Hey,

I'd like to know how raise sizing is calculated based on %.
I haven't been able to find the answer on the Internet. There are threads on how to calculate POT size bet but that's now what I want.

When I was watching a Twitch streamer yesterday, I noticed this:

UTG open raised 2.5bb
POT was 4 bb
HERO raised 75% and the raise was 7.4bb
How?

Another situation:

HJ open raised 2bb
POT was 3.5bb
HERO raised 75% and the raise was 6.1bb
How?

First hero has to call the 2.5BB bet, so the pot becomes 4bb + 2.5bb = 6.5bb
Than he raises 75% pot, which is 0.75 * 6.5 = 4.9bb

So, he puts 4.9bb additionally over the 2.5bb, which becomes 7.4bb.

There are two strategy articles that cover the pot-sized raise:
https://www.pokerstrategy.com/strategy/various-poker/calculate-pot-size-raise/
https://www.pokerstrategy.com/strategy/sss/calcule-pot-size-raise/

They both say much the same thing, but cover the situation where more than one player has bet ahead of you.
They calculate the "pot-sized raise" and I assume that 3/4 of that value would be the 75% under discussion.

I'll check it out today if I play.
