1. e4 e6 2. d4 d5 3. Nd2 Nf6 4. e5 Nfd7 5. c3 c5 6. Bd3 Nc6 7. Ne2 cxd4 8. cxd4 f6 9. exf6 Nxf6 10. Nf3 Bd6 11. O-O Qc7 <12. h3> O-O 13. Be3 Bd7 14. Rc1 Be8 15. Ng5
This is the key position in this line. After 15...Qe7 (15...Qd7 or 15...Bf7) White continues with 16.f4. >
Boy, 14. ..Be8 sure is ugly! It just invites Ng5. I'd prefer 14. ..Rae8. The defect in blacks position is the backward E pawn which f4 is intended to exploit. After Rae8 black can answer Ng5 (and probably Bg5) with h6 kicking the knight so white can't get in f4. I'm no expert in this system, but Rae8 seems to be in line with blacks long term purposes, and an eventual e6-e5 break, possibly even at the expense of the D pawn in order to launch a kingside initiative. It also lets black hold the dark diagonal and he can now retreat the Q to b8 to unpin the knight. Maybe if someone has the time they can plug this position into Rybka and Houdini.

14...Rae8 is the most popular move (I would also prefer it as Black), but 14...Be8 is a playable alternative. Recently, SIM Paul Tufler opted for 14...Be8 at the 35th World CC Championship Semifinals
It is important to note that my cooperation with <kb2ct> was a part of our preparation (as White) against GM Akobian's French Defense. Against GM Adams we will play with the black pieces. That is quite different perspective.
|Apr-27-13|| ||DcGentle: <kb2ct>: As far as I know, you love endgames. Currently <truefriends> is playing the endgame of his life, it's a momster endgame with 4 bishops and 9 pawns.|
This is the game leading to the endgame:

White already wasted some moves, but I needed quite some time to learn what was going on here. My first tries were not good, and this is an understatement.
But now I have the solution and checkmate is around move 100.

4 bishop endings are rare.
There are no majorities and a draw is likely
|Oct-18-13|| ||Abdel Irada: Still rarer are 21-bishop endings. ;-)

Well, White has a surplus pawn in this ending.
See here for more:
This ending helps me a lot with my new paradigm engine.
All the best,
|Feb-18-14|| ||perfidious: With equal material and no majorities, I found a way to lose the four-bishop ending to a future grandmaster in A Shaw vs E Perelshteyn, 1996.|
|Feb-18-14|| ||DcGentle: <perfidious>: Very nice endgame, and I know that these 4 bishop endgames are among the hardest.|
It's not easy to see by any means, that <47. Bd2> could have hold the draw, apparently.
Thanks for the link, quite useful.

cro777: <iatelier> At the Lomonosov, the 7-piece tablebases have been developed. Currently, ICCF has free access to 6-piece positions. Access to 7-piece tablebases at the moment is not free.

Premium Chessgames Member AylerKupp: <<cphoenix> Do the downloaded tablebases need to be placed in a special location?>
No. I have a folder called, naturally, Tablebases, with subfolders called Tablebases\Nalimov, Tablebases\Gaviota, and Tablebases\Syzygy, but that is arbitrary. It's better to keep the tablebases separate from the engine because multiple engines use the same tablebases so it's easier to reference them if they are in their own folders. For example, Critter, Houdini, and Minko use Gaviota tablebases; Hiarcs, Protector, Rybka, and Spike use Nalimov tablebases; and Houdini, Komodo, and enhanced versions of Stockfish use Syzygy. Yes, Houdini can use all 3, but only one at a time.
Depending on your GUI (I use Arena but others are similar), you can specify the tablebases folder either in the GUI (for historical reasons) or in the specific engine UCI parameters section. Because the Nalimov tablebases were the first widely available tablebases, the folder for these are typically specified in the GUI. But you then specify other tablebase folders in the UCI parameters for each engine. For instance, Houdini can use all 3 tablebases so its UCI parameter section gives you the option to specify the folders for each of the 3 tablebases.
