Ive tried it twice ever.

Once in a $5 turbo on Stars, randomly playing hands. Came 2nd somehow. Got HU and just pushed every hand. Had one lucky hand where i "felt" my cards, has A2 suited, and got all in in a 4 way pot and flopped A22

The other one was one hand in an MTT, to prove to someone for a bet i can read hands without seeing my own. I ended up putting them on their exact hand (i could still rebuy so it was worth it). I calld them for having a mid kickered Ace (they had A9).


As for the merge flip the cards around, i think thats for 2 people in one house playing and you dont want them to see your hand.
