In his latest video, Gareth James talks about the potential issues you can run into when using pre-solved preflop solutions. Preflop solutions are great if everyone has the same stack size, but how often does that happen in a tournament?
In the video he discusses this spot where the button is on 30bb, the small blind is on 30bb and Hero is in the big blind with 15bb.
A lot of players in this spot will take a look at their stack size, pull up the 15bb charts (when they’re studying, of course) and go with the solution.
