What type of End Game are Drawn?

Sanny, here are 2 useful exercises you can conduct to explore what are
called MAMS studies. [what you ask below you can get from almost any
beginning chess book]
I would like you to set up 2 positions, and see if your program can solve
them - they are called Kling&Horwitz Fortresses.
[for historical interest these positions went unsolved since 1851 - and
credit for challenging them goes to John Roycroft /Test Tube Chess/ 1972]
Evidently Timman understood this well enough, since the first GM win was
over Speelman 1992 Linares.
(A) this is the easy one - set up
White: Kd5, Ba4, Bf8
Black: Kb6, Nh1
that's easy, no? if too easy try the N on f2 - now, here comes the hard
one:
(B)
White: Kd7, Bb3, Bh6
Black: Ke5, Ne4
solve.
this (B) makes 'the fortress' which went unsolved for 150 years. [ if
anyone has another engine, try it, taking note of the number of moves
grin ]
Wow! Same amount as squares on a chessboard ;-)
