是否立即加買?

在 2+2 經常看到有人說在加買 (Rebuy) 比賽中,一開始立即加買,但到底是否正確?下面我來一個分析。

假設在一個加買比賽,開始時是1500籌碼,加買是1500籌碼,加碼 (Addon) 是2000籌碼,你在多桌賽的平均回報率 (ROI) 是30%,先看看一個比賽的加買和加碼情況:

按上圖的加買情況,每1500籌碼的價值為$7.56,每2000籌碼的價值為$10.08,如果你是沒有賺錢的玩家,再買入就變成了虧本,但一個平均回報率30%的玩家加買的價值卻是:

$7.56 * 110% (費用應計算在內) * 130% = $10.81

每個加買可獲得 35% 的回報率,所以如果資金許可的情況下,可以考慮加買。

但如果加碼變成3000籌碼的話,每1500籌碼的價值為$6.82,每3000籌碼的價值為$13.64,加買的價值為:

$6.82 * 110% *130% = $9.75

仍然有21%的回報率,因此加買仍然是可以考慮的,但如果你很在意回報率的減少,不加買也無妨。

我們再看另一個加買衛星賽的情況:

在上面的比賽中,開始和加買是1000籌碼,加碼是1500籌碼,每1000籌碼的價值為$9.13,每1500籌碼的價值為$13.69,平均回報率為20%的話,加買的價值是:

$9.13 * 10% * 20% = $12.05

因為加買沒有費用,仍然可以取得20%的回報率,但在加買衛星賽需要考慮名次的影響,如果是像$39+R百萬衛星賽,名次的影響太大就可以不加買了。

12月5日新葡京星期六90k保証凱旋 5 Dec Grand Lisboa Saturday 90k guaranteed victory

說幾手重要的牌,有些我都不記得了。

中間一個人跟,我在 SB 跟了 97o,翻牌 8 6 5,我加,中間再加,我 all in,他竟然跟 T8。

中間一個人跟,我在按鈕加注 A8s,中間跟,翻牌有 A,我加,對手跟,轉牌出 8,對手把餘下不多的全進,對手是 A9s。

前位全進約 10BB,我看到 QQ 跟了,對手是 AQ,又拿一手。

前面兩個 limper,APPT 澳門第三名的台灣人全進,當時是 300/600 ante 50,我看到 AQs,當時我有三萬多,要求數籌碼,發現要跟 15k 那麼多,無奈只有放棄。

中間很多都不記得了,到了最後四名我基本上都是 suck out 對手完成,不過這就是比賽。

CO 加注 KTs,按鈕跟,BB 美女 all in 不多的籌碼,我全推走按鈕,美女是 KJs,但我拿到順,現場一片嘩然,剩三個人。

按鈕全進,我在 SB 跟了 AQs,對手 A9s ,我成為 CL。

我在按鈕全進 J5o,SB 跟了 5個 BB 不到,他是 TT,輸了。

我在按鈕全進 J6s,SB 跟了AJo,河牌出 6,進入 HU。

最後一手全推,好像是 T5o 吧,對手跟了 77,但我贏了。

A few important hands, I have forgotten many hands.

Someone limped in MP, I completed at SB with 97o. Flop: 8 6 5. I bet, MP raised, I shoved and MP called with T8!

Someone in MP limped, I raised at button with A8s and MP called. Flop had A, I bet and he called. Turn was 8, MP shoved the remaining chips and I called. MP had A9s.

Someone in EP shoved for about 10BB and I called with QQ. He had AQ and my hand won again.

Two limpers and the Taiwanese who got 3rd in APPT Macau shoved. I found AQs so I requested for chip count and I need to call 15k at 300/600 ante 50. Never mind, next time.

I have forgotten the other hands until the final 4 which I sucked out everyone of them. This is poker tournament.

I raised KTs at CO, button called, the girl at BB shoved for remaining which I at least should call. I pushed the button out of the pot. The girl had KJs, but I got straight. The venue was so noisy like WTF this guy is doing lol. 3 players remained.

