quiescence search vs singular extensions

[kaustubh]

Which is better to avoid horizon effect quiescence search or singular entensions.

Kaustubh,

They are really two different things. The quiescent search is a vital component of any chess program - without it a chess program will play extremely weakly. In contrast Singular Extensions is a tactical extension that only works for a few engines.
