$5/10 5-handed. I have been card dead, and not very active generally, although I've picked up a few small pots by betting this image. An orbit or two ago, villain raised $30 in HJ and I reraised on the button to $90, he folded PF. I had garbage but he didn't know that. Villain was a younger guy, seemed relatively solid, but no real reads. Villian now in the button (has me covered) raises to $30. I call in BB with Ac9c and $1530 behind. Pot = $60 post-rake.
Flop comes Qc9d2c, giving me 2nd pair and nut flush draw. I check, button bets $60, I raise to $150. Button reluctantly calls after some thought. Pot $360.
Turn comes Kc giving me the nut flush. I lead for $300. Button thinks and calls. Pot is $960.
River comes 2h, pairing the board. I have $1050 left.
What range do you put the button on as the hand proceeds? What do you do on the river? Tx in advance
