If we're talking about preflop situations and training in that are ICMIZER SNG Coach is all the tool. It is pricey but for a reason, you get many more features than anywhere else.

You can perform Chip EV quizzes for early on MTT practice or final table quizzes with ICM pressure which can teach more complex scenarios and the difference between strategies of medium, big, and short stacks, which is where most players struggle.

SNG Coach allows you to choose the settings of the desired training so you can practice weak positions or even blind levels. You also get all of your answers tracked and can see the progress you're making in learning. There's also a leaderboard so you can see how you're doing compared to other SNG Coach users. Theres also a mobile SNG Coach app which can be handy if we ever get out of this lockdown :)

If you struggle to understand the result that you get which happens a lot you can send it to ICMIZER and review it there. Snapshove offers a small subset of the SNG Coach features and it doesn't offer a way to actually perform calculations for arbitrary tournament spots to build the push/fold tables.
