I assume yr not near bubble?
The nearer you are to the bubble then the tougher the call, obviously. The larger your skill advantage then the tougher the call also, but the blinds seem very high here so yr skill advantage won't mean a lot. If the bubble is far off then you can look at it pretty much in terms of chip equity.
Did the chip leader call with just you to act behind, or a few people to act behind? The more players behind him, the stronger his range is, obv.
Also you didn't say if you were playing 9/10 or whatever-handed.
9 handed, if blinds are not involved, then you're getting an interesting price. Your 3.5k + 18.5 + 18.5 + 2.7 = 43,200-15,000 in a 3-way pot. You have a hand. You'll have a commanding stack of 58,200 if you win. On the chips you need an equity of (15/58.2=) 25.8% for the win.
Lets errr on the conservative side and round that up to 27%. Lets say you need a bit more to call because you have a skill advantage and/or the bubble is a few tables away. If you were playing with total donkeys and you were near the bubble, then you would need much more equity to call, something like 35% or more. Now look at a couple of break even points:-
i) if the first shove is light, and has a range of any pair, any ace, any two face cards, plus some good suited connectors, AQo has more than 27% when the big stack has worse than 99+,AJs+,KQs,AQo+
ii) if the first shove is stronger, and has a range of 77+, A9o+, A8s+, QJs+, KJo+, AQo has more than 27% when the big stack has worse than:- 88+, ATs+, AJo+
Calling here with AQo is a real stretch against the average player. If either of these players are at all tight its a clear fold. You need one of them to be loose as a mudflap before you can entertain calling.
Nice post - thanks.
Not near the bubble - about 80 left (205 runners).
10 handed and chipleader was 2 to my right.
No real information on chipleader as he only moved to the table a few hands earlier. Original shove was from semi-loose player and as he was also shortish stack I put him on a range of any ace, any pair, any 2 pictures, suited connectors.
