Not sure how to play with 77/88 with 20b stack vs an early position raise.
We can't flat call as we don't have enough implied odds to set mine with only 20bb stack. There will most probably be couple of overcards on the flop and we would keep guessing once villain cbets.
I think 3bet shoving is a bit spewy vs a tight early position raising range. We are never getting called by worse.
Should we fold?
