OTB I knew my TP was ~ 15.8% so if I could become quite certain that I had more than 16% here, I would take. I have an extremely efficient position for 44 pips and my opp's 34 pips is clearly less efficient with a possible 4 gap and checkers on his lower points. Initially I though I could penalize him 3 pips and that would likely give me a close take AtS noting that 37 pips vs a very efficient 42 is a bare money take.

But upon further reflection, I really couldn't see how Joe's position could be expected to waste 3 more pips than mine. Two pips wastage seemed about right so 36 to 44 and I am every bit of 3 pips from a bare money take. So if 36 to 41 would be aboit 22% CPW, then being 3 pips worse than that clearly had to give me less than 15% so I passed not even being sure that I had 14% here.
