Size Hunter

You can't learn from multiple bet sizes. You can from one.
At the table you only ever use one size. A multi-size tree splits every frequency across sizes, so there's nothing you can actually learn. All hold'em study has to start from a single size. Editing the tree in Pio yourself, deleting sizes and re-solving? Tedious, and easy to get wrong. Size Hunter does that step for you: drop in a multi-size save and get back the single-size optimal tree, ready to open in Pio as usual.

Why it has to be a single size

Multiple sizes teach you nothing

Solving with five or six sizes gets closer to the theoretical value; it was never meant for a human to study. Each node's frequency is split across sizes, 33% here, 25% there. You can't memorise it and you can't use it at the table. An evening of study and nothing sticks.

A single size is where learning starts

At the table you use one size. First work out which size each node should use and how often, then you can talk about strategy. All hold'em study should begin from a single size; multiple sizes come later.

Doing it in Pio yourself? Painful

Edit the tree settings, remove sizes, re-solve, check the strategy hasn't drifted. An hour or two per tree; nobody gets through a hundred. Remove the wrong size and the whole tree changes character, and you won't know by how much.

Size Hunter gives you the optimal answer

Drop in a multi-size save and it picks the best single size at every node, keeping the result nearly lossless against the original. What comes out is a single-size tree you can study straight away. Queue dozens or hundreds of saves and let it run.

What you need

A Windows PC

Windows 10 / 11, 64-bit. No installer: unzip and run, no runtime to install. More RAM helps on big trees; 32 GB or more is recommended.

Your own PioSOLVER

The software does its computation through the activated PioSOLVER 2 or 3 on your PC; PioSOLVER is not included. It finds your Pio installation automatically, or you can point it there manually. Results produced with Pio3 open in Pio3.

FAQ

Which saves are supported?

Flop and turn saves from PioSOLVER 2 and 3. The output is in the format of whichever Pio version did the processing.

Does the strategy get worse with a single size?

Not noticeably. When deciding which size to keep at each node the software checks the effect on the whole tree and keeps the loss tiny. That's the difference from just switching sizes off by hand.

What if I change computers?

Unbind the old PC under My account and generate a code for the new one. One license can be bound to 2 computers at once, with 2 rebinds per year.

How long does it take?

Depends on the tree and your PC: small trees take tens of seconds, large trees with thousands of turn nodes take ten minutes to half an hour. Batch runs can be left unattended.

Can I use it without PioSOLVER?

No. The software does no solving itself; all computation is done by your own PioSOLVER, so you need a working copy first.

How do I get updates?

Sign in to My account and download the latest version any time. Unzip over the old one; your activation is unaffected.
