in case you want to try solving it.

| | FSR: I predict that in 2024 Firouzja will dethrone Ding Liren as classical world champion. You read it here first. |
|
| Jan-16-20 | | centralfiles: Since both of these 10...Nc2+ lines are actually played sometimes I finally checked chesstempo<I don't have access to chessbase etc.> to see what a database might say of my improvements. In the first line
11.Kd1 Nxa1
12.Nc7+ Kd7
13.Nxa8 g6
There were ZERO games where my 19.Nc4 was played, instead they all played the meh 19.Rd1 which doesn't get White anything. In the 2nd line
11.Kd1 Rc8
12.Nxa7 Rc5
13.b4 Nxb4
There was one game where 14.Rb1! was played.
https://chesstempo.com/gamedb/game/... This game follows a path I didn't bother to investigate above. After seeing this game I definitely should have. 14.Rb1

Up until now wer'e seeing perfect play by White<and Black> nearly all White's moves are the only moves that win. But now
23.Rxd7? <I would probably play this myself :(> And POOF White is left with nothing and was actually very lucky to survive with a draw. The simple
23.Bxd7+ Kd8
24.Rxb4 Kxd7
25.Rxf4
click for larger view
is easily winning. I hope martin was able to sleep that night... As far as the the 17...Kc7 idea in the first line above <See DIAGRAM> there was actually no games where Black tried this- a shame because solution<still not posted> is nice.

18.f4! with excellent winning chances.
Simple no? |
|
| Jan-24-20 | | centralfiles: After all is said about these lines i must admit in conclusion that your
10...Ne6 seems fine and probably equalizes without much of a problem while the recommended 10...Nc2+ is busted in all variations IMO as demonstrated above. |
