The move of the a-pawn has certain advantages however: the long light diagonal is not blocked so that it may be possible to fianchetto the QB with greater effect; ...c5 is sometimes desireble in these variations and to play it after ...c6 obviously involves a loss of tempo; the knight is not deprived of the square c6. Against all this it may be objected that Black does not have any control over d5 as he does after 4...c6 and also that no avenue is opened for the deployment of the queen on the Q-side (at c7 or a5).

K&B The Modern Defence CH06, 07 & 08 - The Three Pawns Attack "Three Pawns Attack = 3PA = f4, e4, d4 can only arise if Black chooses the move order 1...g6, 2...Bg7, which is designed to avoid variations where White plays an early Bg5, and to keep open the option of employing ultra-modern plans involving ....a6. Using this move order Black still runs the risk of the 3PA and of transposition into the KID, or lines of the MD where White can play 3.c4. The 3PA is distinguished from the kindred Austrian Attack by virtue of the fact that White retards the development of his QN in favor of early expansion in the center and on the king's wing."---Keene & Botterill 1.e4 g6 2.d4 Bg7CH06 Part 1 - 3.f4CH07 Part 2 - 3.c3 d6 4.f4CH08 Part 3 - 3.c3 Black avoids the 3PA [Contents]

What you will find here are the games given as examples in the book "The Modern Defence" by Keene and Botterill 1972.While studying the book I located these games in online databases so that I could play through them to better visualize and understand the variations. The book is written in descriptive notation which I find very difficult to follow. So these are a big help.While doing this I compiled a list of the URLs of these games so that I could go back and review them at some future time. With a little extra formatting these lists have been made available here for anyone who wishes to use them in a similar manner. Games which could not be found online are indicated by **.I have included only very brief comments by the authors. To do more might be an infraction of copyright. So the user will not have the benefit of knowing when a line might be good or bad for Black or for White. In general: A) represents questionable but playable variations B) better than a C) or D) etc - the best linesThe book can still be obtained at various sources online. I am not doing this to promote sales of the book but rather as a study aid for anyone interested in the Modern Defense. Following these games with the book is the best way to benefit from these lists. As of December 18, 2014 the first six chapters have been posted.Feel free to submit comments. I hope you find this beneficial.--- wormrose return to contents

We give just one rather attractive example." ---K&B Birbrager vs Suetin [Contents]

The Averbakh System "This system, named in recognition of Averbakh's victories with it in the 1958 USSR Championship and at Hastings 1959-60, is frequently favored by players of the white pieces who prefer queen's pawn openings and are quite happy to steer the game into a conventional King's Indian. Thus the great majority of games with the Averbakh System will commence with 1.d4 rather than 1.e4." ---R.D. Keene & G.S.

15 The Avante Garde "This section is wholly devoted to new and original ideas as yet in the embrionic stage which can hardly be treated with any pretence to exhaustive accuracy. In what follows, therefore, we shall content ourselves with a general exposition of the positional ideas underlying these novel schemes combined with illustrative examples from the play of those pioneers who are helping to add a further dimension to chess theory." ---Keene and Botterill (written in 1972) 1. The Double Fianchetto Defense Ardiansyah vs Larsen 1970 Garcia Larsen 1970 Darga vs Keene 1971 2. The Hippopotamus The Hippopotamus is in a way related to the Double Fianchetto, in so far as here too Black deploys his bishops at QN2 (g7) and KN2 (b7). However whereas the Double Fianchetto is an answer, based in a single positional theme (control over the light squares, especially e4), to a specific move-order by White, the Hippopotamus is rather the deferment of any answer, Black develops within his own three ranks of the board, entering into no territorial struggles, according to a fixed plan of development --- --- and various permutations thereof as well as the eccentric J.C. Thompson's book ---that is virtually independent of what White is doing in the meantime. One might characterize Black's play by saying that he proceeds like a man who has never learnt the rule that a pawn may take two steps at his first turn, and indeed the Hippopotamus is reminiscent of some of the old Arabic openings that could be played regardless of the formation the opponent was adopting. Such strength as the Hippopotamus has derives from the resilience of a cramped but not compromised position, and the dangers White will run of 'trying too hard' and being tempted into a rash advance.
