Which Hand Costs You the Most Money?

It depends on which position you're playing, the actions that were taken at the table, the stack size, the stage the tournament is at, these cards are played differently in each of these situations, I can make more money hiding my AK, just making a call, than 3-Betting with AA and everyone folding their hand.

For me it is pocket kings, I freaking hate them. To be honest they are tough hand to play. 1/3 of the time a ace come up and you never sure if your a head or not where say jacks 1 or 2 overs make them easy to fold.

Lately, I think for me it's 99.
It looks good when I see it in the pre-flop, but then the flop comes with bigger cards and I never feel very comfortable again 😅 Sometimes I don't know if I should continue betting or just give up.
It's a good hand, but I think I lose more with it than I should.

At Omaha, especially straight Omaha, definitely aces. At hold 'em when you lose with aces, you lose big. In one of the freerolls yesterday, I was busted out early with A9 - three of us all-in. The other two hands were aces and 10s. The 10s won.
