David, you can&apos;t be so wrong - W23 seems even more timid. Such a strategy makes sense if you have to expect two stones for every single stone you play (Such as B1 W5 R6), but that seems to be pretty rare in your game. I have one question: What prevents you guys from ganging up against one of you first, and the tackle the remaining rival? I want to see intrigue and treachery! &gt;:-]]</comment><comment>Difficult to say. How I see it:
 * It seems inappropriate to me to gang up against David, since he is the weakest player. But this may change when he takes a clear lead.
 * It seems inappropriate to me to gang up against Floris, since he has the worst position on the board (at least in my opinion). I&apos;m quite happy with the way things go at the moment.
 * I don&apos;t know the reason for not ganging up against me. There may be an underlying system preventing imbalance. When there is one player ahead, the it is very likely the other two will cooperate to prevent him from winning. But when there are two or more leaders (like in this game until now), they probably prefer to strengthen themselves and trying to take the lead, instead to ganging up against one of the players (more effective).
 * Maybe nobody wants to be the first to propose such a thing (doing that may work against you).</comment></turn>

1. It loses you points.
2. The B9 group can easily escape anyways when you simply cut at &apos;e&apos;. If red playes at &apos;f&apos; however, it will die.
3. Araldo was the one to launch the attack on you that caused ur B9 group to be endangered in the first place.
4. I helped you to prevent red from connecting by playing at H8
5. If Araldo lives I have no choice but to attack you. (Marked stone.)</comment><comment>I also did not think of that. Funny, that only the &quot;weakest&quot; player noticed the solution.</comment></turn>
		<turn><move location="C13"/><mark type="label" location="G13" text="a"/><comment>I guess Floris is right, there seems to be no good reason not to play a for David, and let me die. When this happens, I have clearly no chance to win the game, so in this case, my target will be to become second. This can be accomplished by helping one of you to attack the other. To put it more simple: I can decide the winner. If David plays a, it will be Floris.</comment></turn>

When I first thought of this position, I thought that White would capture immediately and force Red to settle the position, allowing me to rescue my marked group. Now I think that White probably won&apos;t and Red doesn&apos;t have to respond until he does. That leaves a lot of aji in the position.
		
Saving Red make the score more even between White and Red. The goal is to win the game, of course, and so I want to keep my opponents&apos; scores about equal. Concentrating too much on one color allows the other to gain ground. If Red dies, White has three corners and a side, and will probably beat both Black and Red.</comment><comment>Thank you very much, David.</comment></turn>

Thanks anyway.</comment></turn>

		<turn><move location="G7"/><comment>I just estimed the score: David and Floris almost equal, I maybe 15 points behind. So now I have difficulties deciding what to do. Please provide me with some arguments / counterarguments for the following options:

 * Attack only Floris, hoping to get the second place
 * Attack only David, hoping to get the second place
 * Just defend / attack both of you equally, which will make me third

Obviously the first two options are better for me, so it will probably be one of these.</comment><comment>It&apos;s desirable to finish second rather than third. Imagine that this is a tournament game, and the difference between second and third is the difference between advancing or not.

You&apos;ll probably have more luck attacking Black than White. Practically, though, I think you&apos;ll have trouble just surviving. Red is right in the middle of where Black and White want to expand. I especially want to kill you, because many of your stones would become my territory.</comment><comment>Hmm, well Araldo, looking at your stones, I do not think any of them will live, because they do not have a base anywhere, so I am guessing you will be third whatever the case. I don&apos;t think you have many options. The easiest for you is resigning (auto third, David and I would contine). Your next two choices are helping either me or David. I would probably be an easier target because of my B2 group that might be killable with the effort of two (David first, I second, you third). David really doesn&apos;t have much to attack, and reducing is not an option since your stones would die (no possible connection to any base). Another option is attempting to get help from either David or myself to make a living group, although this will be very hard, and the person helping will have to give up points so there&apos;s a chance for him to become second.</comment><comment>You are right, it is likely they will all die. Still, resigning for one person is not an option (not allowed by the rules). What I will do first is a few hopeless attempts to make two eyes anyway. After it is impossible to live, I will pass or make a few random or annoying moves, and see what happens.</comment><comment>You have one eye at G8. I think the rules should allow one person to resign at a time.</comment><comment>I intentionally left it out of the rules. This is because I believe is will severly spoil the rest of the game when one player quits before the end of the game.</comment></turn>
		<turn><move location="H7"/><mark type="x" location="K6"/><mark type="x" location="K7"/><comment>B68 made this move sente. (Red, but not White, has to respond or risk being cut. I guess you can call that sente.) Next, I plan to attack at the marked points.</comment></turn>
		<turn><move location="L7"/></turn>
		<turn><move location="H8"/></turn>
		<turn><move location="L6"/><comment>I think this gives Red a chance of living, but he&apos;ll have to give up the lower right corner, which I hope to keep White from getting and keep for myself.</comment><mark type="label" location="M7" text="a"/><mark type="label" location="K6" text="b"/><comment>(A little later.) As I look at the board more closely, I think that this was not such a good move. White a, Red b solidifies White&apos;s hold on the right side, possibly allows Red to connect, and cuts me off from the right.</comment></turn>

I wasn&apos;t that attached to those stones anyway. But aren&apos;t you being a little reckless? Playing at a would have made a second eye. (Or is there one there already, and I just don&apos;t see it?) I&apos;m not sure there&apos;s an eye on the left after you and White capture the four black stones between you.</comment></turn>

My count shows White comfortably ahead right now.</comment><comment>I don&apos;t understand three way thinking but I wonder why black did not go for a kill. Can red help white to survive? Is it in red&apos;s interest to help white?</comment><comment>It&apos;s because I didn&apos;t know I could kill. In fact, I was surprised that White responded. Of course, since your comment I examined the position more closely. Is this what you had in mind?</comment></turn>

		<turn><move location="L9"/><comment>Well, it seems Araldo would rather see David win than myself, and ofcoarse David agrees with this :) Oh well i&apos;ll continue on because second place isn&apos;t that bad... (Even if u guys kill my bottom left i am still second *grins*).</comment></turn>
		<turn><move location="A3"/><comment>I was not thinking like that at all. 1) there is no possibility to attack David. Only you have got groups which can be attacked. Not much choice here 2) I believe I can become second with help from David. And David can become first with my help. If we kill the bottom left and David let me have sufficient points in this corner (the complete A column should be enough), than this will be possible. I believe you&apos;ve made a mistake by not playing W98 in the bottom left corner.</comment></turn>
		<turn><move location="B3"/><comment>As much as I dislike rewarding the sneaky move of R99, this is good for me. Now White might be able to connect on the right, but that&apos;s worth fewer points than this corner.</comment></turn>
		<turn><move location="B4"/><comment>Count again Araldo ^_^ It is still very close considering you only have 6 points on the board</comment></turn>
		<turn><move location="A4"/><comment>I agree it is very close. I count 10 (6 for me, 16 for you) points more territory for you, but I also count 11 dead+captured stones more for you (3 for me, 14 white). So if I can get a few more dame points than you at the end of the game, I should become second. However, David may decide whether or not I will get those points, so I&apos;m not sure this will happen.</comment></turn>
		<turn><move location="M4"/><mark type="label" location="A5" text="a"/><comment>I don&apos;t think I can gain more in the corner. Red is able to kill White there, but in doing so he allows me to take the whole corner with a, so he shouldn&apos;t do it. If I play a now, White gets back almost what he had before.
