After my post on Wild and Wonderful Walls, I got
to thinking more about flat count. More specifically, I got to
thinking about the cost versus potential benefit for each move (in
flat count terms). I am not
trying to reduce the game to flat count concerns only. But, since
flats are what make
roads and flats are
also the determining factor when awarding a full board win or a
material depletion win, it is important to realize that each move you
make has a flat count cost and needs to pay for itself over the
course of the game. For example: Your opponent decides to capture in
order to contest a position on the board and you respond in kind,
creating a stack. To create this stack, each of you paid flats, in
hopes of a decent return on investment...or, at the very least, to
keep the stored flat energy away from your opponent (For he who
controls the stacks…).
Below, I have attempted to chart the Immediate
Flat Count Differential (IFCD) cost/benefit for each basic move in
Tak, as well as a projected Future Potential Flat Count
Differential (FPFCD). Italics are needed because many times immediate
threats leave you unwilling or unable to utilize the stored power of
your stacks. Potential can also be dampened by your opponent’s well
placed walls or capstones.
If you are playing
Takticianbot, you will notice how well it spends its flats. It tries
to deplete its Reserve Pieces Remaining (RPR) as fast as humanly
(computerly?) possible, only making moves that lessen the IFCD if
they have great FPFCD or block or mitigate your FPFCD. You must spend
your flats in the same Scrooge McDuck manner or you will lose...every
time.
---Addendum---
Thanks to comments on r/tak by Bismuthsnake, I realized that I didn't really tell you how to use this chart (oops). And, also, I am changing the FPFCD to include the reasonable response of your opponent to place a flat (-1 to each FPFCD).
So, as to how to use this chart...If you were considering a move: find that move on the chart below, weigh the cost vs potential benefit in flat count, compare that to the strategic value (I don't know how to put a numeric value on this (ask TakticianBot)), and then proceed with play.
If you see an easy response (other than flat placement which is now included in the chart below) by your opponent, let's say a recapture of the contested stack, look at the chart and find their potential move, reverse the sign of the differential, and compare it to your current proposed move.
Formula would look something like this: Potential move (IFCD + FPFCD) - Opponent's potential response (IFCD + FPFCD) = net flat count gain/loss.
Also, keep in mind RPR and, in general, if you are ahead in flat count, lean towards moves that deplete your RPR. **See sectenor/Turing's excellent blog on End Game for more on this.

Higher numbers are usually only seen when teaching or playing
inexperienced Takkers (or some of Takticianbot’s ruthless finishing
moves).
I
calculated the highest possible FPFCD by using an edge-bound stack
without obstacles and opponent’s flats covering the linear path of
the stack run-out.
This
chart seems to back up these currently held Tak theories:
1.
The basis of your Tak strategies should rely on flatstone
placement. Flats are the only piece that can be played that both
adds to your flat count and also depletes your reserve. And, since
both are desirable, the foundation of your game should be to place
relevant flats as much as possible.
2.
Single captures and simple movement (without capture)
should be avoided unless there is a clear board advantage given to
you by the move. Single
captures only give you a +1 IFCD, do not offer any ROI (-1 to 0 FPFCD) and
do not deplete any RPR.
3.
Capturing your own pieces should be avoided unless there is a
clear board advantage given to you by the move. Capturing
your own stack (usually with a Wall or Capstone) should only be done
to protect said stack from your opponent, make a robust Tak threat,
or as part of a long, devious strategy.
4.
Stacks are powerful; but, they are also a big liability.
Stacks are inevitable in intermediate level play and above. Stacks
have a the huge potential to swing the flat count for or against you.
They also are the only entities in the game that can make threats
more than 1 square away from themselves. But, they can be stolen away
from you in the blink of an eye and leave you wondering how you ended
up like Ozymandias. This is why you see most large, relevant stacks
controlled by a wall or capstone...an attempt to keep control of
them. And I’ll say it
again for all you Frank Herbert fans... He
who controls the stacks...
I realize that more advanced players have learned all (or most) of
this through experience (or through coding bots). But, let me know
what you think and what I might have missed.