Button shoved and I called with AQs. Button had A9s and I became chip leader.

I shoved J5o from button and SB called TT with less than 5BB. I lost.

I shoved J6s from button and SB called AJo. 6 on river so HU.

At the final hand I shoved T5o? and opponent called 77 but I won the hand and the tournament.

[新竟技] 回顧10月16日撲克之星8.8+R 三萬刀保証的勝利

本來打算繼續寫些技巧的文章,但獲得一個比賽大勝,還是想先寫一個回顧,下次再來技巧的討論。10月16日經過9個多小時,我終於打敗其他1,948名對手,獲得7,982刀的獎金,以下是一些這個比賽過程的分享,因比賽較長我只把比較特別的牌貼出來,一般翻牌前全進的就不說了:

第一手
在再買入階段,因為有人亂推,我幾乎沒打什麼牌,拿到 AA 也被 badbeat,過了再買入及 addon 後我只有三千多,但過了這階段我的運氣開始好起來。在 100/200 拿到 AA 及 AK 翻牌前全進都贏了增至一萬多,然後AQ在150/300神差鬼使地超大全進,不知是否因為在前面的11+R鼠標滑了一滑本來加注的牌變成全進輸給 AK 搞傻了,不過這又 badbeat 了對手增至三萬多,請注意不要這樣打啊:

第二手
這手是一個試探式偷雞,當時BB不在,跟這牌又沒什麼意思,但偷雞不成功,其實我很少這樣打,當然如果是T8s的牌我就寧願跟好了:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t200/t400 Blinds + t50 - 9 players

Hero bets t2800, UTG raises to t5600, Hero folds

第三手
河牌成4條,本來對手不會全進的牌變成全進,籌碼又回到較早前的水平,翻牌也可以直接先下注,但想看對手會不會繼續下注:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t300/t600 Blinds + t50 - 9 players

Hero wins t180

第四手
輾轉已到了三十萬籌碼,不過前面的都是翻牌前全進,也不說了,這手牌也可以早一點加注,但考慮如加注後是否跟全進,而且抽的牌也不少,就先看看河牌再說:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t2000/t4000 Blinds + t400 - 7 players

BB: t215009 M = 24.43
UTG: t102972 M = 11.70

River: (t57022) Jc (2 players)
BB bets t30000, Hero raises to t297592 all in, BB folds

第五手
這裡我肯定會跟 MP2,但我沒有想到 SB 會用AJo來全進,當時只想到SBBB一定會非常緊,結果成全了MP1單獨享受:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t3000/t6000 Blinds + t600 - 9 players

SB: t212542 M = 14.76
BB: t106944 M = 7.43
UTG: t549167 M = 38.14
UTG+1: t224252 M = 15.57

MP1 shows Ah Kd (a straight, Ten to Ace)
MP2 shows Tc Ts (three of a kind, Tens)
MP1 wins t60134
MP1 wins t253897

第六手
對手翻牌只跟,轉牌還有接近2個池,公共牌有兩個抽花這時不容對手抽,但翻牌給了對手兩對,還有一定的籌碼但形勢沒有那麼好了,但後來也重新打上去:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t3500/t7000 Blinds + t700 - 8 players

CO: t166942 M = 10.37
BTN: t193101 M = 11.99
SB: t479967 M = 29.81
BB: t271952 M = 16.89
Hero (UTG): t429796 M = 26.70
UTG+1: t461265 M = 28.65
MP1: t282238 M = 17.53
MP2: t93989 M = 5.84

River: (t579176) 8h (2 players - 2 are all in)

Final Pot: t579176
Hero shows Qh As (a pair of Aces)
MP1 shows Jc Ah (two pair, Aces and Jacks)
MP1 wins t579176

最終桌

到了最終桌時我的籌碼有百五萬,比領先者少一點,但大部份人的籌碼也相差不多,OPR也沒有發現任何高手,其中右邊第一位是領先者,有一段時間和我一同領先其他對手不少,最後倒在第三位,右邊第二位是後來和我單打的,在這場比賽同桌了幾百手牌了,這兩人在最終桌早期都經常加注,但後來都好像愈打愈緊,可以說較大的籌碼都在右邊,對我也有位置上的好處,最終桌開始時的注碼是15K/30K。

