When i raise with these preflop and do not get a caller i feel a massive failure, aside from the obvious feeling of a missed opportunity.

But my question is this: Is it better to get 3/4 callers and bet smaller rather than risk raising too high and getting no callers at all? I normally raise 4x's the BB, especially if someone has already limped. Is 3x's just too small letting them in too cheaply? What is the +EV strategy?

Thanks

PS-I play 6 max on Ladbrokes and will adjust my raises to the players and flow of the table
