In the video it says we need to continue 80% of the time if we are getting 4:1. Isn't the actual frequency 20%?. If 80 is right, it kind of contradicts with the numbers in ep 2 where you say we need to continue 1/3 when getting 2:1.
hi great question and i am sorry i missed this earlier.
pre-river non-all-in spots create different math than river spots. hand equities are not finalized, stacks remain to be played, nobody is ensured a showdown, etc. remember that balance means indifference to our opponent's action - a balanced play offers our opponent no action better than another. we calculate this based on the odds we lay our opponent.
when we 3bet to pot, we're usually risking 1:2 and laying our opponent 2:1. in a normal pot bet spot, we lay ourselves 1:1 and lay 2:1, but raising pot requires us to wager double what is in the pot to win what is in the pot. thus, we get two fractions that appear to be 1/3 - our opponent, facing a pot bet, needs to 'win' 1/3 the time, and our range breaks even immediately if we get caught 1/3 of the time.
with the smallish raise in the AK hand our opponent laid himself better than 1:1 and laid us 4:1. that is, if this were a balanced river raise, he would have approximately 80% value and 20% bluffs. i'm having a hard time thinking how to paint this better than - nobody is really balanced here. i talked about it in the video: why raise the turn on a dry board with a value hand? why raise anything in position with these stacks? it just reeks of trying to force a specific action, which is the definition of unbalanced, since balance has no preference.
as far as how often we need to continue - this is where showdown v pre-showdown action is confusing. at showdown, a balanced range is indifferent to call/fold. pre-showdown, hand equities fluctuate enough that this is fairly tough to construct. recall how i talked about hands functioning as both bluffs and value in the same spot (small pocket pairs that 3bet).
at showdown, our opponent wouldn't care how often we called if he were balanced. pre-showdown, if our ranges were polarized to 'value' hands and zero equity bluffs, we would likely prefer a fold, since our value hands could only get worse and our zero equity bluffs could not improve - thus on the whole our range gets worse and worse. we 'balance' this by having bluffs with equity to compensate for the damage our value hands suffer on some runouts - we basically look to protect our range on various runouts: either our value hands are still strong or our semibluffs have become stronger. in essence, we're trying to be able to represent something on all/most runouts.
i think in the video i probably talked a bit too much about how often we should worry about calling here to avoid being exploited. avoiding exploitation should be your goal when your opponent is slightly unbalanced (toward exploiting you in a way which you cannot predict - if you knew how your opponent would exploit you, he wouldn't be able to do it!). in reality, i think this opponent is heavily unbalanced here to the point that protecting ourselves from exploitation is the wrong approach to this spot. instead, we should look to own him. we would do this by basically never folding a value hand and jamming all of our airballs.
is this unbalanced? of course. as i've said throughout this series, balance is a starting point we'd like to draw in the sand so we can calculate how unbalanced we can be!
