Instead of 16...,Be6, which seems passive as it invites 17Nc5 with exchanges, I was wondering about 16...,Nf4 - obviously threatening the fork on e2 - with 17...,Bf5/a6 to follow, or 16...,Bf5 (17Bxd5, cd just opens up the c-file with the rooks coming to c8 and b8) followed by 17...,Nf4 and 18...,Ra/f-d8. This seems to, at least, make things a bit more interesting rather than exchanging into a so-so ending. Another option, though less appealing, is 16...,e5 with either 17...,Be6/f5 or 17...,Nf4 or 17...,Rd8 (or 17...,Rad8, if the bishop's moved). Not sure how appealing/useful these would be - no silicon pet on this laptop. Kindest regards, James 16...Nf4?? is dropping a rook on d8 16...Bf5! would be my choice for not that hard equality as GM Jones shows 16...e5?! don't like in such positions 16...Be6!? GM Jones in his book analyse it in details

I forgot one thing so I am quating myself This part of my post is not only true to Dragon. As a matter of fact this is my conslusion when studing openings in generall, the sharper variation the more moves are forced and more forced draws. I for example changed some of my original intended lines in Nmzo Indian when I discovered this thing.

	Bc4 yugoslav leeds to sharper play than 9 0-0-0, and it also increases blacks counterplay but also increases whites atacking chanses. The sharper a position are, the more moves are forced for both sides. The sharper a poisiton are and mores are forced the number of forced draws increases.

	i did a comparison of 9. Bc4 and 9. O-O-O and the only difference i found is that 9. Bc4 is more drawish and 9. O-O-O with castling on opposite sides leads to more decisive games. the analysis is available online and i would be grateful for your comments. my paper may be found by googling "pairwise comparison of chess opening variations"

	I think white has the slightly better chanses but nothing special.

The line 12...Bxd4 13.Qxd4 Qb6 14.Na4 Qc7 15.Bc4 Rd8 16.Bb3 Be6 17.Nc5 Nf4 18.Nxe6 Nxe6 19.Qe3 Nf4

leads to this ending. Isn't this slightly favourable for white?
Exchange rooks and queen, then you have bishop vs knight and solid pawns vs not so solid pawns

This very position has arisen at least twice.
In one game, Heine Nielsen drew as black against Adams and in another game Heine Nielsens girlfriend Cmilyte drew as black as well. So perhaps it's not so easy after all?
(I'm posting these two games in the next post...)

	Its been a while since last post at this forum. Today I crushed a FM who plays i swedish elite in a strange variation of 12 .. Nxc3. White played 13 Qxc3 Bh6+ 14 Be3 Bxe3 15 Qxe3 Qb6 and instead of accepting the pawn opponnet played 16 Qa3 immidiatly and after Be6 it became a standard position of 12 .. Nxc3 with the difference that material was equal and I got very good play and won by a combination after a blunder by opponent. The funny thing is that several moves later in the game my opponnet captured that e7 pawn wth the queen. However both of us had been drinking a lot before when we was at party after a mutal chess playing friends daughters baptism.

	Greetings, JamesH wrote on 06/05/11 at 20:02:27: Spree K wrote on 06/05/11 at 19:07:09: The 12...Bxd4 line has been causing White some issues, e.g., 13. Qxd4 Qb6 14. Na4 Qc7! as played by Carlsen. The current verdict seems to be that White cannot get an advantage. although these Bxd4 lines do seem to equalise, they generally seem to go into a fairly level ending, maybe a minute advantage for black in some lines. The problem personally is that when playing such a variation as the dragon, i'd like somesort of complex middle game as oppose to a rook endgame :/. Note to GMTonyKosten/Mods: Perhaps, it might be an idea to start a Endgame section where such endings could be analysed/assessed to help players - like JamesH and me! - to decide whether to try and stay in a middle-game by taking (unnecessary?) risks or bite the bullet and go for a "equal" ending. If nothing else, it may reveal that - being better prepared for such endings - there are better chances for Black to win!? Kindest regards, James

	This game was annotated at subscription section. However I think white can simply transpose to mainline instead of grabbing the pawn. Download game in pgn format

	The older, the better - over 2200 and still rising.

	Quote: finally im sure the whole "mainline" after 12...e5 cant be refuted? I imagine somone has done some more recent analysis on this line: 12...e5 13.Bc5 Be6 14.Ne4 Rb8!? my fairly dated database gives several moves for white here such as 15. Bc4 15.h4 15.g4 and 15.c4. Ill avoid posting reams of analysis here, but this position seems just consistently better for white, and black doesnt seem to get sufficient play, I hope i am wrong anyone got any analysis on this line? thanks For me the only problem with 14...Rb8 line is 15.Bc4 Re8 16.h4 f5 17.Ng5 e4 18.Bb3! Qf6 19.Bd4! and white is better. Any improvements here?
