Aside the queen which piece is the most important to you and why? 

the king is #1  then the queen as they are the 2 most powerfull, then rooks, bishops...

a-pawn i gotta have that a-pawn

my knight, so that I can attack 2 pieces at once!

 Thats true dont you think the king hardly attacks?

 i feel you manlike the queen and the castle at the same time and checking the king as well right. nice day man.

 more explanations required.thanks though.

The king, for reasons of survival

nice point.

Between knights and bishops theres little to choose between them but bishops are better in an endgame (knights at the start where positions can be closed.) 

I like knights because they can jump over pieces, (I started playing chess at a young age so this has always being a favourite part of the game for me,) you can set up knight forks, they can attack a queen, without the queen attacking the knight back. 

That said I still value bishops more than knights as at the end of the game they can get to any square on the board in the bishops colour in only two moves. 

 i agree with you.friend just that i differ on value i ithink i will go for the knight.
