Dealer: ** Hand [ 97748946 ] started ** I did not know why i loos this hand?
The game type you played here is Omaha (is not the same as Hold’em), in Omaha you must (and can only) use 2 of your hand cards and 3 community cards for making your hand.
More info about Omaha (and other game types) you find on page “Getting Started”
In this hand you had only a pair of Ks (you can only use 2 of your hand cards) and the winner had a straight.
Hope this helps. Greetings Happiness.
