Hello,

Pokersnowie recommends doing that when opening the SB for 3 bb and facing a 3-Bet for 9 bb (the green hands are the ones Snowie wants to min 4-Bet) :

Usually I think there are pros and cons to Snowie's preflop strategy, but the one thing I think Snowie does well is measure the EV of its hands, and the interesting thing about BVB when facing a 3-Bet is that Snowie thinks the EV of min 4-Betting is worth far more EV than calling or 4-Betting bigger (just 4-Betting to 23 bb rather than 18 decreases the EV of every hand significantly).

E.g. 55 when facing a 3-Bet gives that result (just a random example, same thing applies to every hand Snowie chooses to min 4-Bet) :

1) Has anyone tested that strategy and if so how good is it in practice?
2) Does anyone know why Snowie thinks min 4-Betting is worth so much more than any other move (sure that puts the opponents hands like J8o in an awkward situation but the difference in EV is truly gigantic)?

Thank you for reading, any answer/thought would be appreciated.
