Don't Count
(much)
claiming Black can't win. Pat: He can?
Noah: He can ifhe can get two of his is to dark squares.
Black can break the dark square blockade by triangu lating and then sacrificing the d-1 . His W then reaches d3 and the rest is more or less easy.
Pat: Are you saying extra is don't usually mean anything? Noah: No, they do. But you could state this rule about Hs of Opps with confidence:
Material Advantages Don't Count
(much)
A case in point is Diagram 223. White loses after he es tablishes material equality.

And White forfeited in this hopeless position.
Pat: Because he doesn't use his W to protect a vulnerable * side.
Noah: Right. He goes after the Black h-i -but that's little
help because he's miles from creating a passed <ai-side i .
Pat: I don't get it. Black goes after the b2-i even though
that doesn't create a passer for him.
Noah: No, not immediately. White lost because he al lowed Black to create two connected passers. He missed a fundamental B-of-Opp tech nique.
White failed to force the enemy fts onto the color of the enemy jt so they
could be blockaded. Pat: Like with .(tfS-e 7-d8! Noah: Correct. That would
have drawn in Diagram 224. By the way Boris Spassky, who played White here, once explained why his first two marriages failed.
The reason, he said, is he and his wives were "Bishops
of opposite color.»
Pat: Very funny. So if material doesn't matter ...
Noah: Doesn't matter much. Pat: Have it your way: "doesn't
matter much.»
But if it doesn't, what does? Noah: Proper piece place
ment -trying saying that three times fast.
Pat: Uhh, I'd rather not. Noah: All it means is getting
the .(t and W to the right squares.
For instance, in Diagram 225 Black takes his time in bringing his <aI forward be cause he knows there is some thing much more important to do in the diagram.
Pat: That's to stop the White .(t from reaching g4, right?
"Bishops of opposite color are not much good
at supporting the advance of their own pawns • • • For this reason,
the Bishop usually holds up enemy pawns, leaving
to the King the task of supporting the advance
of his own pawns. "
-Paul Keres
Noah.: Correct. When your opponent has two passed is you try to find the diagonal that covers squares in front of both is.
In this case, it means dl-h5. Pat: Can't White draw by set
ting up some sort of blockade on the light squares?
Noah.: You means with a A on h3 and � on f3? It doesn't work because the Black is are so far apart.
That's another unique as pect of "Bs of Opps" -the power of widely separated
is.
In some other positions, such as with �s, it's only a draw if the only is left on the board are your a- i and h- i . Pat: But not with As.

Noah: No, the farther apart the better.
See for yourself in Diagram 227. At first glance it looks easy because White is three
is ahead.
On second glance it looks hard because White has no passers.
Pat: I have a feeling there's gonna be a third glance. Noah: On third glance White
wins even after he creates material equality-and gives Black three passers of his own. But Black's passers are stopped-thanks to 4 . .£te5-
and Black's W and .£t help lessly try to stop promotions at a8, c8 and h8.
Pat: So unlike a middlegame, isolated is are good in these endings?
Noah: They're usually better than connected is. And the more isolated the better. Pat: Is there a rule here? Noah: Not hard and fast. But
you can say that if only two is are left and they are sepa rated by one file, it's usually a draw-because the defender's <it> can easily shift from block ading one to blockading the other.
Pat: But with two or more files in between ...
