Borgata 1K, facing open limp from button

[wpr101]

I have about 34k in chips. Blinds are 1k/2k with 300 antes; note the large antes. A big stack recently got moved to the table and he's raised maybe 2-3 hands in the past 2 orbits. Nothing abnormal from him. Anways I'm in the BB with A5s, villian as described limps from the button. SB who has me covered completes... I'm not too worried though because SB is probably completing any 2 and raising good hands. I push. Do you like it?
