What would you suggest when trying to use and study a 1 flop cbet size strategy?

In the past I ran 4 different scripts, each with 1 flop sizing then compared the evs for each board between them to get an idea which single sizes were useful on different boards.

It is very time consuming so wondering if you had a better way of doing this as you seem to like the simplistic approach as well and stick to 1 single size on flops.

Also if I wanted to practice these single size cbet strategies in the trainer not sure how useful the 3 sizes would be as pio will often split the flop range between them.

Thanks for the help

Hey Zefa I need a little more context to give you an answer here

Doing so should have lead you to realise EV's tend to be really close in SRP's.

I would recommend to run a single sim with all the sizes to a high accuracy, and then aggregate. It gives similar results to what you did, in less time. Your report should give you a great macro understanding of which boards require what sizing in no time.

Also if I wanted to practice these single size cbet strategies in the trainer not sure how useful the 3 sizes would be as pio will often split the flop range between them.

Yes, but isn't that the case for reality, too? We should look to study situations that emulate reality. e.g. we should study how to face a flop cbet when OOP in a SRP, not how to do so specifically vs 1/3p

Thanks for the help

This is great! I sometimes get too stuck with my mind "playing against a certain sizing" without realizing nobody is playing like pio and develop a general gameplan on certain board texture is more important than knowing how to play vs certain sizings.

It's a small thing but could be a huge mental blockage when studying, thanks for pointing this out!

Thanks for the detailed reply.
For a bit more context, I am basically doing more work on 200bbs and looking to work on studying oop 3b pots so i am wanting to figure out best cbet sizes for different boards. Was not sure if my old approach of running so many sims was the best way to do it or not.
When you say aggregate, you just mean comparing the ev of each bet size in the single sim? That would be much more helpful then running so many sims, I just didn't know how accurate the results would be compared to running an individual sim with 1 size only.
As for the trainer I agree facing multiple sizes is very useful and more like reality.

No worries mate. Yeah, we should always tailor our gameplays to be suitable vs HUMANS, not robots :P

Single sim with mutliple bet sizes → aggregating in excel comparing the frequencies, not EV's. This will give you a great macro understanding of what is going on, as you'll very quickly be able to identify which boards bet big and small, and which boards check a lot vs range bet.

That would be much more helpful then running so many sims, I just didn't know how accurate the results would be compared to running an individual sim with 1 size only.

So long as the right bet sizes are used, it'll be accurate. The quickest (and ultimately best imo) way to find the correct bet sizes is to run the single sim with multiple sizes. For OOP 3BP 200bb, 33/50/75/115 should be sufficient. Note the the 115 for 200bb, not 100bb.

As for the trainer I agree facing multiple sizes is very useful and more like reality.

Absolutely, yeah. Another added perk of doing it this way

Wow you actually share everything. what a move.
Someone studying poker for the first time would be pretty good at just watching a few of your video.

Ofc!

Yeah, that was one of the aims when making this :), esp. those who are newish to studying, not completely new

Excellent pio introduction! Thanks for doing that.

As gto wizard becomes more robust in its abilities, do you feel pio will start to take a backseat to it?

Thanks!

SoundSpeed Thanks mate!

If GTOw offers everything PIO does, in a fraction of the time, then PIO will definitely take a backseat/become superseded. Until then, there are still very clear benefits to having PIO (as a standalone product, or in addition to GTOw, dependant on user's preference). e.g. creating your own sim library. Note that if GTOw did so, it would likely kill off their future revenue stream, as users could build a library in no time and then cancel their subscription.

Personally, I invested into two simming machines this year for PIO.

Thanks!

Welcome as always!

Hey Luke thanks for the video!

You mentioned that in theory IP doesn't want to have merged bet OTR since it prevents IP from realizing all marginal equity for free. Just curious what's the threshold here? Is b50 considering an okay river sizing or we only want to do b66/b75 or bigger?

I only size down to b50 in smaller SPR's/MW. Otherwise I make a hard cap at b70+. This isn't GTO, just my approach. Plenty of good players include b50. Basically no elite regs find smaller unless they're exploiting/it's a very exceptional situation. If I were you, I'd make things more simple and say b70+

Hey Luke thanks for the video!

Welcome as always :)

At 43.00 you went with original PIO algorithm rather than PIOCFR. The PIOCFR is the fastest algorithm, but uses more RAM. I think it also produces more accurate results at high degrees of desired accuracy.
The (updated) original PIO algorithm is slower (even though it's ~2x the speed of the original PIO algorithm in PIO version 1), but uses less RAM. I think it is only included in case you want to run a sim and don't have enough RAM to run it with the PIO_CFR.
