I can't see folding to a lead-out on the first hand. Are you playing 99 purely for set value? Are you automatically giving villain credit for an 8? Second hand is tough. Without reads I might get scared off by the strange action (bet, minraise). I might just as soon put in a 2nd raise to find out where I am, but I don't think I'm looking to commit that many (500?) chips with this hand.
