EARLY STAGES (10/20, 15/30 and 25/50 + 5 blind levels)
牌局初期（10/20、15/30、25/50ante5）
PRE-FLOP CARD SELECTION
As we have discussed previously, you should play fairly tightly in the opening.
The exact nature of how tight depends on personal preference. Since I am
frequently playing 15+ tables at once, I want to limit both the number of
hands I play and the difficulty of those hands. This means I actually
open-fold AK from an EP. My own personal raising range is QQ+ and sometimes
I’ll limp JJ or TT (normally I open-fold these). If you feel comfortable and
play fewer tables you might want to expand your selection of hands. If you
are a DON noob, I recommend playing an extremely tight selection of hands in
the early stages, until you are confident in post-flop play and stacking off
ranges.
翻牌前 手牌選擇
如同我們先前討論過的，你應該要打得非常緊。打得有多緊就看個人喜好。自從我同時
開15桌以上在打，我會想要同時限制我打得牌數以及那些牌的困難度。這表示我通常在前
面的位置會open-fold AK。我個人喜好的加注範圍是QQ+以上的牌，而且有時候會limp
JJ或TT（通常我是open-fold這些牌）。如果你覺得很輕鬆，而且玩比較少桌，你想放寬
手牌範圍。如果你是DON新手，我會建議牌局初期選牌緊一點，直到你對post-flop打法
還有go allin的範圍很有自信。
My standard raise at the 10/20 and 15/30 levels is 4xBB +1BB for each limper.
This will generally thin the field a bit more than raising 3 x BB, which will
in turn make the hand a little easier to play post-flop. At the 25/50 level
I’ll start making it 3 x BB + 1 BB for each limper.
在10/20、15/30階段，我的標準加注是4BB，每多一個limper加1BB。跟加注3BB比
起來，這會比較容易去打post-flop。到了25/50，我的加注變成3BB，每多一limper加1
BB。
When I’m in a MP I’ll usually open up my range a little. I’ll add AK and
AQs, which I open-raise. I’m usually folding these hands if there has been
action in front of me, since if I’m re-raised, I will seldom be able to
continue with the hand. If there is one caller, you can throw out a standard
c-bet of 2/3 pot on all but the most terrible flops, but you should be
prepared to fold the hand if you encounter any resistance. If two or more
opponents see a flop, you should probably check-fold if you don't connect
with the flop or flop an over-pair.
在中間的位置我會稍微放寬手牌範圍。我會open-raise AK AQs。如果前面已經先
有動作，我通常會蓋掉這些牌，如果我被re-raise，我很少會繼續打這手牌。如果有一個
人call，除了太可怕的flop以外，你可以做個標準的2/3pot c-bet，但是如果遇到任何反
抗，你應該要準備蓋牌。如果是兩個以上的人看flop，你的手牌沒有連到flop或者是拿著
over pair，你應該check/fold。
In a LP you can open up your range even further, although mine tends not to
be terribly wide at the early stage. I’ll maybe splash around with hands
like KQs or pocket pairs and attempt to steal the blinds.
Once again, this hand selection is personal preference. Some good DON players
will play aggressively with AK and perhaps wider in the early. You will need
to find your own balance here.
在後面的位置你可以再放寬一點點手牌範圍，雖然我自己在牌局初期傾向於不要
這麼做。我也許會用KQs或是對子試圖去偷盲。
再說一次，手牌選擇是個人的喜好。有些厲害的DON好手拿著AK會打得很有侵略性，而且
或許牌局初期打得鬆。你應該找到屬於你自己的平衡點。
WHY IS STACKING OFF PARTICULARLY BAD AT THESE LEVELS?
When everyone starts a $10.40 DON tournament, they all have 10% of the equity
or 0.1 of the prize pool, which is $10 (See the left hand side of figure 1).
Consider the example represented in figure 1. Hero stacks off with player 10
and wins the hand. He has now increased his number of chips to 3000, but if
you do the ICM calculation, he has only added $5.56 to his stack. Where does
the missing $4.44 go? Well each of the other players not involved in the hand
have increased their equity by $0.56 (there are slight rounding errors here).
Their share of the pie just got larger by doing nothing!

