bet sizing - later streets (turn + river)

[fine to slow play flop as long as we make up for it on later streets]

nuts/ nut blocker - you should seriously consider a geometric bet on the turn, no matter how large. If they fold, you probably wouldn’t have won much anyway. When the reward for winning the maximum is so large, that reward is worth pursuing at the expense of missing out on the occasional smaller bet from weaker hands.

The only time extreme, multi-street slow-playing really makes sense is when you block a lot of the hands likely to pay off large bets (e.g. top set blocking TP combos). In those cases, it makes sense to hunt for smaller game with less ambitious bets.

GTO rarely uses a geometric strategy before the turn, as ranges are too close and equity too dynamic. Equities crystalize on later streets and ranges become more polar, incentivizing geometric bet sizes. When equities run much closer and can shift more easily on early streets, this is not the case.