第七手
第一手較有價值的牌,利用位置的優勢把不小的池偷了下來,這手牌以後右邊似乎在SB跟少了牌,當然這樣打要注意:一是位置,二是對手,另外籌碼數是否需考慮?這時雖然我們是領先者,但並沒有比其他人領先很多,當然如果對手敢全進,恐怕我還得放棄,其他打法如在翻牌繼續下注也是可以的:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t25000/t50000 Blinds + t5000 - 8 players

MP2: t467819 M = 4.07
CO: t629777 M = 5.48
BTN: t916903 M = 7.97
SB: t2087995 M = 18.16
Hero (BB): t2264079 M = 19.69
UTG: t1239760 M = 10.78
UTG+1: t1437545 M = 12.50
MP1: t519122 M = 4.51

Pre Flop: (t115000) Hero is BB with 8d As
6 folds, SB calls t25000, Hero raises to t150000, SB calls t100000
Flop: (t340000) Jd Ks Kd (2 players)
SB checks, Hero checks
Turn: (t340000) 7d (2 players)
SB bets t200000, Hero raises to t500000, SB folds

第八手
這次連加兩次對手不領情了:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t25000/t50000 Blinds + t5000 - 8 players

MP2: t439609 M = 3.82
CO: t399777 M = 3.48
BTN: t1278447 M = 11.12
SB: t1762995 M = 15.33
Hero (BB): t2865745 M = 24.92
UTG: t1239760 M = 10.78
UTG+1: t1317545 M = 11.46
MP1: t259122 M = 2.25

Pre Flop: (t115000) Hero is BB with 6h 3h

Turn: (t280000) 5d (2 players)
SB checks, Hero bets t150000, SB calls t150000
River: (t580000) 2h (2 players)
SB checks, Hero checks

Final Pot: t580000
SB shows Js Qh (a pair of Queens)
Hero mucks 6h 3h
SB wins t580000

第九手
這手不跟我直接全進,如果是的話不知會怎樣,他也亮了QQ出來:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t40000/t80000 Blinds + t8000 - 4 players

BTN: t1298436 M = 8.54
SB: t1732428 M = 11.40
BB: t3576835 M = 23.53
Hero (CO): t2955301 M = 19.44

Pre Flop: (t152000) Hero is CO with Kc Ad

Flop: (t472000) 9s 3d 5s (2 players)
BB checks, Hero bets t255555, BB raises to t800000, Hero folds

Final Pot: t983110
BB shows Qd Qh (a pair of Queens)
BB wins t983110

第十手
KQo在這裡反加全進大了點,小反加不好跟全進同時盲注全進我也不能走,但我覺得這牌還是值得一跟的,可惜沒有把他的全吃過來:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t40000/t80000 Blinds + t8000 - 4 players

SB: t1042436 M = 6.86
BB: t1516428 M = 9.98
CO: t3992390 M = 26.27
Hero (BTN): t3011746 M = 19.81

Pre Flop: (t152000) Hero is BTN with Ks Qd
CO raises to t240000, Hero calls t240000, 2 folds

Flop: (t632000) 8h Qc Kd (2 players)
CO checks, Hero bets t380000, CO folds

第十一手
右邊的輸了一手牌給另一位,奇怪在那一手以後他好像總是被壓制的一方,好像這一手:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t50000/t100000 Blinds + t10000 - 3 players

SB: t3680997 M = 20.45
BB: t2022257 M = 11.23
Hero (BTN): t3859746 M = 21.44

Pre Flop: (t180000) Hero is BTN with 8c Qs
Hero raises to t250000, 1 fold, BB calls t150000

BB checks, Hero bets t300000, BB calls t300000
Turn: (t1180000) Qc (2 players)
BB checks, Hero bets t3299746 all in, BB folds

