I've noticed that in several online tournaments I've played where I end up going all in pre-flop with the best of it I am getting outdrawn a minority of the time with consistancy.

To specify I've gotten into 5 heads up pre-flop all in situations. Some I've instigated some I've called. In all five occasions I've been a favorite with at worst 60/40 fav. up to 75/25 fav. I've lost on draw outs about 1.5 times for every five hands played in that scenario in the same session.

This has happened to me with regularity in 4 other almost identical separate tournament situations.

Question:
In a tourney situation when you win say three of these 75/25 fav. situations in a row should a guy be looking for the draw out on the fourth one? This has been troubling me as all of these situations are where I am in a double up or get crippled situation in the tournament. Specifically, if I have a good read on a guy and put him on an inferior hand say 75/25 fav. and he goes all in and it's up to me should I call that fourth time? Or does it make sense to throw the best hand away preflop and wait for a better play?

Hope I'm being clear here.
