Ethics and EV of some plays for a house man?????

[bigsooner]

1) 7 handed 1 2 blind pot limit, I am a 25% partner in this game, BB thinks he is under the gun tosses his cards but they get nowhere near the center so e gets them back all fold to me on the button and SB folds out of turn, I raise to 10 (max raise at this point), with 94. =EV??? Ethical???

As luck would have it he called???? and flop came k94 turn 4 river 6 and he called big bets the whole way.



2) Is it ethical and or +EV for a house man to play more loose and aggresive on some situations to help the rake??? thanks
