I perfer just calling and wait till middle or late position raise if
the raise is medium size then just call.But if
some one raise big enough then you should go ahead and move
all-in.That way you can play head up and didnt risk much.
Playing aggressive at early position is a bad idea that you dont want to
scared the whole field and end up having no chips.
Slow play are really useful at this early stage making everybody think you only had the top pair or some sort of draw is like an illusion.
Who would of think you had a monster in your hand
