$1000 eff. I have Q♦ Q♥ in BB. V opens to $20 in UTG, 3 calls before it gets to me.

V is a hardcore recreational reg who I would describe as "not that bad" compared to the field. He can be agro - barreling his draws on multiple streets. He can be loose, I've seen him open UTG as loose as J9s. And he's able to make solid folds postflop / not pay off.

I 3b to $100, V thinks for a bit and calls, everyone else is out. Once V calls I'd range him as all PPs and AK.

Flop: 8♣ 7♠ 3c♥ Pot $262 I bet $130, V calls.
Turn: 2♠ Pot $522 I bet $250, V calls.
River: A♦ Pot $1022

1. I would appreciate feedback on all streets, especially sizing.
2. What do you do OTR and why?
