Those who don't know better think that opening knowledge is all memorization. This is just plain not true, most successful opening play comes from understanding the positions. A good opening player will be able to figure out why certain moves are wrong despite not having seen the move before. Rote memorization rarely gets results with the lucky exception of an opponent playing perfectly into some prepared trap.

The player strong in the openings will usually try to use his knowledge to get a position where he's more familiar with the tactics and has a better idea of what the plans are and how to proceed with them than his opponent or to get a position where it's easier to play for his side. Having a theoretical "advantage" in a position you don't understand any better than your opponent is usually next to worthless.

"Just tell me what to do" That's impossible you will never gain an understanding of the positions without working on them yourself (Like most other things in life).

If anyone wishes to post analysis here on positions they are familiar with, your more than welcome.(Preferably not general comments for the uninitiated but real analysis).

Here are links to ideas already in the forum (admittedly not much at this point)

Leaving everything en prise.
on 10.Be3 Bxd4 and white barely has enough compensation.


click for larger view

Now white has a choice

C3a 11.Kh1 where the King is less exposed but Nf2+ is a possibility in some variations.

C3b 11.Kf1 a little exposed but ready to take the bishop if the opportunity arises.

on either move black will have to choose between ...Qd7 and ...Qd6, but only one works in each position!

C3a 11.Kh1 Qd6!
11...Qd7?! As the white king is not exposed White can decoy the Queen and bare the black king 12.Rxe4! dxe4 13.Ne5! Qxa4 14.Qh5+ g6 15.Nxg6 With The white king on f1 Black would have ...Qc4+ ...Qf7 holding.

after 11...Qd6 I can't find better than
12.Nc3 <12.Qh5+ g6 13. Ne5+ b5 14. Nxg6 Bg4 favors black> 12...Bxe1
13.Qxe1! <13.Nxe4 dxe4 14.Qxe1 allows 14...b5 which is comfortable for black> 13...bxc6
14.Nxe4 dxe4
15.Rd1 <Qxe4+ Kf8 Re1 Bd7 Bf4 Qc5 Be3 Qd6 Bf4 draw> Qe5! <...Qe6 Rd4!> 16.Bxc6+ Kf7
17.Bxa8 fxg5
18.Qxe4 Qxe4
19.Bxe4 =

C3b 11.Kf1 Qd7!
After 11...Qd6?! both 12.Nb4+ Kf8 13.Rxe4 dxe4 Qxd6 and 12.Qh5+ leave white better as his king picks up the black bishop at the end of the complications.

12.Nc3 bxc6 Bracing for the onslaught.
13.Nxe4 Bxe1
14.Nxf6+ gxf6
15.Qh5+ Kf8
16.Bh6+ Ke7
17.Re1+ Kd8

Amazingly Black holds as neither 18.Bg7 18.Qf3 nor 18.Bxc6 amount to much for white.

Premium Chessgames Member
  centralfiles: In conclusion
8.Bg5 f6
9.Nxd4 Bc5
10.Nxc6 Bxf2+
Leads to crazy unclear complications where It's hard to know what's going on over the board and a single misstep for either side is deadly. If you plan on using Bg5 as white you must be very well prepared and then some to stay in the driver's seat.
Premium Chessgames Member
  centralfiles: The award for the worst mistake in the 8.Bg5 line goes to MCO-15 where it is covered in a footnote to 8.Nxd4 I quote <"White may prefer the simpler line 8.Bg5 Be7
9.Bxe7 Qxe7
10.Nxd4 O-O
11.Bxc6 bxc6
12.f3 c5
13.Nc6 Qd6
14.Qxd5! Nf6
15.Qxd6 with a good endgame, Karastoichev-Paskalev, Silven 1961">

As pointed out above this line is replete with consequential errors What makes this much worse though is the contention that 8.Bg5 is "the simpler line" when in fact 8.Bg5 f6 is probably the wildest line in the Riga, with many options for both sides along the way. Contrast that with the main line
8.Nxd4 Bd6
9.Nxc6 Bxh2+
10.Kh1 Qh4
11.Rxe4 dxe4
12.Qd1+ Qxd1
13.Nxd1+ Kxd1
14.Kxh7 with an endgame.
In spite of how complicated this might look to an onlooker it's extremely simple. Black has not one alternative anywhere along the line so all white must know is the text and he has his endgame.

