Like open raising 4xBB in HU SNGs

[betgo]

I have found I get better results open raising 4xBB from the SB/button than raising 2-3xBB. I generally raise 4xBB half the time, and a mix of 3xBB, 2xBB, limping, and folding the rest. I find the 4xBB puts pressure on my opponent and makes good use of preflop initiative and postflop position. I can make a smaller raise for various reasons or just to mix things up, and it is hard for my opponents to know if I am doing it because I want action or have a marginal hand.
