16. Lajos Portisch vs. Johannessen,
Havana, 1966
During the first half of this game, a
Queen's Gambit Slav, the great
Hungarian grandmaster Lajos
Portisch locks up the center with a
d4-e5 structure by move 14. This
gives him a "beachhead" on e5 and
makes it hard for Black to counter-
attack in the center, which is the
standard antidote for an attack on
the wing. The next stage starts with
16. h4. Portisch announces his
intention to attack on the kingside.
He refrains from castling his own
king into safety because he knows
it’s safe enough in the center, at
least for the time it will take him to
break through with his attack.
When Black tries to trade off pieces
with 17. … Bxf3, Portisch sacrifices
a knight for an unstoppable attack
with 18. Bxh6 and then calmly
moves his king to the second rank
to bring his other rook into the
game. His Rxh4 was another bril-
liant sacrifice that crushes any hope
of defense. In the final position,
Black resigns because White will
simply play 26. Rxh6+, winning the
Black queen. If 26. … Qxh6, then
White plays 27. Qxh6+ and will
mate on h7.

Setting Up Special Positions
This is another terrific feature that
allows you to solve problems you
see in magazines or newspapers,
or that you make up yourself. It
also allows you to enter game
positions you want to play, or that
you want Touch Chess to look at,
perhaps using the Infinite Search
level.
Normally, it is easier to start from
an empty board to set up such