Premium Chessgames Member
  centralfiles: In fairness to MCO which is generally high quality, the intention of "simpler line" might not have been that 8.Bg5 leads to a simpler game but was just a way of saying white has an alternative.
Premium Chessgames Member
  centralfiles: <centralfiles><9.c4 might again be a good alternative as ...dxc3 ep 10.Nxc3 Bb4 transposes to C Doran vs P Talsma, 2009 2009 mentioned above in the 8.c4 line while avoiding 9...Be6 (see the relevant post above)>

My bad here, White CANNOT transpose to C Doran vs P Talsma, 2009 as 11.Nxe4 Bxe1 12.Qxe1 can be met simply with ...O-O as white has two pieces hanging. Instead
11.Ne5 O-O
12.Nxc6 with an equalish game (This position can also be reached with 8.c4 dxc3 9.Nxc3 Bb4 10.Bg5 f6 11.Ne5).

  lost in space: Hi <centralfiles>, thanks for you message in my forum. I think you are talking about this line/variant? So an alternative to the berlin wall or the „silent" 4. d3 lines in the Berlin for White.


If so: what do you want me to do?

Premium Chessgames Member
  centralfiles: <lost in space>
Thanks for stopping by.
Since ...a6 is a black move this shouldn't really be considered an alternative for white but rather for black.(I think Black does not do well in the berlin wall against stronger players i.e. the better endgame player takes home the point there) I was just hoping to hear from you if you Knew anything about these lines. Thanks
Premium Chessgames Member
  lost in space: Hello centalfiles,

no, I have no clue about this lines. I am a 1. e4 c5 player, at the moment hoping to understand either 1. e4 e6 or 1. e4 e5 and here I like the berlin wall as Black.

In opposite to most others I think this is a way to play for a win in the endgame with black.

Premium Chessgames Member
  centralfiles: <lost in space> Good luck then, But be warned the stronger player will win the berlin wall so you must be careful when facing stronger opponents.
Premium Chessgames Member
  lost in space: Thanks, yes, you are right. Against strong players I try to set the board on fire. Berlin is wrong here.

  jepflast: <centralfiles> I just now saw your post in my forum, sorry for the delay. Thanks for the invite, but I'm afraid I will not be of much help when it comes to this opening (or most openings, for that matter). Good luck on your quest, though.

  Penguincw: Congrats <centralfiles> for winning the Spring Leg. I thought <Chnebelgrind> was running away with the leg, but you caught up to him. You may have been denied first place during <Switch>'s first trial, but not this time. ;)
Premium Chessgames Member
  centralfiles: Thanks Penguin
Congrats on making Bookie.
Premium Chessgames Member
  eternaloptimist: <centralfiles> Hey how's it going? I just want to wish u good luck in the championship leg of bookie! I c u r in 2nd place now. I was in the top 30 of this leg for a while but I've dropped down considerably in the last week tho. It looks like <TIMER> & u hv the best chance to win but u def can't count out <SwitchingQ>
Premium Chessgames Member
  centralfiles: Thanks I'll need the luck.
I was actually hovering about the 10-15k mark for most of the leg but hit a good lucky streak in the last few days. Still another month to the leg though a lot will probably yet be happening. Good luck unto you...
Premium Chessgames Member
  Annie K.: <centralfiles> Hi! I'm dropping by to ask if maybe you'd like to be the Bookie for one of the legs in the 2016 cycle? :)
Premium Chessgames Member
  centralfiles: While I'm honored by the offer I'm afraid I'll have to decline I'm simply not online consistently enough to be able to be bookie.
Premium Chessgames Member
  Annie K.: Ok, no problem. :)
Premium Chessgames Member
  eternaloptimist: U r welcome & thx for the well wishes! Sometimes u need to be lucky in Bookie but it requires some knowledge as well. That would be cool if u would grant <Annie's> request & be the Bookie but if u aren't online enough then I guess that would make it difficult to be the Bookie.

  centralfiles: I have been experimenting very successfully for a year or two now in online blitz with the crazy e4 c5 c3 Nf6 e5 Nd5 d4 cxd4 Nc6 Bc4 Nb6 Bxf7+!? Kxf7

The deeper I'm looking in to it the more I'm beginning to think it might be strong enough for a surprise try(in blitz) even at the highest level. How would you try to answer it?

Premium Chessgames Member
  FSR: Note that Giri avoided the bishop sac with ...dxe5 rather than ...Nb6 in R Mamedov vs A Giri, 2016. No doubt he was quaking in his boots. :-)
Premium Chessgames Member
  centralfiles: you should've seen the disappointment on Mamedovs face when he saw that move... ;)

I tried to check databases though I don't have chessbase, on chesstempo there were quite a few games but white did quite well if you (discount the 9.Ng5 and 10.Ng5 games) take rating into account.

This position has netted me many free blitz points. 15...Qf8 <16.a4 is coming so black must save the knight as exchanging in center is ggod for white at every point. 15..Qd8 16.O-O followed by an evntual f4 will only make whites job easier> 16.a4 Qf5

And now I must turn to you FSR
Does white have a win here?
Perhaps just winning chances?
Or will a GM draw easily with the black pieces?
