There's a bit of a "scandal" going on right now involving poker training tools, but at the moment it's mostly confined to arguing between rival training services and poker lab nerds.
However, I feel it's interesting enough to delve into, so I'll do my best to explain what's going on here, in simple language.
There are various pieces of poker training software out there, which have the capability of analyzing actual hands and advising what is the recommended play. This is actually quite useful, and is a much better learning experience than simply watching others' hands and attempting to apply it to your actual play later. With this, you get a GTO (game theory optimal) software product critiquing your actual play.
This eventually evolved into "GTO calculator" software which can analyze your REAL TIME play, so you don't have to go back to it hours later to remember the hand and your thought process. Unfortunately, this has the tremendous potential for abuse. If the software is analyzing your hands as you play them live, then it can advise you the best way to play them before you act, thus becoming equivalent to using a bot to play for you!
The developers of these types of software came up with a fair compromise to the situation of potential cheating. Many software packages instituted a delay in the analysis of hands entered in "real time", thus making it impossible to use the software to make live decisions for you. This has been the case for several years.
Rory Young is the founder of Prometheus Poker and Odin Poker. Odin's website now brags, "Instant Solutions! No delay. NEW!"
Some in the poker community are understandably furious with Rory Young, and his blatant promotion of a real-time solver, which even amateurs can use to play like super-experts. It wasn't always like this. Rory once had a delay in Odin, but it has recently been removed.
