What is a magnificent post?
Black's Knight has a magnificent post.

[Michael Farthing]

post means the same as position (or in the case of chess, the square where the knight is placed). In this context the knight is probably on a safe and well defended square (maybe it's defended by a pawn) from which it cannot be easily dislodged (probably no pawn can be moved to attack it) and will be attacking a good range of important other squares, probably inside the enemy's part of the board.

What's the verb for
to put out your hand to try and catch or get something
?

[IM Jack Rudd]

There are four verbs in that phrase, but "put out" is the main one.

[Mike Truran]

I think Soheil probably means is there a single verb to describe the phrase "to quickly...... something".

"Stretch out" probably does the job.

[soheil_hooshdaran]

No, I mean putting out your hand to try to catch, but just not quick and sudden.

[Mike Truran]

That's what it means.

"the be pawn" doesn't make sense. Please check the original quotation.

Sorry, "the pawn".

Is that his book on endings? I expect it makes sense in its context. What would occupy d7?
