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)

centralfiles: However before we close the book on ...Ne7 What about 9...b5! Bb3 cxd5 [DIAGRAM] Now white will no longer be able to play Bb5+ making the knight sac less attractive. Though Black gets shakier pawns and probably a slightly worse endgame in some lines.

  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.
Apr-20-15
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.

http://www.forum-schacharena.de/boa...

Correct?

If so: what do you want me to do?

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

  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.

  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.

  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.

Congrats on making Bookie.

  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>
Mar-24-16
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...

  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? :)
Mar-24-16
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


click for larger view

e6+!?
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?

  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. :-)
May-27-16
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?
