Of course ther's some luck but I can't quantify it.
If you don't get the cards you lose.
I'm just a learning player.
I played four matches yesterday.
I was better than all four players but I went 2-2.
I was dominating the first player when my AA got cracked to QJ.
He calls the allin and flop came JJx - I'm done.
Next hand I get AKs go allin he calls with 33, it holds up match over.
Next match I'm severly damaged when my AA allin gets call by 97o.
Flop 68T - I'm Done.
I crush the next two players in our matches.
I don't feel too bad because that's Poker!
