First of all. I don´t play MTT or any kind of very big field tournaments, so do the HU match  ever start with both player having like over 100 big blinds, or most of them are just two guys with 25bb trying to avoid getting the first dominated ace? If it´s common for the HU to have effective stacks of over 100bb, then I think it would be proper to learn deepstacks to try and have and edge over the opposition.If it´s just too rare for the HU to begin with very big effective stacks, I believe there isn´t much of a point for me to learn deep stacks, since I don´t particularly like or dislike either. Thanks.
