    Playing against IQPs

    Quite a lot written about IQPs is misleading, but looking at actual games should provide better guidance. If you want a whole book about this structure, see Baburin's Winning Pawn Structures.

    • The commonest advice is blockade a Pd4 with a Nd5 (here I am assuming that it's White with the IQP). But Black loses a lot this way, since this N is in his own half of the board, and White can easily work around it; it even shields the pawn from frontal attack. Sometimes White wins on by K-side attack, e.g. Gulko – Kaidanov, USA ch 1994, and others by sustained positional pressure, e.g. Karpov – Hansen, Wijk aan Zee 1988.
    • Certainly, Black must watch out for a deadly d5 by White, e.g. Kamsky – Short (cand.) (1/2) (PCA) 1994, which is why Black likes to blockade it. Indeed, even Karpov has fallen for d5 a few times, e.g. against Kamsky in their FIDE world championship match, 1994.
    • But in another game in the match, Karpov improved, not by blockading with the N, but rerouting it to f5 to attack the IQP, then using the B to blockade.
    • Even the common advice to swap down into an endgame isn't necessarily great, because Black can even hold the dismal bad B v N endgame, if he's careful as Capablanca was against Flohr.
    • No, an enemy IQP seems to be best exploited in a heavy pieces middlegame or endgame. Here, the rook can function as [/I]both blockader and attacker. Also, the defending heavy pieces often must be behind the P, so it becomes pinned and thus vulnerable to a pawn attack, e.g. in an ancient game of mine where 34. c4 attacked not one but two pinned IQPs. A classic game illustrating the drawbacks of the IQP with heavy pieces, including the pins, is Korchnoi – Karpov, World Championship Meran 1981.
    • The strength of a R as blockader, and the disadvantage of a heavy pieces for the IQP side, is also shown strongly when a B of the same colour as the IQP is added to both sides. This can't dislodge the R from its blockade, and Korchnoi couldn't defend this sort of position any better in a later game with Karpov (1988).
    • Even if the IQP can't be won, its defending heavy pieces are often too passive to cope with action elsewhere, e.g. Botvinnik – Zagoryansky, Sverdlovsk 1943 where the side playing against the IQP switched to a K-side attack.
    • Karpov showed the strength of heavy pieces against the IQP against Spassky (Montreal 1979), even with a pair of Bs each as well. Here, like the Botvinnik game, Karpov tied down Spassky's majors then went for a K-side pawn storm. But when Spassky went pseudo-active with 33... g5, Karpov went pack to the IQP and expoited the usual pin with 36. e4.

    “There’s no point blaming the tragedies of socialism on the flaws or corruption of particular leaders. Any system which allows some people to exercise unbridled power over others is an open invitation to abuse, whether that system is called slavery or socialism or something else.”—Thomas Sowell
