never fold for one bet on the river in a big pot?

[private joker]

I had a very similar hand the other day. The street I misplayed is the turn, where I definitely should have raised. I had such a strong read that MP1 was full of crap that I had to blow away the field and make it heads-up to ensure my victory. Luckily my mistake didn't prove fatal, and although I still failed to improve, I called for one bet in a large pot.
