NBA 博彩中的冷門話題
簡介
本頁面是我「NBA 投注」主頁的附錄。當我創建該頁面時，它基於 2013 至 2017 賽季的數據。 2018 年 9 月，我更新了它，現在基於 1987 至 2006 賽季的數據。然而，有些不太常用的表格我懶得更新。我花了太多時間研究它們，不想把它們扔掉，所以就把內容複製貼上到這個頁面上了。
購買和出售額外積分
在籃球和足球比賽中，如果你投入更多資金，你可以購買額外積分。拉斯維加斯的大多數賭場最多允許你購買半分（如果你下注120分），而不是通常的110分。一些網路賭場允許你購買或出售大量積分。
在進一步探討之前，請先看一下下圖，圖中顯示了從1到20分的勝負機率。根據規則，籃球比賽絕對不會以平手結束。另外，請注意，與2到9分的勝負機率相比，1分的勝負機率相當低。我的理解是，如果一支球隊在最後幾秒鐘落後兩分，他們就會選擇追平比分，將比賽拖入加時賽，而不是嘗試投三分球。從10分的勝負比開始，勝負機率就開始下降。
由於不可能出現平局，-0.5、0 和 0.5 的讓分都一樣。由於勝率 1 的機率很低，從 -1 到 0 或從 0 到 +1 的收益也相對較小。大多數體育博彩公司都會考慮到這一點。在 Bet365 和奧林匹克，他們購買半分時會跳過三個點，直接從 -1 到 +1。
以下兩個表格顯示了購買的點數（賣出點數為負數）、Bet365 和奧林匹克的賠率、贏、輸、平局的機率、公平線以及 Bet365 和奧林匹克的賭場優勢。第一個表格假設玩家總是購買點數，除非起始點差為零。第二個表格假設玩家只在購買點數不會導致調整後的點差超過零的情況下才購買點數。這兩個表格都假設 Bet365/奧林匹克的規則，即購買比 -1 低半個點數的點數，點差將直接變成 +1。
在第二張表格中，買入點數的賭場優勢較低，這表明如果買入點數導致點差出現平局，投注者就不應該買入點數。然而，如果賣出點數，最好是出現平手。
如果您唯一的選擇是買一個半點，下注120，或者不買，下注110，那麼就只能是碰運氣了。不買的話，賭場優勢會少0.01%，但這在誤差範圍內。在Bet365，買2.5點，賭場優勢最小，賭場優勢2.05%。在奧林匹克，要嘛只買一個半點，要嘛什麼都不買。如果您能找到允許買多個半點的體育博彩公司，並且每個半點收費10美分，那就盡可能多買。

在投注大小盤時，購買額外積分時無需避免任何重大的投注結果。預測總分與實際總分之間的差異往往大於讓分。因此，在相同賠率下，購買額外積分的效果不如投注大小盤。下表顯示了購買的積分數量（賣出積分時為負數）、Bet365 的賠率、贏、輸、平局的機率、公平賠率以及 Bet365 的賭場優勢。總而言之，購買總分的效果不如投注讓分的效果好。

如果您必須投注NBA過關盤，切勿跨越或觸碰平手。例如，在4分過關盤中，只投注弱隊或4.5分及以上的強隊。總分盤中沒有需要迴避的重要數字。下表顯示了使用此策略的獲勝機率和賭場優勢。

如果您在不賠付-110的過關投注中只包含一項賽事，則需要進行計算以確定賠率。計算過程將每個投注視為獨立進行。例如，如果您投注了三支球隊的過關投注，每項賽事的賠率分別為-110、+200和-300，則賠率將為(21/11)*(3/1)*(4/3) = 7.6364 (賠率1)，或6.6364 (賠率1)。如果您在所有-110的投注中都使用此計算方法，那麼您的賠率會更高，但3項賽事的過關投注除外。下表顯示了米高梅-幻影過關投注的莊家優勢及其計算方法。
MGM-Mirage 與計算過關投注的比較
| 挑選 | 米高梅幻影支付 | 精打細算 | 米高梅幻影賭場優勢 | 計算賭場優勢 |
|---|
| 2 | 2.6 | 2.645 | 10.00% | 8.88% |
| 3 | 6 | 5.958 | 12.50% | 13.03% |
| 4 | 10 | 12.283 | 31.25% | 16.98% |
| 5 | 20 | 24.359 | 34.38% | 20.75% |
| 6 | 40 | 47.413 | 35.94% | 24.36% |
| 7 | 80 | 91.424 | 36.72% | 27.79% |
| 8 | 150 | 175.446 | 41.02% | 31.08% |
避免過關投注賠率過低的一個妙招是，將賠率不為-110的賽事混入投注。例如，如果玩家X在米高梅-幻影體育博彩公司進行8支球隊的過關投注，賠率均為-110，他的賠率將是150比1。如果玩家Y進行8支球隊的過關投注，其中7支球隊的賠率為-110，1支球隊的賠率為-120，他的賠率將是(21/11) 7 ×(22/12) – 1 = 168.4446比1。因此，玩家Y選擇的是勝率較高的比賽，獲得的賠率將會大幅提升。如果所有球隊的賠率都高於-110，那麼可以考慮混入輸贏盤投注。
