Bubble Play with KK

To expand a bit:

I don't play just to limp into the money. I want to make the top 5 (which is usually where the good money is).

The money already in the pot is almost half your stack, so taking it down represents a big win.

The TAG has apparently seen the limper fold in a situation like this before, so could be doing this with any decent hand.

There is a total of one hand you're truly afraid of: AA, but any flop with an Ace is bad news.

There is no reason to let the Villain see the flop without being pot committed ahead of time. He needs to out-flop you, not the reverse.
