The more I play the game the more I understand that luck is a big part of the game, even if you have the best hand preflop, flop, turn, you can still loose on the river. Additionaly people playing cards that you do not expect them to be playing like 2 8 offsuit and doing a pot size raise from early position you are holding pocket As flop hits and it is a,2,8 he bets big you bet all in, and they hit the 2 or 8 on the river and take your chips. I chalk most things up to luck most of the time unless I have the nuts.
