Hero raises to $2
Player 2 calls $2
Player 3 calls $2

Pot: $6.20

Reads:
Player 2 likely has some kind of drawing hand, suited or unsuited connectors or 1-gap connectors anywhere from KQ down to 56, or a mid to low pocket pair. Unlikely to be
slow playing a monster pair.

Player 3 probably has either an AK-A9, or pocket pair below QQ. With QQ or better I would expect a re-raise from this player.

Hero bets $9.00 and is all-in
