i don't calcalate this in my head sheets explains it much betterin at pro poker school which is free to join and has about twenty video but the best ones are sheets on advanced hold-em. i have created a spread sheet that does this for me. the concept that i was trying to explain is that you always should be putting your opponent on arange of hands. by doing that you can find your
equity in the hand if you push. its based on the poss of hand combination and what you stand to win. i see if i can break the math down a lil better but what sheets calls it is if your goin to put your chips in the middle and you wantto know if your making the profitable play based on your opponents range of hands.
the very first thing to know is their is 1326 poss hand combinations to make.
then next thing you have to due is put your opponents on a range of hands in the example above i did that and subtracted one AQs because that is what we hold so that is one less poss hand our opponents can get.
once you have the hand range you divide that by 1326 which is every poss combination. hand range/1326=percentage that the opponent will have on of those hands
the second thing to do is calculate the percentage that your opponents will fold based on the hand range. you have to subtract your above percentage from 1 and then multiply to the power of remaining players to act. (1-%of hand range)^players left to act=percentage that the table is goin to fold based on hand range and number of players left to act
the last thing you do is you take your stack that your pushing all in with and add that to whats in the middle, this is what you stand to win if everyone fold. you then take that total win amount and multiply by percentage that table folds and that will give you your equity in your hand. (your stack+pot)X% calculated from 2nd step
i'll use the example from above and go through all the math only we will say we are 8 handed on the button and its been folded around with only the blinds left to act. we have 50,000 and blinds are 2,000,4,000 with 500 ante. so before any action their is 10,000 in the pot 1/5th of our stack.
71/1326=0.0535
(1-.0535)^2=0.895
(10,000+50,000)x0.895=53,751.7
and as long as our final number is greater then our starting stack it is a profitable play in the long run.
based on this theory it doesn't matter what our hand is because we are calculating our equity in the hand based on an opponents hand range for them to fold. i dont know if this helps in the explanation i deffinently recomend joining pro poker school for free its a great site and where else can you watch sheets break down advanced concepts like this for free. and to answer do most player do this the answer is no but alot of the top online mtt players who do this as their job, do. which is why you sometimes see top players push all in with 62off and get called, thier are using their position and hand ranges from their opponents from the information that have tracked and then making the best profitable play sometimes their wrong which is why you see that 62off but most of the time their are right because by their calculations it is a profitable play in the long run which is all they car about. the cards will always even out for everybody so the ones who can capatalize on better situations and extract more money are going to rise above the rest. but the best thing about this is if your wondering is it more profiatable to push or raise then you will get your answer by doing this math.
