Felt like i'm getting overrun by bunch of strong regs this session. Had another spot vs very strong reg again btn vs bb.
i Had QJ spades and i opened to $125 bb 3 bets to $500 i call. $9000 effective stacks.

Flop is Ad Kh Qd, he bets $600 i call.
Turn is Qh he bets $2000 i call
River is 3c he bets $6000 and i'm puking all over the table.

This has to be the bottom of our range right? We have AQ/KQ and straights where we basically need to call alot here. Easy fold? What kind of bluffs can villain show up with? Thoughts pls
