personally I think you have to go with whatever works for you I can understand both arguments and during the games I noted certain behaviours by various individuals which I tried to exploit provided the situation fitted similar criteria.
Likewise when on the button I sometimes showed my hand when raising because I wanted to keep people honest (much to the annoyance of my team captain drowslasher who doesnt believe in showing his hand) because Myfair who was the BB when I was the button I knew was good enough to spot steals on the button so showing AK when raising on the button was in my interest, that said I didnt do it everytime I had a good hand on the button either because otherwise id be giving away a likewise tell.
This is only my 4th tournament within APAT and even I noticed there are some familiar faces showing up again and again at the FT so these people obviously have a style that works and itd be boring if we all played the same style so sometimes what seems to be a bonehead play is actually fairly smart.
Let put it this way if Gus Hansen makes that play he is a genius , if me , you or mayfair try it were donkeys
