# Descriptions of an elite mind

My starting part discerns the green from white and blue and red;
I use it to describe myself, agree with what's been said.

My second part's an aurous lass, a symbol of a state,
dilemma of a Nordic prince, result that's almost great.

My third part is an old film of a manhunt really tense,
and it describes one kilo or a shirt that's not immense.

My fourth describes an ocean, or a colour, thoughts profound;
a voice that sounds impressive, something buried underground.

My fifth describes an ocean, or some music, thoughts of woe;
you look up on a cloudless day, and off to jail you go.

My whole describes a mind that really turned out quite elite;
to beat us at our own game was a truly monstrous feat.

Who am I?

• Beautiful rhyme! Reminds me of a @HughMeyers riddle! DVL17 $\color{darkorange}{\bigstar}$ :D Edit: Could you be Rot13(Nyoreg Rvafgrva? Na nantenz bs uvf anzr vf "ryvgr oenva arfg"). – Feeds Aug 29 '18 at 6:39
• Thanks @user477343! That guy does have some great rhymes. Won't spoil in comments, but the anagram is certainly apt :P – jafe Aug 29 '18 at 6:58
• @user477343 Wow. Now I'm even famous for riddles I didn't write. :-) – Hugh Meyers Aug 29 '18 at 7:50

You are

IBM Deep Blue

My starting part discerns the green from white and blue and red; I use it to describe myself, agree with what's been said.

I: The “eye” discerns colors. “I” = myself. “Aye” = agree

My second part's an aurous lass, a symbol of a state, dilemma of a Nordic prince, result that's almost great.

B: Bea Arthur was a Golden Girl. The beehive is the state symbol of Utah. Hamlet pondered, “To be or not to be”. “B”, as in a grade, is good not great.

My third part is an old film of a manhunt really tense, and it describes one kilo or a shirt that's not immense.

M: M is a movie involving a manhunt, the Roman numeral for one thousand, and abbreviation for medium.

My fourth describes an ocean, or a colour, thoughts profound; a voice that sounds impressive, something buried underground.

DEEP: can describe the ocean, colors, profound thoughts, voices, or underground things.

My fifth describes an ocean, or some music, thoughts of woe; you look up on a cloudless day, and off to jail you go.

BLUE: describes the ocean, music (“the blues”), sadness, the sky, and the police.

My whole describes a mind that really turned out quite elite; to beat us at our own game was a truly monstrous feat.

IBM DEEP BLUE was the first computer chess-playing system to win both a chess game and a chess match against a reigning world champion under regular time controls, beating Garry Kasparov and acheiving a milestone for AI.

• pretty great answer, what was your starting point on this one.. – Shahriar Mahmud Sajid Aug 29 '18 at 7:31
• 4th and 5th came to me pretty easily, which led me to the full answer. I had to work a little bit for some of the individual subclues, notably in the 2nd. – kayzeroshort Aug 29 '18 at 14:53
• This is correct. Nice work! – jafe Aug 30 '18 at 4:14
