My flaw costs me a huge pot(a case for checkraising)

[lautzutao]

My lack of checkraising in multiway pots is a huge flaw in my game, and here it cost me dearly. I figured I'd just post this hand as an example to those that share this common problem.

I'm 100% sure that a bet would have been placed to my left had I checked this flop, and could have more than likely have chased out at least the big blind, making him possibly call 3 cold seeing the action that ensued my bet.

I wanted to scream when I saw the results, but realized it was my fault the pot was lost. Live and learn I guess...