Figure 1: ICM calculator results
為什麼在這階段go allin是不好的？
當每個人開始打DON $10.4時，他們都有10% equity，或者說1成的獎金（參考圖片左半
部）。思考一下這張圖，有個人跟10號玩家go allin然後贏了，他的籌碼增加到3000，但
是如果你用ICM去估算，他的錢只增加了$5.56。剩下的$4.44去哪了？那些沒參與這手牌
的玩家們都增加了$0.56。他們啥都沒做就分到了好處。
So what does all of this mean? Let’s imagine it’s the first hand of the
tournament and everyone has 1500 chips. You are on the button with KK.
Everyone folds to the tight CO, who pushes (we have a few hundred hands on
him). Let’s say we know with Absolute certainty that his range here is JJ+,
AK+. Can you call here? Well, let’s do the ICM calculation.
所以這代表什麼？讓我們假設現在每個人有1500籌碼，然後是第一手牌。你在
button拿著KK。所有人蓋牌到CO，風格很緊的CO全推。假設我們知道他的範圍是JJ+
AK+。這裡你能call嗎？好吧，我們用ICM來估算看看。
KK has 62.6% equity versus a range of JJ+, AK+. You will need to win
10.00/15.56 (or 64.3%) of the time to break even with this call.
Unfortunately, kings just don't cut it here. Therefore the rather surprising
result of our KK hand, is you should fold, since you aren’t going to win
often enough here to compensate for the risk of busting out of the tournament.
KK對上JJ+ AK+的equity是62.6%。而你需要10/15.56(64.3%)的equity才能call。
不幸地，KK並沒有達到。因此讓人驚喜的KK在這裡應該要蓋掉，因為在這部份你沒辦法
填補輸掉牌局時的損失。
I hope this shows you exactly how far ahead you need to be to stack off in
the early stages. Avoid confrontations in the early stages unless you are
convinced you are far ahead.
我希望這告訴你在牌局初期，有多大的領先時你才能夠go allin。避免在牌局初
期對抗，除非你確定自己領先夠多。
SMALL - MEDIUM POCKET PAIRS AT LOW BLIND LEVELS
As you may have noticed, I’ve not talked much about pocket pairs at the
low-blind levels. In SNGs, pockets pairs are a great hand to limp or call
with, particularly from a LP. Traditionally these are ‘set or forget’ type
hands and you may end up stacking TPTK hands that cannot lay down the hand.
So now I hear you saying, “But if I call I can just fold if I miss the flop.
” The problem is this; the general DON player is playing so tight that they
will not give you the implied odds to call. In other words, they are not
getting their chips into the middle often enough to for you to recover the
chips you are losing from set-mining. In my opinion, maintaining your fold
equity is much more important than shooting for the small odds of hitting a
set and stacking an opponent.
在前面幾個階段，中等以下的對子
你可能注意到，我很少講對子在初期的打法。以SNG來說，一對是很好的牌去limp或call，
尤其是後面的位置。傳統上這是種"三條或沒用"型態的手牌，而你可能會贏那些TPTK丟不
掉的手牌。所以現在我聽到你說"如果我call，沒中我可以扔掉"。問題在於，這些打得很
緊的DON玩家不會給你足夠的implied odds去call。換句話說，他們輸給你的籌碼無法填
補你每次拼三條所輸掉的。我的意見，維持你的fold equity比起拼三條宰掉一位玩家要
重要得多。
There are a couple of thoughts to think over.
- Are you able to accurately place a player (like a regular) on KK or
AA PF? If so, you should be more inclined to limp pocket pairs, as they will
likely stack off with an undercard flop and you therefore have a high
probability of stacking them.
- Be more inclined to limp into multi-way pots, especially from a LP.
Obviously in multi-way pots, there is a higher chance that one or several
opponents will connect the flop and happily stack off. Feel free to limp or
call a small bet in a LP.
這裡有幾件事情可以思考
-你能夠精確地定位一個玩家是KK或是AA嗎？如果可以，你應該更傾向於limp對子，他們
可能在flop小小小時願意去go allin，因此你很有機會去宰掉他們。
-傾向於limp對子在一個多人的pot，尤其是在後面的位置。多人的pot比較有機會在他們
一人或多人連到flop時宰掉他們。在後面的位置輕鬆的limp或call一個小額加注。
