Given the table conditions i would estimate fedor is opening about 29% of the range
Then the nash equillibirum for shoving would look like this
I dropped some marginal equity hands from BB´s range and estimate that this is the BB´s jamming range perceived by Fedor. BB moved from shoving 23% in nash equillibrium to 20% in reality.
In the above picture we have Fedor´s calling equities against perceived BB´s jamming range.
I dropped A7s from fedors calling range as it is pretty marginal. We could also drop Kqo but my butfeel says he is more likely to call Kqo than A7s.
So given fedors calling range BB could be shoving something like this
I myself would cut off all the hands with a +0.16 or lower and get a 32.4% shoving range.
These calculations are pretty conservative from fedors side as im basically assuming fedor will give hero respect for not being too out of line.
I think hero can shove safely atleast the nash and very likely even wider. Maybe taking away only hands with +0.16 or lower is still somewhat loose but hero could be shoving somewhere between 23% to 30%
Comparing flatting to jamming
Q8s has 43% equity against fedors opening range
Total pot: 9 * (0.125) + 1 + 0.5 + 2.25 + 1.25 = 6.125
Hero needs to call 1.25 to win 6.125 so he is getting odds 1 : 4.9 (20% equity required)
R = 0.2 / 0.43 = 46.5%
Hero needs to realize his equity 46.5% of time to breakeven with Q8s.
In a BB vs BTN situation where button opens a 50% range then BB should realize about 50 – 75% equity. As CO is opening a 30% range i take a rough estimate that BB could realize about 50% equity post flop.
So the EV of flatting Q8s should be:
0.43 * 0.5 * ( 6.125) – 1.25 = 0.07BB
For comparison Q8s EV in
Nash equillibirum: -0.11BB
Fedor giving villain respect: +0.49BB
Though its very popular nowdays to have wide BB flatting ranges then maybe it is more profitable to use an all-in strategy for the first few times when hero is given some respect
