Would need to have 5 time bigger bankroll than my opponent off course presuming that we are playing regular speed tournament.For example if he has 10000$ stack and i have 60000 i would easily call his all-in hand with any hand that i have.
What I understood from the question, I will respond as follows:
End of tournament, I have 20BB meeting any opponent 3BB or 4BB going ALL-IN I paid being the BB, with T9 Suit hands between other hands.
There are innumerable answers to your question, a player in TILT going ALL-IN all the time A9 I paid his ALL-IN.
Things that I would consider:
- How early/deep are we in this tournament?
-- Am I playing to win or playing to cash?
- Is it possible this player tilting?
- What position am I in this hand (i.e., who is after me)
Depending on the answer to all of those (which need to happen within 20 seconds probably if this is a MTT online) along with the hand that I have, that's how I would decide.
In a tournament I prefer not to CALL if someone with more than 40% of my chips goes ALL IN, instead if it is an All IN of another player that has a size less than 40% of my chips then I do CALL only if I am in last positions and if there are few players in that hand, with an acceptable hand.
Otherwise I prefer to keep my chips and play good hands only, at least until I get to the winning spots.
Calling all in preflop is a whole different game than calling all in post flop, regardless of chip stack advantage/disadvantage. Playing style of your opponent is also a big factor when deciding to call an all in.
But the general rule is: if you have the nuts or demi nuts, you should call.
I don't think it is so much about my chip advantage . I mainly consider the blind level and whether I can still play my style if I would lose the hand . But firstly I think about the villains range and whether I feel I'm ahead preflop . A coin flip is one thing , but going in way behind is another .
Calling all in preflop is always hard decision, no matter if you have AA or 7-2. Pre flop all in mostly going a gamblers not players and ussualy they have more luck than you and they crack your AA with theirs 7-2 getting 777 on the flop
