We have just sat down at the final table, however I knew the villan from the previous table. He was very agressive but usually showed down decent hands

ShnellShnell will be using his time bank for this hand.

As you can see I took a bit of time on this one - the reasons for this are ...
1 Villan was usually raising with med / high PPs, AK, AQ possibly AJ - My gut feeling was it would be a coin flip.
2 Villans chip stack is the 2nd largest at the table and would put me back in the pack if I lost, At present I have a big chip lead.

So question - Do you call?

Is it better to keep my current chip lead, or risk it on a coin flip for a bigger chip lead.
With my current stack I am confident I can bully and run the table so is it worth risking losing this lead for the chance of complete domination.

Fold that one.

You got a great stack, keep it for stealing blinds.

You want to be the one raising all-in with AK, not calling the all-in. Lay this one down and wait your turn.

You friend sounds like one of those people that believe you have to try to win every single hand no matter the circumstances. Once you get it in your head that you don't and that it's sometimes OK to fold the best hand, you're on your way to being a successful tournament player.

The next step is being able to fold QQ+ preflop.

I folded QQ the other day for the first time. I play at the low $$$ tournies so usually it just isn't an option, but it was early, only one read on a super tag, who i'd only seen raise once in 2 different tourneys. He pushed, had a caller, and another all in behind. Felt great when they showed AA and KK and JJ.
