Back when I 1st watched this, I thought it was a very interesting ICM spot for Dvoress. Ran some sims, using HRC and Pio...
Assuming DD was using a 100% Limp strat in the SB (which isn't a stretch at all imo) the most interesting/crucial decision is whether to LRR (3bet) or just call. The $EV for calling ($15,190) is higher than 3betting ($12,246.) HRC advocates a mixed strat (calling 12% and 3betting 88%.) Not sure why it doesn't want to just call more frequently?
Here's the Limp-Calling Range*:
*HRC calling ranges seem way too wide, so a lot of the weaker combos can just be folded since we only have to defend ~50% (of our 90% limping range) vs a 3.8x iso. Notice QQ is being called 24% as well.
Here's the LRR/3Bet Range:
The main issue with LRR AKo is it allows BB to 4bet jam all of his AKo and make $29,929. We can't call off all our AKo combos, since calling the 4bet loses -$11,056. HRC has AKo calling off at 36% freq. See 4Bet Calling Range:
As played River: Pio Sim using the ICM option and HRC Ranges:
AKo is a pretty low freq bluff-catcher (~25%) so DD might have thought Vogelsang was over-bluffing this spot, or he was just unfortunate to roll low (on his RNG) and Call.
