Space and potential (mud, mud, glorious mud)

How do you play against the Hippo? It's all about Space and Potential. At risk of sounding like an estate agent, I propose to describe my limited understanding of these issues...

Space

All else being equal, it's an advantage to have more space. More space means you can get about the board more easily, organise an attack more easily, and sometimes all your opponent can do is sit tight while you work out how to win:

this game, but not because of this move! Black was able to handle any pressure, probe for
weaknesses, and eventually hit back with a bid to establish their own stake in the centre.}

What's going on here?

We have two very different cases: more space with a fixed pawn centre, and more space with a fluid centre. When things are not fixed, the side with more space may have to watch out for counterplay right across the board. There are half-open files, sort-of outposts, and the possibility of a break on the side you take your eye off! These days, the half-open centre is often contested in the Scotch, Caro-Kann and sometimes the French Defences.

Half-open centres

  • ...e5xd4, Nxd4 in the Scotch Game
  • ...d5xe4, Nxe4 in the French and Caro-Kann
  • ...c5xd4, Nxd4 in the Sicilian

White has more space, and, while Black has counterplay, sometimes that's what decides the game. White can organise an attack, and if things break open, can occupy key squares and lines more easily. White can add importantly to the space advantage with f2-f4 or c2-c4.

On the other hand, as Tarrasch said, "Chess is a terrible game. If you have no center, your opponent has a freer position. If you do have a center, then you really have something to worry about!"

We'll have one more advertisement for the centre before considering its burdens.

The Maroczy Bind: c4 and ...c5xd4

Black's counterplay in the Sicilian often comes from a Queen's-side push with ...b5 (minority attack) or a well-timed counterblow in the centre with ...d5. Why doesn't White stop both of these ideas with c2-c4? (The Maroczy Bind). It can be crushing...

Ah, if only life was always so simple. In most lines of the Sicilian, White is not allowed time to get in this c2-c4 move at all. In others, White has time for c2-c4, but Black has time for development and counterplay. In only one or two lines of the Sicilian has the Maroczy proved to be a lasting test of Black's resources, and even there Black can play with hopes of equality or even turning around the game.

The Accelerated Dragon is the most common place where we see Binds, and Black can hope to restrain the White structure, swap off all White's best pieces, and go for a QN vs QB endgame. That happens perhaps more often in Black's head than on the board, but this might do as an exanmple:

I've often had Black knights crawling all over the dark squares on the Queen's-side, but still won the game, because Black lacked the capacity to follow through with anything meaningful.

Hedgehog with Bb7 and Nbd7

Mihai Suba wrote an amusing book about the Hedgehog, Dynamic Chess Strategy. He suggests that White can easily and quickly adopt 'perfect' but unimprovable position, and, while Black may be cramped, can always find ways to improve things. It's a psychological problem as much as a chess one, but it is a problem, and no more clearly seen than in this game from Chess for Tigers:

Double fianchetto hedgehog

It exists, but you don't meet it very often, as it's something of an extravagance. d5 is very inviting for a Knight, and if chased off with ...e6, the Black dark-squared Bishop cannot cover d6, f6 and h6 all at once.

I had some ideas of probing the dark squares with Ng4 which may have made my illustrious opponent nervous, but Stockfish is unimpressed.

The Hippopotamus: double fianchetto with a full board

The Hippopotamus is often used in this formation:
r--qk--r
-bpnnpb-
pp-pp-pp
--------
Black has the entire second rank covered, has no obvious weaknesses and can probe with any pawn at any point.

Double fianchetto systems are as old as chess, but the Hippo looks and feels a bit fishy to many when adopted by Black and with the half-smothered Knights.

Yet, there are many great players who have tried it as Black and even more great players who have made no progress against it as White. Keene and Botterill give as evidence a game of Keres who drew against Navarovsky's Hippo (1/2-1/2, 27 moves) and Petrosian's two draws against Spassky's beasts.

Potential

"Never mud-wrestle with a pig. You both get filthy and the pig enjoys it!

The Hippopotamus is one of chess's dirty little secrets. In a repertoire book by White, you will rarely (never?) see a recommendation of how to play against the Hippo -- for example, it failed to make even the chapter titled 'Garbage' in Sam Collins' 2004 book -- but players at all levels wheel it out and survive and even thrive with it. Black's position is 'cramped but not compromised', in the words of Keene and Botterill, and White can easily over-stretch, just as against the the Hedgehog. Every advance by White loosens the position, and Black may be well-placed to take advantage of new opportunities.

Jonathan Rowson wondered aloud if the Hippo has now just about made it onto the 'respectable' list, where Black's potential is compensation for White's space or initiative (Chess for Zebras, page 237) -- the argument here is similar to Suba's point about the Hedgehog. As Tartakower once remarked, White has their initiative to defend!

So far, so general. It's probably better to look at some specific formations.

With Black having full pawn control of the fourth rank, it's almost certain that White will have to break through with a pawn move. However, e4-e5 can be readily met by ...d6-d5, getting into a sort of French Defence centre with White's pieces in front of the c- and f-pawns, which they might want to move. Black can quickly follow up with ....c7-c5 and perhaps ...f7-f6, and White may regret pushing the e-pawn!

Similarly, after d4-d5, Black can reply ...e6-e5, getting a King's Indian sort of centre where ...f5 is easy for Black to achieve, while c2-c4-c5 may be a long way off for White.

White can hope that Black's weaknesses on the wing where White gets more space (King's-side in the French, Queen's-side in the King's Indian) are enough to override any inconvenience from advancing a pawn. Whizzing through a number of 2500-level White wins in the Hippo, this seems the most common way of winning.

White gets in with a break

White can try and arrange some other sort of breakthrough, perhaps using some other pawn. Sometimes the breaks work, sometimes they don't; sometimes one or other side gets in on the wing, even while the central situation is unresolved:

The three-pawn centres against the Hippo

With the adjustment of a Knight and the advance of the c- or f-pawn, we have a three-pawn centre hippopotamus, and now Black needs to take notice, as the White centre is much more solid. Black can hope that while White is arranging all this, Black can sort out some way of meeting it, or provokes White into advancing before they are quite ready by some wing advance of their own.

Some of the most critical lines against Hippo structures start by White aiming at a three-pawn centre from the very start.

def centre against the Hippo

I would have guessed this was risky for Black. Nigel Davies has made a good case for it but Tiger Hillarp Persson doesn't recommend it in his book on the Modern, preferring to expand while possible with ...b5, and only permitting the luxury of the Hippo once White has committed to blocking both Bishop's pawns.

cde centre against the Hippo

This can arise from the English Defence

Miles and Short have both dabbled in it, pointing at White's slow 3.a3 as justification.

In Danny King's book on the English Defence, he suggests an early h2-h4 can critically restrict Black's chances to expand, as shown in a couple of Milov-Miles games.

Nakamura rather provocatively tried it against Kramnik when White had wasted no time at all... In a King's Indian formation, the typical advance c4-c5 arrived with lightning speed.

Move orders

People that know me won't be surprised that I wonder if the Hippo can be move-ordered. I haven't hit on anything yet, but there are some specific move orders that Black is well-advised to avoid:
