Converting 2nd places into 1st places - x-posted in STT forum

[rOCKeMdEAD]

Help required from some of you more experienced players. Below are the figures since I started making proper notes of my STT play. I realise that these are such a tiny sample that they cannot be definitive of my true results but I think they are fairly indicitive of my results prior to starting to keep stats. So can we take them as true figures for the purpose of this posting.

I play 6 seater tournies only + micro limit NL Cash games. I had reasonable results at 10 seater Limit STT but have stopped playing those through bordemn. I'm a tight aggressive player but i'ts not unknown for me to loosen up and switch between.

The problem I have is the heads-up part of the tourny. Of the second places below I can think of perhaps half a dozen where I went in to HU with maybe 60% (4000) of the chips at about the 400 BB mark and managed to lose.
Problem is I can't see why. (***) It feels as though I'm hitting a run of rags as soon as it's HU and having to fold the first x hands. Problem is that the opponent is then nearing my stack and then thinks I'm weak and starts leaning on me. I end up all-in on something only half decent out of frustration and end up getting called and busted. (*** this is the bit that I need you psychologists to advise on)

I realise this is a very loose question but how do I lay the law down early on HU and how do I do it against the different styles of opponent?

If anyone can give me advice on converting any of the lower results (3rd into 2nd) or can spot any holes in my stats then it'd be very much appreciated.

Can I just re-iterate that I think the figures below are pretty close to the mark with respect to my previous results.

Cheers guys,
