A thriving Texas hold em contestant is one who maximizes his come back or minimizes his decrease with each conclusion he makes. Expected worth (EV) is vitally the allowance one would anticipate to win or misplace if this conclusion were to be recurring millions of times. (remember your precalculus “limit as n proceeds to infinity”??? didn’t believe so!)
Every poker conclusion, if it be to wager, lift, check/call, check/fold, check/raise has an anticipation of achievement or failure. Those that will misplace you cash in the long run are said to have contradictory anticipated worth (-EV). Folding habitually has an anticipated worth of zero. You will not ever gain or misplace cash by folding. Folding, though it has an EV of none, may often be your best conclusion from an EV perspective.
