Go up one level in this thread

Thanks Jim, I went through the ones Amy didn't solve and picked out a couple to
use (I guess I'm a bit fussy).  Quite a few of the positions are very artificial
looking, and you are right about the odd duplicate solution.

Here are the ones I picked:

[D]8/2B5/1p1p4/1PkP1p2/P4P2/5P2/1p6/bK6 w - -

bm Bd8; id "exercise 04.12";

This one looks quite hard, and has a nice false solution to lure unsuspecting
programs :-)
1.a5 is tempting, but after 1.a5 Kxb5 (bxa5 2.b6) neither capture looks
sufficient to win since the black king can stop the single passed pawn, and the
white king is tied down.  eg:  2.Bxb6 Ka6 3.Bc7 Kb5 4.Bxd6 Kxa5 5.Be5 Kb6 which
seems to hold.


[D]8/8/5P1k/8/2K5/pr2r3/4R3/2R5 w - -
bm f7; id "exercise 07.08";

Quite easy this one, but nice cutes variations eg:
1.f7 Kg7 2.f8=Q Kxf8 3.Rf1+ Ke7 4.Rfe1 +-

I'm still looking for some good rook endgames (K+R+pawns vs K+R+pawns).

cheers,
Peter
