Probably a set is the minimum you need to call a 5 bet shove but perhaps 67 is the absolute minimum
Did he have AK?
K9 actually (missed). I was thinking minimum set too.
If you did have 55, 66, 77 in that spot would you 4 bet the flop?
Happy to 4 bet definitely. Also happy with the call to the shove. $80 more to win about $130 is fine by me when I know I've at least got outs, may be ahead. If I've been done by an over set then it's just meh.
Prefer the 4 bet to the trappy flat as well cus I want to get the lot in with 2 cards to come if I happen to be behind.
