Isibonelo: Ukubheja esigabeni
“Ishumi nesikhombisa nomakhelwane”, amathokheni amahlanu ngesikhathi, ihora lonke. Ukuthi iseshini yokubheja isigaba sesondo izwakala kanjani nokuthi ibiza malini.
Iseshini elingisiwe yokujikeleza okungu-50 yamathokheni amahlanu ka-$2 ku-2-25-17-34-6, umkhothamo wamagodi amahlanu ozungeze u-17. Ukushaya okuyisikhombisa ekujikelezeni okungu-50, isamba ngu-+$4 ngemuva kokuba silahlekelwe ngu-$120. Ama-straight up amahlanu anendaba, futhi indaba ayishintshi lutho.

Kungani isigaba
Ngoba kungumkhothamo wangempela wesondo, okubalulekile uma futhi kuphela uma isondo lichemele kulowo mkhothamo, futhi asinabo ubufakazi balokho. Ngaphandle kokuchema ukubheja isigaba kungama-straight upukubhejaI-straight upInombolo eyodwa, kukhokha u-35:1.Funda konke → amahlanu angahlobene: inzuzo yekhasino efanayo, inkokheloimaliInkokheloLokho ukubheja okuwinile okubuyisayo, okushiwo ngokuthi “X ku-1” ngaphezu kwenani elibhejiwe elibuyiswayo.Funda konke → efanayo, amathuba afanayo nawezinombolo 2, 25, 17, 34 no-6 ezikhethwe ngoba kwakuyizinsuku zokuzalwa zomuntu othile. I-racetrack yenza kube lula ukubheja ngokushesha futhi inika ubusuku indaba. Izibalo azizifundi izindaba.
Lokho umdlali okhangela ukuchema ayengakwenza ngokuhlukile
Ayeqala aqophe izinkulungwane zokujikeleza kuleli sondo ngqo, athole isigaba esishaya ngaphezu kuka-5/37 kumasampula amabili azimele, bese esibheja ngenani elibhejwayo elilinganiselwe enzuzweni elinganisiwe. Ukushaya kwethu okuyisikhombisa ekujikelezeni okungamashumi amahlanu akubona ubufakazi balutho; ikhasi lobukhulu besampula eLabhorethri lithi singadinga ukujikeleza okuphindwe kayikhulu ukuze sisho ukuthi lo mkhothamo ushisa yini. Sasibheja ngoba u-17 uyinombolo enhle, okuyisizathu esifanayo sawo wonke umuntu.
Imibuzo
Kuyafana ngaphandle uma isondo lichemele kulowo mkhothamo, futhi lokho kudinga izinkulungwane zokujikeleza ukuze kwaziwe.
Itafula elinenani elincane lokubheja elingu-$10 nokubheja okumenyezelwayoitafulaI-call betUkubheja okumenyezelwa ku-croupier kunokuba kubekwe ngesandla, ngokuvamile ukubheja esigabeni sesondo okufana ne-voisins noma i-tiers. Kubuye kuthiwe “ukubheja okumenyezelwayo”.Funda konke → kwamathokheni amahlanu. Inani elincane kakhulu lokubheja kwangaphakathi lisebenza esambeni sonke.
Ukubheja “ngo-3” (omakhelwane abathathu nhlangothi zombili) kubeka amathokheni ayisikhombisa amboza amagodi ayisikhombisa ku-18.9%. Inzuzo yekhasino efanayo, uhambo olubushelelezi.
Okokuhlekisa
Ama-straight up amahlanu anendaba. Isondo alifundi.
