Just looked at this. It's a really simple fold, as you obviously now know. The one thing to note is that to play High Low games well you have to get used to a powerhouse hand on the flop turning to complete dust on the turn. It happens more in High Low games than High Only games, and you have to learn to not even feel any regret about it.
However... tbh your hand is not quite as amazing as you think on this flop. You have no low draw at all and this means that you actually don't dominate anything sensible (and even plenty of non-sensible stuff) that your opponent may wish to continue with on the flop. Even a filthy hand like K247 has over 40% equity vs your hand. Now change the 7 to either an A or 6 and you are even a slight dog. Note that I am not saying you have a 'bad' hand on the flop... I am just saying that it is not the powerhouse that you perhaps think it is. Yes it looks sexy, but the absence of a low draw really makes a big difference to the equities.
Yeah, I've run lots of equities, pretty fun when there are a hundred different combinations. Got them in a spreadsheet for future referral too.
