While we're all busy arguing about set play let's not forget #5. It was previously stated that cont bets are most beginning player's biggest leaks. This is a major problem, but I think the biggest and worst thing a beginning player learns is the word variance.

Variance is the crutch of denial that bad players lean on and use as excuse not to review play and find faults in one's play. Who here can honestly admit they haven't told a buddy they're being hit huge by variance because of suckouts that were paid off after the guy hit them, etc, etc. I'm sure you guys see where I'm going with this. I think this was your best point, Lukie.
