blinds 2500-5000 ante 500, 6 players At the table
10500 in the pot
Villain is bb , cheap leader of a tourney with 500-600k chips, viewing hero as a good tag
Hero at SB A3o (122500 stack left,is average stack)
all fold,hero??

Would jam. You ll get 10 % of your Stack trough blinds. And you have enough Chances to get called by hands like kx qx which you lead.

This villain will call me 12-15% of hands if i shove and I have about 0 EV here,raising is bad too cause it is weak hand to play post flop, so what about limp?? And if he raise I shove?

As far as you are right with you 15 % calling, i calculatet your Overall equity:

Thinking of 100 Hands played. its 100 x 122500 invested equals 12250000 Chips.

85 % you winning your stack plus blinds and Antes back = 11305000.

Than thinking of his calling range of 15 % you have a winning Chance of 34,15 %.

So now beeing called 15 % is 122500 x2 plus blinds and Antes = 255500 x 15 ( being called 15 times). = 3832500. And you are winning 34 % of the time equals 1303050 winning.

So its 12250000 total Investment on the one site against -->11305000 (getting just blinds and Antes) plus 1303050 (winnings getting called) which gets 12608050 winnings.
so you are making 358050 Chips over 100.

Not much but still profitible.

Though it depends on where you are Standing in the tournament, thinking of icm.

Otherwise it depends on the villains fold to steal stats. if its high enough i would raise and fold if 3 betted. if is calling much, i would rather do call and flat a raise. a 3 o is **** oop but we can flop good enough to check call a handful Flops.

If villain is like most the population, then you can bet he is over-folding to a raise. So I would probably advise that and go like 2.5-3x. If you are unfortunately sat next to someone who isn't overfolding, and plays well post flop, then it's time to start limping.

Depends on type of player. If he is aggressive and you think he will raise a limp frequently, I think limp/jamming is great.

A bit big to open jam, if he's peeling a decent amount I think limp>raise because we are going to be playing OOP with a hand that plays like crap post.

Also not many people are overfolding in BB these days, especially when they are CL.

Villain is prob going to defend pretty wide. Raising and limping both have their merits.
