C⊗;
     In the help text below, $ means either dollar sign or altmode,
and ↑ means either ASCII or bucky bit CONTROL.  Note that on PTYs
and non-displays, the ↑B command must either be entered as αB or
as ↑←↑B, since ↑B is interpreted as "hold".

     ↑C followed by REENTER tells the program to quit thinking and
do an implicit PN command.

     The file commands in the MIT version currently do not exist.
If there is enough of a demand for them I will implement them.

     Enter moves in algebraic notation, e.g. E2E4 or B2B1=Q.  (In
algebraic notation white castles king-side by E1G1, etc.) or in
english notation e.g. P-K4 or P/K2-K4 or KP-K4, O-O for castling
kingside, X or * for captures, e.g.  NXB, promotion by =, e.g.
P-N8=N.  Terminate moves by space or cr if in english notation.
Rubout flushes previous typein, echoes as "?".  Acceptance of
move or non-typing command is confirmed by backarrow.

     In move typeout e.g. " 1 W E2-E4 3 0 0.5 IN 1.6" the "1" is
the move number, the "W" (white) is the side moving, E2-E4 is the
move in algebraic notation, the "3" is the maximum depth setting,
the "0" is the value return from TECH II's point of view (-100 =
TECH II is a pawn down) the "0.5" is the run time of the last
search (at depth 3), and the 1.6 is the total real time for all
searches made for this move (if in tournament mode, (set by $T)
it will be the time for searches at depths 1, 2, and 3).

	List of commands

PW	Play white.
PB	Play black.
PS	Play self.
PN	Play neither side.

↑R	Resets board to initial position, clears clock, does a "PN".
↑U	Takes back a move, does a "PN".
↑B	Prints board.
↑E	Causes program to make a move.
↑P	Print principal variation of last search.
↑W	Print statistics of last search.
		LMM	legal moves made during search.
		ILM	illegal moves made, and immediately taken back.
		TRM	terminal nodes in tree.
		LMG	legal moves generations.
		ICH	calls to routine which checks for check.
		PSM	moves made up to set depth.
		STV	captures made after set depth.
		FED	replies to check made after set depth.
	Sum of PSM ("plausible moves"), STV ("static evaluator moves"),
	and FED ("feedovers") equals LMM.
		LMS	legal moves per second of run time.

$C	$C<n>,<nmoves>,<nmin>, sets time control N to NMOVES
	in NMIN minutes total time from start of game.  N may be
	0 to 6.  Time controls must be in ascending order, and a
	margin of about three times the mean time per move should
	be left or else TECH II may overstep on its last move.
	T.C. 0 is assembled as 2 moves in zero seconds for book
	purposes and is normally not to be changed.  Default
	settings of T.C.'s are 1 move/minute, good for hacker
	games.

$A	$A <maxtim>,<mintim>,<mintim2>, sets the parameters which
	control use of the active schema in tournament mode.
	MAXTIM is the number of minutes after which to abort the
	active search, MINTIM is the minimum number of seconds
	per move which must be left in order not to abort the
	active search, and MINTIM2 is the minimum number of
	seconds per move which must be left to start an active
	search.

$D	$D<integer>, where <integer> is of the form ZZYYXXDD, the
	letters representing digits, leaves tournament mode, and
	sets four search parameters from <integer>.  DD is the
	(weighted) depth up to which the search examines all
	moves at each node.  Up to depth YY, safe active moves
	are examined, and all safe replies are considered at
	nodes following an active move, and all moves at depth
	YY+1 if the move from depth YY was active.  Safe checks
	are examined up to depth YY, and all checks from YY+1 to
	XX.  Safe captures are always examined, and after depth
	YY all captures are examined.  All replies to check are
	always examined.  Leading zeroes may be omitted in
	<integer>.  $D3050701 is roughly equivalent to, but much
	faster than, $D6 .

$T	Enter "tournament", or variable parameter mode.  If there
	is enough time per move left (see the $C and $A commands)
	for an active search, the "DD" parameter (see $D command)
	is set to one and a single active search is performed in
	accordance with the ZZ, YY, and XX parameters set by the
	last $D command.  Otherwise, or if the active search is
	aborted, the "XX" and "YY" parameters are set to zero and
	the program iteratively searches starting at the depth
	specified by the "DD" part of the last $D command and
	deepening by one with each iteration.  However, the
	iteration always begun at depth at least 2, and for the
	first 4 plies is begun at exactly 2 irrespective of the
	"DD" setting.  Suggested tournament settings are
	$D3050704 followed by $T, with appropriate $C and $A
	settings.

$S	Setup board.  Scan from queen-side to king-side, black's
	first rank first; e.g. $S 4BK3 8 8 8 8 8 8 4WK3←, where
	spaces and ← are typed by the program, sets up the kings
	in their original position.  At end of setup it will be
	white's turn to move and neither side will have castling
	or immediate en passant privileges.

$V	$V Prints game on TTY.

$?	Type this cruft.
