Amanaplan, correct. Which is why i asked for a range. I would have shown a sample of a decision tree process applying frequencies. But im not going to spoonfeed. OP will at least need to type out a range.
Everyone else, this is a feally easy check for me otr. There are a number of reasons why, but the top reasons are:
1) a "buy-in" bet at 2/5 is a really, really large bet and people make very big folds to these bets. I know bc i bluff with this sizing ($300-$400) often. This is not 1/2 and this is not a $180 shove. People are very relative when it comes to amount of $ in this regard. However, once facing a check they somehow have an easier time shoveling it in. I dont know why. They just do.
2) its really hard for us to have any bluffs at all when we 3 barrel in live poker. This is because of the low fold equity, high multiway, shortstacked action we face. Its just impossible to 3 barrel bluff most of the time if you are game selecting well. So we will have more check/folds otr. Because of that, i like to have some sort of semblance of balance to my check/give ups. Strong one pair hands are perfect candidates in this regard. Im not talking about hardcore balance im talking about even the cocktail waitress knowing you are never bluffing here which means you should try another line that can max value.
3) people do not think AT ALL about what cards are good and bad to bluff. I actually hate typing this out bc its one of the few things that hasnt changed since 2010. They also dont value bet thin which makes river check calls really easy.
I just recently played a hand vs. a straight forward tag where i bet bet checked on 3
5
6
A
3
with 99 and he shoveled it in with missed hearts as planned.
Its just a really standard line for me and they still stuff everytime.
