Here is a few I can think of End games that are drawn.

1. Bishop+King -- King
2- Knight+King -- King
3.( 2 ) Knight + King -- King
4.( 2 ) Bishop + King -- King
5. Knight + Bishop + King -- King

Play Chess at:http://www.GetClub.com/Chess.html

What about below combinations are they draw?

Rook+king -- Queen + King?
Rook+King -- Knight + King?
Rook + King -- Bishop +King?

Queen +King -- Knight + King?
Queen +King -- Bishop +King?

Are there any other combination where the Game is drawn? As I will use
it for automatic Draw at GetClub Chess.


Since your program cannot be expected to detect
all conceivable drawn positions, it is wise to focus
on the simplest ones first:

K vs. K = insufficient [i.e. nonexistent] mating material

K&N vs. K = insufficient mating material

K&B vs. K = insufficient mating material

K&B vs. K&(B of the same color) = ditto

--------------

Look at the following position:

White: Kd1, pawns on a4, d4, g4

Black: Kd8, pawns on a5, d5, g5


It is impossible for either side to make any
headway because the pawns are fixed and
there exist no legal entry squares for the
Kings, so this too is drawn. However, for
the GetClub program to detect this kind of
draw, it would require connection to an
/artificial intelligence/ (like IM Innes' brain, for
instance).

The other examples at the top of this post
were not draws in this respect; some are
draws with best play and some are wins with
best play, but either way their cases are
handled by the threefold-repetition rule or by
the fifty-moves draw rule.
