Unknown villain. I open and BU call. We flop nuts with no redraw on very tricky flop. WIth tricky I mean that huge amount of turns change nuts. So I got idea that perhaps x-r is not bad approach. If villain check we keep pot smaller and if he bets I can then go for pretty committing x-r. Villain being short stacked helps on this. Also in player pool checks on this spot are very unbalanced so most of time BU is not facing x-r which might make stab decently high frequency. Though as said no reads.
If I remember anything from mastermind I believe this should be more of bet in gto because we unblock sets and two pairs. But then again I think in reality lot of sets and top two will actually bet here versus check.
every 5,6,7,8,9,T,J and Q. I do not have any backup.
