peeling HU to a single open is pretty bad imo.
I would be 3betting ONLY vs active 4betters with a view to 5bet jam. 3Betting vs low 4bet's or low fold to 3bets is bad as well because these small pairs flop pretty poorly in general, terrible visibility, almost impossible to fully realise or protect your equity without flopping a set and in order to continue you're going to end up bluff catching with the bottom of your range vs villains who can aoften play near perfect vs you.
Not sure I'm 100% understanding you here Dave.Bearing in mind you may not have enough history on a player...
Peeling = Bad. (most likely flop badly/get outplayed post flop)
3 bet into unknown 4 bettor...is potentially v bad
So do we...
Fold
or
Take the initiative, hold our balls n shove???
imo. Peeling = bad, 3betting without knowledge of how our oppon reacts to 3bets = DEFO bad, folding = Never bad
If i 3bet here, it's almmost entirely because I'm planning to 5bet jam
