fold TPTK here?

[BigBiceps]

I raise the pot after 1 limper from early position with AK. limper and 2 other callers to the flop.

Flop: K 6 4 unsuited

I bet pot, then get raised the pot by the guy behind me. The others fold.

Do I call here, which is tantamount to going all-in?

I have no info. on the other player.

Results in white below:

Not sure how he cold called my raise preflop with that, but he won my stack. </font>
