January was a big month in chess, with the Tata Steel super-GM tournament and the start of Gibraltar Chess as well as various other strong events! But whether you tend to play in open tournaments, round robins or team events, there's something for every occasion in the 1.d4 d5 complex, from razor-sharp Botvinnik Variations to solid Semi-Slav systems! However, we'll see in this update that White has his weapons too, with the Chebanenko Slav in particular being challenged on various fronts! It will be a long journey through the forest of variations, but you will be a lot wiser when you reach the end.
So let's get started!. The Positional Route to an Advantage - non-Nf3 Exchange Slav with 6.a6 D10This game is specially for the chess pythons among you - who like to squeeze the opponent, kill all their counterplay and gradually tighten your grip on the Black position until it collapses.
I've previously talked up the Exchange Slav with 1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.cxd5 cxd5 5.Bf4 Nc6 6.e3, but at least we complete my coverage of this system with 6.a6 and now 7.Bd3 Bg4 8.Nge2 e6 as played in:White's plan is very straightforward - castle, get a knight to c5 preceded by Rc1 and Na4, kick their bishop with f3, and if they bring the bishop to d6 you can bring your knight to f4 to 'win' their bishop for the knight. OK, there's no need to throw Black's system completely out the window as he has a narrow path to equality.but your opponent is not likely to find or know it if he didn't read my notes! And in any case I find White's position to be a lot easier to play in these lines.Old School Lines in a Modern System - Chebanenko Slav (4.a6) D15Whenever I write one of these updates, the question that always comes to mind is - what trendy variation do I analyse and which do I shelve for 'next month' or for when more games are played? And sometimes, in flexible variations such as the Chebanenko with 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 a6, there are a lot of options which are all played a bit, but not enough to necessarily deserve an update on their own.
So I decided to overview all of the key lines from the last 8 or so months, starting with the game where White put the blot on the trendy 5.c5 Bf5 variation with 6.Qb3 Qc8 7.Nh4!:We've seen previously that Black dreams of executing the.e5 break in these structures, but now this proves very problematic and Wang Yue methodically won both our main game and a previous game from this position. The game almost represents a 'Guide' in terms of the alternatives to 5.e3 Bf5 (see next game), with lots of interesting ideas for both sides - don't miss my antidote to the 'old school' 5.e3 b5 6.b3 Bg4!Play Nh4 and White is Better - The Hybrid Chebanenko with 5.e3 Bf5 D15I'm not sure what we should name the 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 a6 5.e3 Bf5 variation which has taken GM practice by storm (and almost replaced 4.dxc4 as the main 'Classical' interpretation of the Slav). I was thinking the 'Vallejo' Chebanenko as he was the first GM to play it several times, but Morozevich was the first super-GM to try it, Timoshenko was the first GM to try it, and a certain Michael Hoffmann was the first to play it in two games. Maybe this is a puzzle for our ChessPub Forumites to solve?Anyway, however you name it, I have a different formula to suggest on this occasion - play 6.Qb3 as in and play Nh4 as soon as you can afterward!In the game White went for a different approach involving a piece sacrifice starting with 8.a4, which also sets Black a lot of practical problems as I show in the notes. But my recommendation is still to go for 7.c5 a5 8.Nh4! - and if you are feeling lazy, you can cut out a lot of theory by inserting 6.Bd2 e6 and then play 7.Qb3 followed by 8.Nh4!, still with good chances of an edge.
In short, the ball is back in Black's court!.Throwing the Gambiteer on our Turf - Vienna Variation with 5.e4 Bb4 6.Bxc4 D24If you play the Vienna with 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 dxc4, you probably find that your opponents aren't overly ready for it (as it's not as trendy as most other reasonable 4th moves), but when they are armed to the teeth with computer analysis, they come to the board and confidently bash out 5.e4 Bb4 6.Bxc4! Nxe4 7.0-0, intending to make you suffer for your material. But I'm going to give you a shortcut that will probably come as a surprise to your opponent - not Eljanov's recent 7.Nf6, but 7.Nxc3 8.bxc3 Bd6 which I think is no worse than the main move 8.Be7:The main argument against this is that White can go for the hack with Ng5 moves, but my analysis shows that if Black keeps a clear head (and remembers a few of my novelties) he is 100% fine. You can always kick the knight away with.h6 or play.Nd7-f6 to guard your h-pawn against an attack, see.

In any case, I think this line will become more popular and it scores better than 8.Be7 (where Black has been losing a lot of late), so give it a try and share your game in the Forum!.The Certified Fresh Variation - QGD with 4.Bg5 h6 5.Bxf6 Qxf6 D30The title for this game is a play on the movie reviewing website Rotten Tomatoes - here I'll be giving my latest suggestion for when we don't want a long theoretical battle and want to make our opponent 'play chess' from the early moves instead of wheeling out their prepared theory!
