Misreading board in live game cost me $$

[Frond]

I've sort of done it playing live Omaha 8/ob. I sort of recall the hand: I had TTKx in the BB, flop came down KTx with 2 to a flush. Looked at my cards and figured I flopped the boat. I ended up pumping it and some guy called me all the way down with a flush and won. This was after I had been playing 08 for a while! Happens. I've done it in HE but not all the way to river.
