You raise in the HJ . . .

[Grisgra]

with T9s. The button 3-bets; he's taggy and will 3-bet here with almost any pocket pair, KJ+, and maybe the occasional suited connector or suited paint.

The flop comes KKT. If you call the flop/turn, you'll find the turn and river are complete blanks.

You . . . ?

Check/call down, hoping the river bet is a value-bet against your calling-stationy AQ?

Work in a donk somewhere, figuring you can fold to a raise? (But if there are just calls, what do you do on the river?)

?

(BTW, against an opp. like this on the button it may be a good reason to just fold T9s in the HJ, but let's assume you didn't wisely fold preflop . . . )
