AlterWay is the second program in the Chess Puzzles
Series. It is aimed at developing heuristic and combinatory
thinking as well as at improving the skill of distributing
one's attention over the whole chessboard and taking
decisions under conditions of time deficit. In the practical
chess aspect the program helps consolidate knowledge
about the chess pieces (their movements and captures),
and trains the ability to make fast and accurate calculations;
of particular importance is the fact that the program
teaches to take note of available/prospective interaction
between/among pieces and make perfect use of it.
Pieces of both colours are involved in the game. You
play for one side (you can have any units except King
and pawns) and the computer plays for the other (the
opposing side can have any units except King). The choice
of the side you will play for is entirely up to you.
Any movements made on the board are your moves, the
computer only devises puzzling positions and passively
watches your actions, waiting for your error. Your task
is to capture all of the other side's pieces; but each
of your moves must be a capture. That is, no non-capturing
moves may be played.
If you succeed in capturing all of the opposing pieces,
you win. But if there arises a situation when no more
immediate captures can be played and on the chessboard
still remains at least one enemy piece, you lose. Besides,
you also lose when you have failed to perform the task
within the allotted time interval.
What can be easier than to capture all pieces, you
may say. However, that "simplicity" is deceptive.
Because in almost any situation you will be faced with
the possibility of not one but several seemingly alternative
captures. And in each of such situations you will have
to make a correct choice, deciding what to capture next
and what route to follow. Thus, you will not be able
to complete the task successfully unless you quickly
discover and execute an optimum sequence of captures.
But to do that will require much intellectual effort
on your part! In a lot of the tasks the goal can be
achieved in several ways, though. The optimality of
the route you have chosen is not evaluated by the program
and does not affect the result. You can capture any
one of the opponent's units by any one of your own units
(provided that the capture is legal). It is not necessary
to use all of the available units to eliminate the opponent's
army: if you have several pieces, and are able to capture
all enemy units using just one of them (e.g. a Queen),
still it is a victory for you.
The game has two modes: Play and Training. Play mode
incorporates 10 levels of difficulty. The difficulty
of a particular task is determined by the number of
enemy pieces you must capture, the number of pieces
at your disposal, and the time interval in which you
must cope with the task. The more pieces are on the
board, the more alternatives are available and hence
the harder is the task. All playing tasks are newly
generated by the program, their number being virtually
unlimited and the possibility of encountering the same
situation twice practically equalling zero. For each
task you have coped with the program gives you a certain
number of points. The higher the difficulty level, the
more points you get.
