Boring standard spot, $200 NL

[djj6835]

Don't have an actual hand history but this has been happening a lot lately. Assume villain is basically unknown but is probably bad, 30/10/2 type stats over a smallish sample with no real reads. I used to autoraise these river bets but they seemed to call a lot so I stopped. Now a suddenly a bunch of players have started taking this line again.

100 BBs effective

Hero is button with TJ and raises $7 BB calls.

Flop is Q 6 2 rainbow. Hero bets $11 BB calls.

Turn is is a 4, completes rainbow board, check, check.

River is a 9, villain bets $12, Hero is annoyed.

Maybe people are suddenly just good at flopping top pair I don't know.
