# Most of this file is the automatically generated result summary from
# my tablebase building program which was used to produce the 4piece
# endgame tables which are used by my program ascp.
# Lines starting with a # are comments.
# Positions that I have looked at in some detail and found to be interesting
# I have commented on, but there are more than I have had time for.

# Some positions which are marked as >100 ply deep wins are actually
# draws under the fics 50 move rule.  Too bad.
# Some positions which are marked as draws are only draws under the FICS
# rule that stalemate with equal pieces is drawn.

#NEW : by clicking on a link you can open a window showing the position.
#For links to work, your 'popup window' browser option must be activated.

# Positions in this file are in FEN format which is the format used by
# winboard/xboard to save positions and also some sort of standard.
# To view a fen position on FICS ie. fen:8/8/8/3B4/7k/8/8/8 w - - 0 1

# I use distance to win rather than distance to conversion to avoid
# trading down from a short win to a longer win with less pieces.
# ie. with distance to conversion my program would sac from a RRRvK pos
# that is won in 16 ply to a RRvK that is won in 20 ply then down to a
# R vs K that is won in 30 ply!

# The percentages reported are the percent of positions actually stored.
# This may not be the same as the percentage for all possible positions
# including redundant ones.  This is most noticeable in positions with
# bishops on both sides, as there may be more positions stored with the
# black bishop on white squares than on black squares.
# I only bother to mention this because I spent an hour or so trying to
# figure out why my program was claiming <50% draws in B vs B when I could
# easily see that there had to be >50% draws for all possible positions.

# Two knights cannot beat two kings without some miracle.

# See diagram.
# This one is long indeed! The manoeuvre by the white knights
# seems to be unique (apart from possible repetitions).
# 1.Nec4! or of course the symmetrical 1.Ned3. 1...Kf6
# 2.Ne3! Qf8! 2...Kg7? would lose immediately to 3.Nd3.
# 3.Nbd1! This knight is heading for g3. 3...Kf7 4.Ng2!
# And this one for e2. 4...Kf6 5.Nf2! Kf7! Better than
# 5...Qf7 6.Ne1! Qf8 7.Nf3 Kf7 8.Nd4 and wins. 6.Nf4!
# Now 6.Ne1? failed to 6...Qb8! 6...Kf6 7.Ne2! Qf7!
# This time not 7...Kf7 8.Nd4! 8.Nh1! Qf8 9.Ng3 Kf7 10.Nc1!
# This knight must move to prepare the final combination, but
# c1 is its only square: 10.Nc3? Qe8! or 10.Ng1? Qd8! 10...Kf6
# 11.Nf5! Kxf5 12.Ne2! Kf6 13.Ng3 Kf7 14.Nh5! and wins!

# See diagram.
# Precision seems to be required by White to stop Black
# from promoting all three pawns and reaching a winning
# 3 pieces v king ending.
# 1.Kb1? f1N 2.Kb2 f2! leads to Zugzwang. Black
# to play would lose immediately (3...e1K 4.Kc3), but White
# to play must run either into 3.Kb1 Nd2! 4.Ka1 Nb3
# 5.Kb1 Na1 6.Kxa1 e1B, either into 3.Ka2 Nh2! 4.Kb1 Nf3
# 5.Kb2 f1B soon followed by promotion of the last pawn.
# So White must play 1.Kb2! f1N 2.Kb1 Nd2 Now this is the
# only move, as 2...f2 loses to 3.Kb2! and 2...e1K/B to 3.Kc1!
# 3.Ka1 Ne4 3...Nb3 4.Kb1 Na1? 5.Kxa1 e1B 6.Kb2 now
# leads to defeat. 4.Kb1 f2 Promotions are still impossible,
# and 4...Nd2 only repeats. 5.Kb2! Nc3 6.Kxc3 e1R This
# would win if the pawn was still on f3, but with the pawn
# on f2 White has an unexpected resource. 7.Kd4! Rb1
# 8.Kd3! Ra1 Black can't promote: 8...f1R? 9.Kd2! 9.Kd2 Rc1
# 10.Kxc1 f1K/B draw.

# The BvNNN ending is normally won for the bishop. The winning
# plan is to attack one of the knights while the two others lie on
# squares of the same colour, thus unable to sacrifice themselves
# on the two next moves.
# Some positions exist where the bishop loses, either by being
# immediately dominated by the knights, either in a more subtle
# way (see the second diagram).

# non-trivial draw, no pieces ever get sacced
# See diagram
# But how can this ending be drawn? Only by making use of the
# two exceptional wins with NvB. In this position, after any move
# by White, say 1.Bf5, Black can answer 1...Nf3!! and set up
# a fortress, because Black can attack neither of the knights
# without running into one NvB win:
# 2.Be6? (or any other way to attack Nc4) 2...Ng3! 3.Bxc4 Nf1
# 4.Bxf1 Nh2! wins.
# 2.Be4? (or any other way to attack Nf3) 2...Nc3! 3.Bxf3 Nd1
# 4.Bxd1 Nd6! wins.
# Moreover, the bishop is neither able to dominate all knights, neither
# to attack Ne2 without attacking one of the two others knights on
# the same diagonal. Hence nothing can stop Black from moving back
# and forth to his "fortress" position.
# Subsequent computer research by Ben Nye has shown that there are
# exactly six such fortresses for the white knights. Here are they:
# Nc4,Ne2,Nf3 (the one used here)
# Nd3,Ne4,Nf3
# Nd3,Ne2,Nf3
# Nd3,Nf3,Nf1
# Nd3,Nf3,Nh1
# Nd3,Nf3,Nf5
# You will find a further example of this ending in my page of
# studies found by computer, where you will find out why Nc4,Nf3,Nh1
# is not a fortress.
