Looking at sizing in a std spot
MP: $1,879.97 (188 bb)
CO: $1,000 (100 bb)
BTN: $4,628.75 (462.9 bb)
Hero (SB): $959 (95.9 bb)
BB: $2,799.25 (279.9 bb)
UTG: $1,000 (100 bb)
Preflop: Hero is SB with <>
3 folds, BTN raises to $20, SB raises to $80, BB folds, BTN calls $60
Flop: ($170) 4c Th 4d (2 players)
(~$879 behind on flop or 5.17 psbs)
SB bets $90 (52.9% psb), BTN calls $90
Turn: ($350) 7h (2 players)
SB bets $170 (48.5% psb), BTN calls $170
River: ($690) 7d (2 players)
SB bets $619 and is all-in (89.7% psb), BTN calls $619.
=> With a completely polarized range one should bet equal fractions of the pot. In this case that would be ~62.3% of pot on every street or $106/$238/$535ai. (chen mathematics of poker)
Is our range completely polarized? No, if the board came out 222-blank-blank this would be much more the case. However, it is much closer to being polarized ranges on this board texture then others. And in 3bet pots ranges are pretty polarized in general.
A lot of opponents design their strategy to shove river for just under pot. There are many board textures where its advantageous to use this sizing, as it allows you to not define your range (as much) until later streets which is awesome. Most good players know if you are shoving for just under pot you need ~1 bluff for every 2 valuebets and people are pretty good at designing their ranges in this regard imo.
However, in 3bet pots usually you are using a strategy in which you are trying to threaten stacks and get all in by the river, so we are usually pretty polarized on a decent amount of boards. A lot of good players are going down in terms of their 3bet sizing on the flop (allowing cheaper bluffs for weaker part of their range) which seems to be in direct contradiction to a few spots where they may want to be very polarized and thus should bet equal fractions of pot on each street. Any thoughts? Sorry in advance if what I am trying to say comes across confusing.
