Hand against Toto Leonidas

[Defendant]

So, 3 days ago I went to the local casino to play some poker. Unfortunately the night was pretty slow, so all they had going was a 4-8 limit no foldem table, and a 2-5, 200$ buyin NL table. I got into the NL game after about 1 hour, and held my own, no major moves or anything. Two hours into the game, the seat to my left opens up, and a guy that looked real familiar sat down. Turns out, much to my dislike since hes sitting to the left of me, its Toto Leonidas (2003 US Poker Champion) on his way to Tunica, stopping by and wanting to mix it up some.
Of course, he sticks to his hyperaggressive game and just runs over the table left and right. After about 45 minutes of that, I am looking at a stack of about 225$ on the button, and its folded to me.

PREFLOP

I see As3s and try to make a play with a standard raise, raising it to 15. Right behind me, Toto makes it 30, BB folds. I thought he could be restealing here, but didnt want to chance a big bet preflop and opted to see a flop.

FLOP
