I had an experience similar to this.It was on PS.Cash game.I had $15 on the table in 5c 10c game.
A new player joined the table.
I lost the whole $15 to the same player .Everytime I folded he folded.Every time I entered a pot whether I raised or limped,he entered the pot.
If I had a pair,he had a higher pair.If I had 2 pairs he had a higher 2 pairs.When I had a straight he had a higher straight.I even had a Q high flush and he got a 4 card A high flush.There was not even once when I had 2 pairs and he had a straight or I had a flush and he had a full house.He always had the same combination as I did but a better one.I think I was robbed !!!!!!!!!
