Button is tight, no other reads. Am I making a serious leak by calling here despite my 12-card wrap draw? My default play is always call as the chance that I will fill my straight is 1.22 to 1 and the pot is giving 2 to 1 (therefore, in my head, I am getting good odds). But then I suddenly realised, due to the stack sizes, a flop call pretty much commits me to call a turn bet if the board is unpaired. That means if I call all the way to the river, the pot is giving me an effective pot odds of approximately 1 to 1!! (which would make the original flop call wrong!)

If I'm wrong with the play of this hand and this call, that means I must have leaked lots of money in the past and I should seriously consider giving this game up. I suspect that I have misunderstood a fundamental concept of the game.

The question is, is the flop call wrong?
