Paul Keres quotes:

In complicated positions, Bobby Fischer hardly had to be afraid of anybody

Chess is a test of wills.

I was unlucky, like my country.

In the endgame, an error can be decisive, and we are rarely presented with a second chance.

A player can sometimes afford the luxury of an inaccurate move, or even a definite error, in the opening or middlegame without necessarily obtaining a lost position. In the endgame ... an error can be decisive, and we are rarely presented with a second chance.

An innovation need not be especially ingenious, but it must be well worked out.

Even the best grandmasters in the world have had to work hard to acquire the technique of rook endings.

However hopeless the situation appears to be there yet always exists the possibility of putting up a stubborn resistance.
