|Feb-17-12|| ||hedgeh0g: Beautiful double rook sac and finish. I can't get enough of this opening as White.|
|Feb-18-12|| ||Shams: <hedgeh0g> On 6...a6?! nobody can get enough as White. The question is, how do you do against 6...c5 when White wins the exchange on a8? I hate that line, Black has all the fun.|
|Feb-18-12|| ||hedgeh0g: I consider 6...c5?! to be a mistake. 7.Bxe7 is the natural follow-up, upon which recapturing with the king is probably best to avoid the Nb5 business. 7...Qxe7 is also playable, but I think White gets an advantage after 8.Nb5 O-O 9.Nc7. The centre collapses, true, but I think White can get good piece play and retains attacking chances on the kingside with the advanced h-pawn.|
Could you give an example line which you find problematic as White? I'm always interested in analysing the Chatard-Alekhine.
|Feb-28-14|| ||Check It Out: What an exciting game. Interesting notes, <Shams> and <hedgeh0g>.|
|Aug-01-18|| ||birimbombum: So... what you say of 6...O-O?|
|Dec-28-19|| ||An Englishman: Good Evening: Figuring out the sacrifices required proved much easier than figuring out the order in which to play them. That took work.|
A little surprising that the gambit (in my youth called the Albin-Chatard-Alekhine Attack) has never become a main line in the French; White wins a lot of games including a lot of brilliancies. Maybe 6...h6 gives Black the best chances.
|Dec-28-19|| ||al wazir: What happens after 14...Nbd7 ? After 15. Rxh6 gxh6 16. Qxh6 Qe7, I don't see a win. If 17. b4, then 17...Qg7, and black is up an exchange.|
White can just play 15. the immediate b4, but after 15...Qxg6 16. bxc5, white has again given up an exchange for nothing much..
|Dec-28-19|| ||Jimfromprovidence: This one is tough because the after 14 Rxd5, 14...exd5 is a terrible move. |
I guess the logic behind 14 Rxd5 is to give up the rook so white can gain access to d5 to play Nxd5 seeing Nf7+ sometime after Rxh6. How white saw all of this and in the correct move order is beyond me.
Just a small note. Here is the position after 14 Rxd5 exd5 15 Rxh6.

|Dec-28-19|| ||goodevans: Well, I haven't seen it called <Rumania> for the longest time. Sometime in my youth it suddenly changed to <Romania> for reasons I've never got to grips with. I don't even remember a transition, just an instant switch.|
|Dec-28-19|| ||agb2002: Black threatens dxc4 and Qxg6.
The semi-open h-file and the bishop x-raying the black king suggest 14.Rxd5 followed by Rxh6:
A) 14... exd5 15.Rxh6
A.1) 15... gxh6 16.Qxh6
A.1.a) 16... Qe7 17.Nxd5 Qg7 18.Ne7(f6)#.
A.1.b) 16... Rf7 17.gxf7+
A.1.b.i) 17... Qxf7 18.Nxd5 Qg7 (18... Nbd7 19.Ne7#; 18... B(N)e6 19.Nf6+ Qxf6 20.exf6 Kf7 21.Qg7+ Ke8 22.Qe7#) 19.Ne7+ Kf8 20.Ng6+ Ke8 21.Qxg7 wins decisive material.
A.1.b.ii) 17... Kxf7 18.Qf6+ Kg8 19.Nxd5 B(N)xe6 20.Ne7+ Kh7 21.Bxe6 N(B)xe6 22.Qxe6 with three pawns for the exchange and attack (threatens Nf3-Ng5+).
A.2) 15... dxc4 16.Rh8+ Kxh8 17.Qh4+ Kg8 18.Qh7#.
B) 14... Nbd7 15.Rd6 Qxg6 16.Nf3 looks good for White (16... Qxg2 17.Rg1 is surely suicidal).
C) 14... Ne4 15.Rd3 Qxg6 16.Nxe4 fxe4 17.Rg3 Rxf4 18.Rxg6 Rxf2 19.Rhxh6 and White looks better.
|Dec-28-19|| ||Anjeneyar: Annotation at end says:
19.....Qd7. 20. Be6+ etc with value as +12.35.
There is a better continuation as follows:
20. f7+. Bxf7.(forced to avoid mate)
21. gxf7+.Qxf7.(forced to avoid mate)
22. Qg6+! Kh8 (forced to avert mate next move)
23. Bxf7. Nb/d3+ spite check to prolong mate
24. cxb/d3. Any move
All forced moves to try avoid immediate mate.
So the annotation should have said
If 19....Qd7. Then 20. f7+ and mate in five moves!
|Dec-28-19|| ||goodevans: <Anjeneyar> After 20.f7+ black has the option of playing 20...Qxf7, which loses horribly but avoids an immediate mate. So I'd say SF's 20.Be6+ and your 20.f7+ were roughly on a par.|

|Dec-28-19|| ||catlover: What a beautiful game, from the opening all the way to the finish.|
|Dec-28-19|| ||scormus: Instructive game, for me at least. Playing it through I thought that B's opening play was rubbish, starting with 6 ... h6. But engine analysis shows, to my surprise, that most of the next several moves were definitely playable, and as <RV> pointed out B would be OK after 11 .... cxd4.|
The sac on d5 looked winning, so it was even more surprising to me that B's position was still just about defendable (according to the engine anyway) after 14 Rxd5. As long as he played ... Ne4, but not after .... exd5??
What makes this so instructive? I suppose the realisation that the engine eval is not the only indication for the position. Here B was one step away from totally lost
|Dec-28-19|| ||dhotts: Tremendous precision was required to make the attack a success, very instructive!|
|Dec-28-19|| ||patzer2: For today's Saturday puzzle, I picked 14. Nxd5 as my solution. I thought I made a mistake when I checked Stockfish 9 at chessgames.com and saw Black as equal after 14. Nxd5 exd5 = (0.00 @ 23 ply analysis of move 14...?).|
However, <Random Visitor>'s much deeper 45 ply analysis with a stronger version of Stockfish confirms 15. Nxd5! +-
is a winning best move. I learned a few useful tactics by plugging <RV>'s deeper analysis into my Stockfish 10 and exploring the side variations.
P.S.: Looking at <Random Visitor>'s analsyis of an improvement over 11...0-0?!, castling into the attack, it appears deferring castling and developing with 11...Nc6 = gives Black equality.
However, since 9. dxc5! ± to +- improves earlier for White, Black needs to look for an earlier improvement. I'll explore and look for one later.
For now I'm enjoying the semi-final game in the NCAA FBS football playoffs between LSU and OU and getting ready for the Clemson vs Ohio State.
|Dec-29-19|| ||patzer2: Early in the opening, instead of 4...Be7, I prefer the slightly more popular move 4...dxe4 as in Black's win in E de Haan vs A Donchenko, 2019.|
If Black must play 4...Be7, then after 5. e5 Nfd7 6. h4, instead of 6...a6 7. Qg4 ⩲, I prefer 6...Bxg5 7. hxg5 Qxg5 = with dynamic equality as in the drawn correspondence game A Kazoks vs J Cote, 2001.
