Hey, sorry for the late reply, against this opponent who is a recreational i would probably just bet myself on river a lot as a bluff (with hands that lose to Ahi) expecting him to have mostly Ax folds. I do also think we could check jam as a bluff though here very often as again i suspect he's only really going to have 99 for value, honestly in this spot i think both lines are going to be super profitable and if anything i would probably bluff way too often here using hands like Axddhh that got here, i would also bluffcatch a lot too.

Thanks TRUEPOWER hope poker is going great for you. glgl at the tables

Hey, thanks for the kind words.

Yea you've basically nailed the adjustment in regular games, so without antes in a normal 6max game i would play a purely 4b/fold strategy against this size.

However on Coinpoker IP is supposed to use a larger sizing given the extra dead money and given the dead money we aren't facing as drastic pot odds so we ''should'' and i would, still have a calling range.

All that being said though most players do still struggle playing IP in 4BPs so i don't think defaulting to 4b/fold would actually harm your EV in reality and may actually overperform.

Thx for the quick reply and your assessment Paul, that's really helpful!

The point you raised about the pot odds changing in ante games certainly makes a lot of sense and dampens the effect of the large size. I don't want to add on to the discussion as your reply fully answered my question. But your comment inspired me to finally do some quick equity math that I always was too lazy to do before.

In case anyone's interesed here's what I attempted to do:
Motivation - I had the feeling that the change in raise size in common ante preflop charts was over-proportional compared to the pot odds effect introduced by the ante.

But I have to add that I always used a quite small 3x 3b in position in classic games and therefore always compared it to that in my mind. I know that there are a lot of players already using 3.2-3.5x even in classic non-ante games.

Some pot odd calcs (required equity):
Classic 6-max 2.5-7.5 pot odds: 5/(7.5+7.5+1.5) = 30.3% equity
0.7bb Ante ranges 2.5 - 7.5 pot odds: 5/(7.5+7.5+2.2) = 29.1% equity

Classic 6-max 2.5 - 9 pot odds 6.5/(9+9+1.5) = 33.3%
0.7bb Ante ranges 2.5 - 9 pot odds 6.5/(9+9+2.2) = 32.2% equity

In short, the pure required equity effect of the ante in a 2.5-7.5 scenario is about -1.2% (defend more)
The pure effect of switching from a 7.5 to a 9bb size in a classic setting is +3% (defend less)

Comparing non-ante 2.5-7.5 with ante 2.5-9 we need 1.9% more equity despite the ante.

In short, I had the feeling that the spread of these quite large 3b sizes was also influenced by GTOWizard spreading them in their sheets and even noticed some players going 9.5 or 10 these days - which is when I started experimenting with 4b/fold.

But I do understand that even in a 2.5-10bb setting a calling range is still +EV when executed well - it's just getting really narrow.
