Two Pair on board - kicker question

Big argument arose last night as we were playing at the kitchen table. Clarification?

Player 1 holds 6,9 (suits unimportant)
Player 2 holds A, 4

Board shows K,K, Q,Q,6

Here's the conflict:
Does Player 1 or Player 2 win?

Player 1 maintains that the 6 he holds pairs the 6 on the board
Player 2 argues that the Ace is the kicker, since the two best pairs are on the board.

player 2 is right. only the best 5 cards count

Player 1 has K K Q Q 9
Player 2 has K K Q Q A

the answer is always the best five card hand, in all situations. doesn't matter whether you're talking about a flush, or four of a kind (say the board has four of a kind - your kicker matters!)

Thanks. I knew I was right. Sorry to post such a lame question. You guys are great.[/i]
