# Sample rcfile for Sjeng 11.x
#
# First number is size of hash table (transposition table) 
# An entry is about 16 bytes, and there are three tables, 
# so the total hash size is the number below times 48.
# Normal, Bughouse, Crazyhouse, Losers
#
100000
#
# Evaluation cache entries
# An entry is normally about 8 bytes
# Normal, Bughouse, Crazyhouse, Losers
#
4000
#
# Proofnumber search buffer
# In suicide/giveaway and losers Sjeng uses proofnumbersearch instead 
# of the more common alpha-beta search. If the buffer is filled
# Sjeng will have to stop searching. Make this a large
# number if you will play suicide or losers at slow timecontrols.
# You can safely set this to 0 if you do not play suicide/giveaway
# or losers.
# Each entry is about 28 bytes.
# Suicide/Giveaway and Losers only
#
500000
#
# Kingsafety scalefactor (range 0<->2.5)
# This controls how much emphasis Sjeng will
# put on kingattacks vs material gain.
# The eval can be completely finetuned below.
# Crazyhouse/bughouse only
#
1.0
#
# Development scaling (1=enabled/0=disabled)
# Sjeng will put less emphasis on trying to
# get pieces on good squares if it does not
# have much material in hand.
# Crazyhouse/bughouse only
1
#
# Razor drop moves (1=enabled/0=disabled)
# Sjeng will look less deep at
# drop moves that seem passive.
# Crazyhouse/bughouse only
1
#
# Cut drop moves (1=enabled/0=disabled)
# Sjeng will try to avoid looking at drop moves 
# where the dropped piece can be captured immediately.
# EXPERIMENTAL
# Crazyhouse/bughouse only
1
#
# Book learning
# Sjeng will adjust the openings it plays
# depending on the outcome of the game.
# All variants
1
#
# Futility pruning/Limited Razoring (1=enabled/0=disabled)
# Sjeng will try to avoid looking at positions
# where it is materially lost, or will look at
# them less deeply.
# All variants
1
#
# One-reply extension (1=enabled/0=disabeled)
# Sjeng will loop deeper at very forcing lines.
# This can cause Sjeng to see some tactics faster,
# but it may reduce overall search depth.
# Normal/Crazyhouse/Bughouse
1
#
# Recapture extension (1=enabled/0=disabled)
# Sjeng will treat a recapture like a forced move.
# Normal/Crazyhouse/Bughouse
1
#
# Use Smarteval (1=enabled/0=disabled)
# This enables the use of an evalution 
# which can detect some typical threats,
# but which will also slow the search down.
# Crazyhouse and Bughouse only
1
#
# Use Attackeval (1=enabled/0=disabled)
# Sjeng will do a full calculation of
# which squares near the king are threatened.
# This will increase its awareness of 
# kingsafety, but will also cause it
# to search slower, and hence look less deeply.
# Crazyhouse and Bughouse only

#
# Kingsafety (Crazyhouse/Bughouse only)
#
# The following tables are the 'tropisms'. 
# They are basically bonusses for having pieces
# close to the opposing king. The closer our
# pieces are, the better. First number is a 
# maximum distance of 1 file/rank. Second 2 etc...
#
# Pawn tropisms
40 20 10 3 1 1 0
# Bishop tropisms
50 25 15 5 2 2 2 
# Knight tropisms
50 70 35 10 2 1 0 
# Rook tropisms
50 40 15 5 1 1 0 
# Queen tropisms
100 60 20 5 2 0 0 
#
#
# KingAttacks table  (Crazyhouse/Bughouse only)
#
# The following table is used to give penalties
# depending on the number of squares around our
# king that are attacked, taking into account
# the pieces in our opponents hand.
#
# It is only used if AttackEval is also enabled
#
#
# Columns are the number of squares that are attacked.
# Rows are the number of points in the opponents hand.
