On being lost

Following are some notes on “On Being Lost”. Some are genuine grammatical bloopers. Some are just me blathering on. The bits in square brackets are my suggestions, the rest is your text.

When playing a game of chess there was [were/was a multiplicity] usually multiple moves that I could make
lot of time losing [, maybe?] especially to
The team were [was/members were]already exhausted.
The chess equivalent of “my purpose is we’re here” and “will this move bring immediate benefits”. [Just don’t like this]
Since Sun Tzu had principally talk [talked] about military combat,
I questioned [asked?] how did anyone know if any of this was right?
Most saliently Ball’s Bluff is an abject [object!] lesson 
4,000 odd Greeks [looks nasty, and potentially ambiguous. How odd were those Greeks?. Probably should be “four thousand-odd” in words, or “around 4,000”, I don’t know]
There was a why of movement as in why defend here over there in much the same way that in a game of Chess that I will decide to move this chess piece over that. [sentence needs some punctuation]
Situational awareness, [“situational awareness and” not comma. Unless writing a US headline ;)]use of terrain and maps appeared to be vital techniques in the outcome of any conflict. 
I was out on a limb with nothing to back me up.[Mixed metaphor. Nothing wrong with it, if you like that sort of thing.]
I want you to now imagine [Split infinitive. Might upset rule-bound pedants.]
(i.e. there are eight Pawns) [You might need e.g. because this isn’t the only instance. e.g. there are two Knights]
repeatable forms of gameplay i.e. [e.g. — there are many repeatable forms] fool’s mate. 
[Just a suggestion: In this section, have a care for those who do not play, and have never played, chess. Try to steer clear of chess technicalities unless they are absolutely necessary convey the message. I don’t have a clue what “fool’s mate” is, nor am I inclined to find out.]
 i.e. the battle at hand. [That’s a hanging fragment of a sentence. I didn’t much like it but there’s no great harm in it]
This gave me six absolute basic elements … and movement. [Is movement really an absolute basic element of a map? Really? Even in the Ball’s Bluff example? It’s important to the use that the map is put to, granted …]
But climate is … also the opponent’s actions [Is it? Just asking.]
Hence I turned to [the] next factor 
Imagine a normal six sided dice[die “dice” is plural]
These are context specific as in [I’d prefer “in that they are” to “as in”, but it’s up to you] relevant to the battle at hand. 
In other words you don’t flank an opponent when an [the] opponent isn’t at the point you’re flanking. [I don’t have a clue what this means.]
But there are also many approaches that are not context specific but [are] more universally useful.
one group might provide suppressing fire whilst [I think while would be better here. Just personal choice. I prefer whilst for the “whereas” type meaning] the other group flanks [I still don’t know what this means] the opponent.
