Oop semibluff late in NL $109

[HelixTrix]

Sorry, but I can't get the hand history converter to work today so I'll try to make it as neat as I can. I think I'm happy with this play but I have a feeling it will look donkish to a lot of people so I'm interested to hear opinions. I'll save talking about ranges and things until after some responses.
