The English Language

[soheil_hooshdaran]

Means ...because it is...?

[soheil_hooshdaran]

What's the difference between
...the plans that are typically followed...
and
...the plans that are usually followed...?

[MartinCarpenter]

Nothing.

[soheil_hooshdaran]

Why does he repeatedly say
enemy pieces
not
oppenent pieces?

[Matt Mackenzie]

Just that "enemy" sounds a bit more colourful and fits in with chess being a "game of war".

[soheil_hooshdaran]

"ponderous" is an insult?
Like ponderous Rok
In fact, they are actually rather ponderous creatures

[MartinCarpenter]

Slow, slothful etc.

[soheil_hooshdaran]

What's the difference between
blocking unit
and
blockading unit?
What does it mean that the oawn on e6 blocks f4-f5 and d4-d5?(There is Black pawns on c6 and g6 too)

[MartinCarpenter]

Nothing much, although conceivably a blockading piece is implied as being physically in the way more than a 'mere' blocking one would be.

With the e6 pawn, he just means that it is preventing white from playing those moves without adverse consequences.

[soheil_hooshdaran]

So why do you not call "preventive measures", "blocking measures"

[MartinCarpenter]

You can more or less. Like I've said a few times we like to have many more than one phrase to call everything!

[soheil_hooshdaran]

What's the diffe4rence betweern fixing, immobilizing, and blocking opponent pawns?

[Barry Sandercock]

No real difference.

[soheil_hooshdaran]

What about the imaginary (unreal) part?

N.B: Every complex number has a real part and an imaginary (unreal) part.

[John McKenna]

What Barry wrote is correct.

The language used only seems complex - fixing, immobilizing and blocking have no imaginary part in this case and really do have the same meaning.