第十二手
右邊的對手以極少籌碼老死不掉,我用這樣的牌都可以放心偷第二位的,因為他明顯不敢和我硬碰也沒有這能力:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t50000/t100000 Blinds + t10000 - 3 players

BB: t3792125 M = 21.07
BTN: t133544 M = 0.74
Hero (SB): t5637331 M = 31.32

Pre Flop: (t180000) Hero is SB with 4s 5h
1 fold, Hero raises to t200000, 1 fold

第十三手
這是另一手,在其他時間跟會好一點,但因為第三位籌碼實在太少了,他現在沒有很大的牌都不能跟我的全進,如果他跟了而我輸掉,我仍是極大可能進單打,所以這樣的打法能成立:

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t50000/t100000 Blinds + t10000 - 3 players - http://www.thehandconverter.com/hands/328660

第十五手

Poker Stars $8.00+$0.80 No Limit Hold'em Tournament - t50000/t100000 Blinds + t10000 - 2 players

第十七手
最後的一手,前面有一手我用A7o 在BB反加了他(不全進)而他放棄了,這次可能因為前面我打得很鬆,選擇用A4o 4-bet我,可惜時機不對,戰鬥也結束了:

時隔一年 After 1 year

2008年10月18日,我取得了 11+R 第一名並獲 5490 刀,想不到這個記錄等了整整一年才能打破,幾次較大 FT 都贏不到,8.8+R 從10月16日晚 10 時一直混戰到早上 7 時多,我拿了第一並獲 7982 刀。

在 FT 階段我和右邊的一個人一直領先,一直到 3 個人時右邊的籌碼一次籌碼大減以後,莫名其妙經常只有 2-3BB 都不打牌,因為我籌碼領先,帶給我偷另一個人籌碼的良機,最後單打時前面的鬆終於迎來對手把籌碼全給我的時刻,他用 A4 4-bet 我,我卻拿著 AA,戰鬥也就此結束了。

我將會在下一期新竟技雜誌回顧這場比賽。

On 18 Oct 2008, I won $11+R on PS and won the first prize of $5,490. I cannot imagine I need to wait a whole year to break this record as I didn't win several final tables in big MTT. On 16 Oct 2008, I played $8.8+R from 10pm for more than 9 hours. I won that tournament and obtained the first prize of $7,982.

During FT, the player on my right and me kept leading in chips until 3 players left. Then he lost some chips to another players and suddenly played tighter even he had 2-3BB left. Since I have the biggest stack I can steal from another player very easily. Those loose plays finally made me get all the chips during headsup. He used A4o to 4-bet me, but I had AA. The battle is finished.

I will give a review of this tournament in next issue of online magazine 新竟技雜誌.

[cpf123 新竟技文章] 比賽中15BB (或 M = 10)時期的加注打法

我在cpf123論壇上已經指出在這時期各類底牌的優劣,在此我以下列的表來簡單重複一次:

底牌類型 轉牌前跟全進的能力 被跟打轉牌後的能力
小對 22-55 中下 下
中對66-99 中上 中
小同花連牌(如 54s) 下 下
大同花連牌(如 JTs、KTs、AXs) 中下 中
大連牌不同花(如 QJo) 下 中下
大 A (AT – AQ) 中上 中上
大對及AK (TT-AA、AK) 上 上

好了,現在說一下當前面都已經棄牌,你決定是否加注還是放棄(要注意我這裡說的是沒有跟注,在這個時期要打只有加注,因為隱含賠率不高,單跟注只有眼睜睜看著後面一個加注偷去你的籌碼,加注的話只要加注偷的籌碼比被反偷放棄的籌碼多,就已經滿足了),要考慮的因素有:

1. 我加注後是否能跟全進
2. 如果對手跟,我的牌轉牌後好不好打
3. 對手的籌碼數
4. 對手跟注及反加的可能

下面解釋以上的因素怎樣應用:

