KK No Limit Question

[Scottnyce]

$50 NL table. Blinds are $1-$1

I just sit down with $50.

I get KK in big blind

2 callers, then a player in Middle position raises it to $5. ALl fold to me, I raise $10 to make it a total of $16 I put in the pot. All fold, MP player calls.

Flop.

A 10 J

I bet out $10. MP player goes all in (he has me covered).

Do I lay them down?
