i want ask how would you feel or even if you would fold 5K not suited in preflop and on turn you would get four of kind .
you don't worry about anything like that happening. if it does, oh well. shrug it off and don't be result oriented.
it's about long term profitability and k5 is not winning in the long term. and it's hitting quads so very rare at .001% by the river that playing bad
hands just because you might hit it is a very losing strategy.
this goes for all bad hands. sometimes they'll be winning hands. due to
equity, all hands have a chance to be winning hands, but there is a difference between hands what win in the long run and those that don't.
