Split or not?

Player1- Kc, Ah
Player2- Ks, 4d

Flop- Kd, Kh, 9d, 9c, 3h

Full House for both ..

If best of five wins then its a "split" right
Or does Player 1 win with the Ace kicker

Thanks

It's a split

Yup, sure is a split.

Ace doesnt feature as a kicker because its not in the best five card hand.

This is the best hand KKK99. No other cards matter in this example.

thanks guys
