Straddling 3 handed

[Percula]

Many rooms will not allow a straddle when three handed.

I would not do it unless the other two players really are players. Most B&M players hate SH play, then add the extra pressure of a straddle every time they are out of position, you will be looking for a new game in short order.

From a strategy point of view, if the other players are up for it, then yes, every hand and raise often too.
