this is tru i had a pretty similar situation when a player lost their head and completely lost track of the math of the call.
i limp late with 89d flopped kd3dTd. all limped pot, i bet pot. 2 calls. turn comes Ac. i bet 25 (slight over bet by about 8 chips) at this point and here is the crucial part of the hand, i have 14 pounds in chips behind, was playing a suited connector strategy with all pairs (depending on relative stack size to a preflop raise).

so he takes a good 3 mins to call, i coax he mis reads and calls, he did question whether to raise (i wish). river comes Ah i shove my last in he CALLS!! i show flopped flush, he mucks then mutters something about another diamond coming....

i stove the hand later to realise that because 6 are gone he has a 14% chance of winning with the call and would require another £70 ish behind in my stack to pay off this call because the pot was about 45 and the call was 25 into 45.

he broke several key rules and the worst was the effective stack screw up. oh yeh and they guy was a total fish/maniac.
