yoh're allowed to get bluffed from time to time :-P
This! If you never get bluffed you're calling waaaaay too much.
Havent we called Flop/Turn to call river?
Nah, we've called to improve or get to showdown. Obviously after just calling flop and turn our hand doesn't look superstrong and villain does look quite strong, giving him the opportunity to bluff lots, but we will have a few stronger hands in our range than this, including some rivered flushes, and we need a good reason to believe villain will triple here, rather than the other way round. We ofc don't beat any of his value range.
