This is a discussion on Hands review within the online poker forums, in the Poker Software & Tools section; I usually see players on Twitch that mark hands for later review.
I'm never sure what this exactly means. On the first place, what software would
You can use a HUD to tag a hand for review, for example in PT4 you left-click the tag icon and scroll down to the hand you wish to tag. Then you can make a hand review report showing all tagged hands. Then, you can open a hand details or in a replayer and review it.
When you review a hand, you step through all your actions and ask yourself if they were correct, and try to spot mistakes that are leaks that you should fix in your game.
The basic way to look at each spot is "is this the most +EV action in this spot with this specific hand in a Vacuum?", and this is the correct way to play vs. bad players. The more advanced way (which is necessary to deal with competent regs and unknowns), is to consider your entire range in each spot, as in "what other hands will I do the same with?".
Thanks I will try to implement this and see what software can help me, will look into PT4 (I believe it's paid software) maybe they have some trial period.
I don't play that much like to justify buying some license for this, but I want to slowly try to make my game better and I think reviewing hands can help a lot.
