After 1.d4 Nf6 2.Bg5 Ne4 3.h4 c5 my preference is for 4.dxc5 Qa5+ 5.Nd2 Nxg5 6.hxg5 g6 7.c3 Qxc5 8.Ne4 following a nice game of Richard Rapport quoted in CP August 2014 (game 1). Against 4...Na6 the best line for white seems to be 5.Nd2 Naxc5 6.Nxe4 Nxe4 7.Qd5. The CP reference here is November 2018, game 1. My main reason is that I don't like 4.d5 Qb6, because this is (presumably) what the black player wants to see. Obviously 4.d5 is very playable, however, especially if you are Leela. See CP December 2019, game 2.


Definitely take another look at the 4.d5 Qb6 lines! I don't think Black should be happy to see it at all. You've got games as old as Hodgson - Sareen 1993 and as new as Sedlak - Yang, Djenovici 2018 which show what White is aiming for. The pawn on b2 does not matter if White gets active counterplay!

Hi all,

Well there's been some stuff out on the Raptor recently (chessable and ichess, and they both seem decent and give different ways to play it). I was wondering, is there a well know response for black? What is the reconmended way to olay against it? I just want to see what the critical line is and see what the author's  give vs it. Also, this is for thise who play it, after d4 nf6, bg5 ne4, h4 c5, is it better to push or play dxc5? Chessable give push, ichess gives take, both authors make nice cases for both but i wanted some other opinions. Thanks.


As of October 2019 Chess Publishing had 36 annotated games in the position after 1.d4 Nf6 2.Bg5 Ne4 3.h4. I'd look at this for critical lines.

Based on what I've read you've got two third move choice as Black. 3...c5 with the better score in the database, requiring more preparation, and very sharp. Or you have 3...d5 with less preparation, much calmer, and a worse score in the database.

For what it's worth I think Trompowsky players really enjoy the 3...c5 lines so 3...d5 is the practical choice. It also happens to be the recommendation of GM Avrukh in "Beating 1.d4 Sidelines".

Avrukh's mainline follows Vaishali - Rosen from the 2017 Lidums Australian Young Masters IM Norm Event up until move 12. Avrukh does not consider another 12th move from White aside from 12.c3 and it appears that improvements in this line are related to queen moves by White on move 12.
