PF: Limp is fine given the table conditions.

Flop: I think a fold would be better here. The pot isn't that large yet. You might already be behind to a better king, any ace, and your tens could be reverse dominated. And you don't know if there's going to be raising or re-raising behind you.

Turn: Raise it up while they're still drawing. There are straight draws and flush draws out there, and if another ace comes on the river you're likely to lose to a bigger FH.
