I used to instruct on Tiger Moths at Cambridge and have approx 400 hours on type.
If you try and take off in the 3 point attitude you will get airborne in ground effect. There isn't sufficient thrust to overcome the drag and the aircraft will not accelerate. I've witnessed two accidents first hand where people failed to get the tail up and didn't abort the take off.....both aircraft crashed.
That said, the correct technique for all low powered tail wheel aircraft should be to raise the tail, however be cautious of propellor clearence. On higher powered types thrust can overcome drag and it is possible to take off in the 3 point attitude, however you probably won't see we're you're going and a bump (assuming you're on grass ) could get you airborne prematurely. ie below Vs.
Lastly when opening the throttle, do so progressively while maintaining directional control before moving the control column forwards.....
I hope that's of some help.
