yesthatwasasac: Although I'm posting this 6 years after the last comment, I think it is correctly labeled as a QGD Vienna Variation, as that's what the first 4 moves are. There are a lot of transpositions possible in the Vienna, as there are in a lot of openings. So, this might go right into

  yesthatwasasac: I think this is where and how I build up this chessgames dot com forum thing. If so, I hope to compile some ideas about games I'm looking at here-- probably bad ideas, as I'm not a particularly good player and the ideas will mostly be off the top of my head with a little help from engine fumes.

If anyone is reading this, thanks for stopping by and taking time to do that. I hope at the very least you find better ideas for yourself!

  yesthatwasasac: I'm looking at this game:

A S Rasmussen vs B Jorgensen, 2017

as it follows a line in the Dangerous Weapons: The Queen's Gambit book By Palliser, Flear, and Ward.

The book presents the very early g4 as a dangerous weapon for white to try out. In this game it quickly turns into a dangerous weapon for black, and white's position falls apart painfully if not quickly.

A line I asked the engine here to look at, running on fumes, is 10. Qxd5 because I figure a liquidation attempt is better than what happens in the game. The computer might agree because it gives an eval of +0.40. Nothing to write home about, but I don't think the game ends that well for white as played.

But, the devil is in the details as they say, and saying 10. Qxd5 gets an eval of +0.40 is not enough without looking over the line. The computer's line follows what I in my meager mind would imagine to be reasonable up until move 16:

1) +0.40 (22 ply) 10...Qxd5 11.Nxd5 O-O 12.h3 Nge5 13.Nxe5 Nxe5 14.f4 Be6 15.Nc7 Bb4+ 16.Ke2 (hmmmm. is this the best place for him?) Bc4+ 17.Kf2 Rac8 18.Bxc4 Nxc4 19.Nd5 Bc5 20.Kf3 Nb6 21.Rd1 Rcd8 22.e4 Nxd5 23.Rxd5 Rxd5 24.exd5 Re8

I should apologize now because I don't know how to make a fen diagram to stick in here to show what I on about.

I realize computer lines have to be given chances to self-improve, that it will drift away from best play, or perhaps more importantly the best plan, like a ship on the ocean relying on dead reckoning. So, with that in mind, I'm thinking 16. Kf2 is the better move. Black's knight is still attacked, as is his queen's rook and his light squared bishop.

I don't know how black continues without losing a piece, but I don't know how white consolidates his position which is a mess. At the moment I think this looks like the best continuation: 16. Kf2 Rac8 17. Nxe6 Rc2+ 18. Kg3 Re8 19. fxe5 Rxe6.

Yes, black gave up a piece, I'm not sure he can avoid that in the position unless he varies his play earlier. Trading queens might not be forced. But his pawn structure is fine, his king is nicely placed, and white's king out carousing the streets at 2 am more lost and drunk than drunk with power, while his pieces are all on the back row. Black is active. I started off calling this an improvement over the engine's funes for white, but white still has a lot of work to do to make good on his extra piece I think.

Returning to the original computer line, which played 16. Ke2, the next point of interest for me is 20. ... Nb6. Black is piling on the e pawn, and that knight was a part of it before the computer moved it to what we used to call black's Queen's knight three.

When looking at the position prior to that knight bailing out on the e pawn attack, I first considered 20. ... Rfe8, because it attacks the pawn, takes a semi-open file, activates an otherwise dormant rook, and covers the e seven square, over-protecting it and freeing the bishop from having to cover it. Black can't really feel free in the game if there is a knight ready to fork his rook and king.

The attack on the e pawn could end with a simple push of it with 21. e4, where 21. ... Nd6 looks interesting in light of 22. Re1 Nf5 looking clever if not good.

I'm ready to take a step back here and, in a little while, look at: this position, the previous queen trade, and the rest of the computer's line.

The end position of the computer's line, where white has a centralized king and an isolated passed queen's pawn is an ending worth looking at in and of itself.

I'm kinda satisfied that these positions look pretty interesting. If anyone is reading this, I'd love to know what you think and especially where you see me going wrong. Thanks for reading!

  yesthatwasasac: I returned to that Rasmussen Jorgensen game, where I considered 10. Qxd5 to be an improvement. The analysis I got fell in line with what I would hope for if I were playing white, that Black would trade queens. I considered a couple of variations on the analysis, but never really questioned the initial assumption: that Black would trade queens. 10. ... Qe7 has to be considered. It protects the bishop, and keeps the focus on Black's developed pieces in comparison to white's bad development. I'm not quite convinced 10. ... Qe7 is the best move, but my next comment or post here will hopefully come to a conclusion about it, and about the position in general.

  yesthatwasasac: This is an interim note about Rasmussen Jorgensen game discussed above. Either I completely missed it at the time, or someone ran the game through an analysis. The game is now published here on ChessGames with Stockfish's annotations.

Quick highlights of that are: the computer does not like this g4 business (cue Iggy Pop's "No Fun"), black has an improvement over his early ... c5, and Stockfish's intuitive 'fumigation' (what I'll be calling running the engine on fumes, and I'm sure someone else came up with that first) agrees with a full revving of that engine to a depth of 27, that the Qxd5 liquidation is best.

I'll be looking more at this and posting diagrams and striving for not just seeing the eval but understanding them here. With that said, ChessGames is a seriously great resource. A S Rasmussen vs B Jorgensen, 2017