情況1:
你在槍下,首先看看後面對手的籌碼,假如全部都有大約 M=10或以上,而這張枱的對手不是反加便是不打,那麼除了能跟全進的一些牌,其他的牌作用只能是偷籌碼,這時你用72o 加注或是用 JTs 加注,作用是沒有分別。但是如果有些對手會跟注,而你被反加的機會不是很大, JTs 這些牌變成除了偷籌碼還是有作用的一手牌。至於像 22-55 這些牌,又不能跟全進,轉牌後又不好打,最好還是不打。

不過,如果你不打JTs 也沒有關係,但是若是你知道除了能跟全進的牌那些牌較好,你可偶而選擇打一些邊緣牌,如果桌是比較鬆的,還是不要打JTs,集中打強牌好了。

情況2:
你在槍下,緊跟後面的兩個對手有 M=10 以上的籌碼,後面其他人都是只有 M=5以下,除了緊跟你的兩個對手任何人反加你都能跟,這時你拿 44,如果當成 15bb 的打法這牌是不好打的,但對於這手牌假設緊跟後面的2人因位置問題都不會隨便跟或反加,如果他們反加基本上都可以放棄,這時你加 44 的話是等於除那兩人外是把其他對手打成全進(因為反加可以跟),44 變成能加注的牌,如果對手只跟的話你基本上可以轉牌後100%全進 。但是這時若是 JTs,加注便不好了,因為你沒有道理在槍下全進後面的人,當一個對手反加你全進,JTs 變成不好的一手牌。

情況3:
你在按鈕,前面所有人已放棄,因為只有兩個人偷的成功機會較大,不過對手也可能同時會這麼想,如果你偷的太多,會觀察的對手識破你的意圖後便會大量的反偷,因為雖然對手在盲注,一個反偷全進都不用轉牌,這時你便會很困難,請記著對手這樣打的話位置最佳是 大盲,不是按鈕,所以你加注的話要考慮在這裡加注什麼牌能跟反偷,什麼牌不能,對著實力強的 大盲 (當然還有些實力不強但不管怎樣反偷了再算),不能跟全進的牌不能太多,否則吃虧的反而是你。當然如果對手是弱緊手多一些加注也是可行的,因為對手反加只會是有份量的牌。

下期我會對反偷及對付反偷作一討論。

單桌賽重要的概念: ICM

ICM (Independent Chip Model) 在單桌賽是非常重要的,在多桌賽也有影響,但因為剛剛進錢時只有很少錢,重要性不如單桌賽。

在單桌賽中,第三名可拿到20%的獎金,但第一也只拿到50%的獎金,因此愈到比賽後期,特別是在4人的時候,變得非常重要,這時你拿到翻倍的籌碼,但你的 EV 並沒有翻倍。

看看 Leslie (Player 3) 一場單桌賽,4個人的時候他拿 AA 然後把其中一個對手淘汰的情況:

4人時:











3人時:











可以看到他雖然籌碼翻倍,但 EV 只能從 0.23 增加至 0.37,反而其他兩個沒有出局的 EV 都增加了,因為他們已確定進錢。

ICM 怎麼算?以下是我自己在 Excel 中的計算:









假設所有人的實力一樣,拿第一的機會大約是按籌碼的比例計算,然後再算第二的機會,首先其中一個拿了第一,另外兩人的籌碼數對比得出拿第二的機會,再把它們加起來,其他就是第三的機會了,再把每個名次的機會乘以所得的獎金比例加起來,就得到各人 EV 的數。

如果上面是跟的情況,要算出什麼牌能跟,(實際不是 pf 前跟,不過以下計算是給各位看看要跟多緊):

勝率 x 增加的 EV = (1 - 勝率) x 減少的 EV
w% x (0.3733 - 0.2365) = (1-w%) x (0.2365 - 0.021) (輸了該手牌 EV 降至 0.021,在此不再計算)
w% = 0.2155 / 0.3733 = 57.73%

你要有 57.73% 才能跟,如果對手打 30% 的話,你將只能跟 AJo, ATs, 99+。

所以在4人時你必須要跟得很緊,如果你是推的那位,你現在排第二,後面有人比你多,你也要推得比平常緊,如果你排在第一,並且有一段領先距離,這時你可以比平常鬆很多,盡情欺負小籌碼。
