You don't need to be fancy to beat this level. Cure your FPS now please.

Hand 1: Fold to flop raise. DO NOT go broke on that turn with TP? That is a SUPER wet board, let it go man!
Hand 2: B/F that semi-wet flop, try to buy yourself a free river with your OESD...
Hand 3: Assuming you meant an 80/30, I raise PF a LOT more, like $2.50-$3, then try to get it in on the flop without being tricky. Turn Check-Raise is bad with A-high against this player.
