Hello Guys,
I started to study PLO a couple of days ago, and I've some doubts about this hand.

Hand converted by PokerTracker 4

Hero (BTN): $2.21

BB: $1.14 (VPIP: 50.00, PFR: 0.00, 3Bet Preflop: 0.00, Hands: 4)
UTG: $2.14 (VPIP: 35.71, PFR: 0.00, 3Bet Preflop: 0.00, Hands: 28)
MP: $1.34 (VPIP: -, PFR: -, 3Bet Preflop: -, Hands: 1)

BB checks, MP checks, CO bets $0.16, Hero raises to $0.64, fold, fold, CO raises to $1.43 and is all-in, Hero calls $0.79

Notes:
Ad5d6c5c --- Equity % = 41.1363% --- Wins Hi % = 41.1147%
QQ**,99**,22**,Kd[Kd-],((Q9,Q2,92)!(QQ,99,22)) --- Equity % = 58.8638% --- Wins Hi % = 58.8422%
Required equity = price of calling / (pot size + price of calling)
0.79/2.24+0.79 => 0.79/3 = 0.26 => 26%

Questions:

1- Is it ok the PreFlop call??
2- on the Flop, I should have raised All In?
3- what do you think about the range that I thought the villain has?
4- the Required Equity is ok in order to call the Flop reraise?

please let me know if I miss something!
Thanks guys!
