Just busted this tourney. The chip leader was ok and pretty active as people were playing very tight.
Here are my notes on him:
opened for pot on button w aces
min bet turn and river with weakish hand opp
I debated just flatting seeing a flop and making a decision or repotting for value, as he was chip leader.
I think we are ahead of his range here. Whats your line preflop at this point in a tourney with these stack sizes? Play it safe and live to flop another day
