I was playing FT in a live tournament. I bluffed raised this guy and threw back my hoodie and took my sunglasses off and stared him down. I ended up seeing his hand he had 2 pair. With J928 showing. He bet 25K, into a 30K pot I snap raised him 75K I was holding 74 off. He thought for a minute or so after I was staring him down then decided to fold. I ended up getting 1st that night and that bluff was a big part. I saw his hand after I had made the action I did. So I wasn't enticed by seeing his cards.
I myself won by bluffing not so much, much more I won when I opened up other players of the bluff - I really love to do it ... This is one of the most beautiful moments - in live poker especially
I don't recall a specific big bluff win. However, for some reason I get more pleasure out of a bluff then a card showdown. It feels like i am really playing good poker when I get a bluff or two through during a poker session.
If you count making a stronger hand fold (as opposed to only pure bluffs with air), I won a little over a 120 BBs at a cash game. Had KK, opponent spiked an A on the turn but it was also a flush scare card and I got him to fold (and show) with a re-raise.
I won a 160BB pot in PLO where my opponent led for pot on the river on a non-paired 3flush board and I bluff raised all in over his bet with the Ace of the flush suit and he thought about it a bit but then folded. It's nice to know that your opponent can't have the nuts if you have that Ace and so it makes bluffing in that spot less nervewracking.
It depends because when you bluff your opponent folds so you can never really know if you actually buffed them or they missed what they were looking for.
I will talk about tournament hand. Was playing sunday million anniversary and totally represented my 75 as AK from the beggining. I do that from time to time. Won 44 big blinds bluffing of opponent with much higher stack.
