A few years ago, some very smart guys generated some GTO strategies specifically for winner take all (WTA) jam or fold (JOF) situations. I used these tables to pretty good success in live WSOP satellites and online hyper-turbos.

Learning them is a pain, though.

I wrote an app to simply give me a hand and stack and position, and quiz me on jamming (or calling) or folding was correct. I cleaned it up a little bit and have published it on the Play store.

Click here to download Joffrey, a simple Jam Or Fold trainer (get it? JOFfrey? ).

I found it helpful to practice situations and improve my JOF brain quickly. It sure beats memorizing tables.

Enjoy, and let me know if you have any feature suggestions or bugs or anything annoying like that.
