What does a chess player need?

Why would you assume it's only 3 qualities? And why would you assume one quality makes no room for the other? Can't chess players need all three and more at the same time?

yes i agree with you - people have different opinion on different things. that was my opinion
1) If you agree with me, then it means you don't agree with yourself.
2) I haven't asked what was your opinion, or if the opinion belongs to you. I asked some other questions and you didn't answer.

A chess player needs different skills for playing and also for improving. In addition to chess specific skills, all of the general skills necessary for competitive play are required, as well as many skills that help learning.
Between common chess sense, book knowledge and experience I think common chess sense is most important, then experience. But there are many more skills that benefit a chess player, and it will be very hard to list them all.
a)Common sense?
b)Knowledge of book openings?
c)Experience?
d) Fighting Spirit.

good one but i want answers from the options

a)Common sense?
b)Knowledge of book openings?
c)Experience?
d) Fighting Spirit.
Fighting spririt is sumthing which not only chess players but everone should have

I'll have to go with experience....Then we can assume a player can use that to his advantage and forsee possible options. Assuming with this experience he or she is learning all the aspects of the game. As for common sense, well once both players use common sense....we have a draw

SRamakrishnan, it would be good if you also write what do you think a chess player needs so that a discussion may arise, or give some context, because the question is too broad. Otherwise the topic will turn into something like a comprehensive school lesson, where a teacher sequentially declines her no-cognizent pupils' guesses to a question she gave them to mull over, until the bell rings.
v.) a 64-squared board
w.) 2 kings
x.) 2 queens
y.) 4 bishops
z.) sod that, a chess set. Why do I even bother?
Hopnestly though, I'd say out of all of it, experience is the most important. Experience encompasses the other two options; experience lets you remember what reply you find works with you against, say, 1.e4 or 1...e5. Common sense doesn't really work that well, as it is common sense to say that the queen is more valuable than the knight...but experience will tell you, "ITS A DEFLECTION FOR A BACK RANK CHECKMATE".Knowledge of chess openings will help you prepare against fools mate, or telling you why g4-f3/4 is not a good idea, and when getting more advanced, experience still counts for a lot.
So of all of them, experience.

1) Energy/Enthusiasm to get critiqued and identify the what/why of the mistakes one makes in his/her games.
2)Not repeat the same mistakes discovered by (1).
Simply performing 1+2 consistently explains why a strong-willed average-intelligence human who just visits chess clubs and plays and learns from stronger players CAN become a strong chess player WAY FASTER than a high-IQ lazy person who owns a ton of chess books (or a chess.com account :)) but doesn't want to apply this self-correcting behavior (either because of complacency or just plain arrogance)
a)Common sense?
b)Knowledge of book openings?
c)Experience?
