25/50NL HU >300BB Deep Tough River Spot

[optionsguy]

nasty spot. aren't we going to see a flopped straight here a lot of the time? i think with you 3-betting the flop and checking the turn i don't think he can put you on a flush and i would think he would lead the river with a hand better than ours with the river being an A because we would be very likely to call a "bluff" and probably check down anything worse.
