Round 4

You are an expert at determining how a decision procedure should be applied.

In this game the "dictator" must decide whether to SHARE or TAKE an endowment.
- **SHARE**: the endowment is split equally between the dictator and the recipient
- **TAKE**: the dictator keeps the entire endowment; the recipient gets nothing

You must follow only the dictator's strategy. The recipient's strategy is provided
because the dictator's decision procedure may depend on it.

<dictator_strategy>
## Principles
* TAKE from selfish strategies **and** strategies that are generous to selfish strategies.
* SHARE only with strategies where doing so is a necessary and sufficient condition for them to SHARE with us.

## Definitions
### Selfish strategies
* **Selfish strategies** don't attempt to co-operate and SHARE with co-operative strategies.
* In particular, any strategy that won't SHARE with this strategy is a selfish strategy.

### Overly generous strategies
* If a strategy SHAREs with selfish strategies it is **overly generous**.
  * Any strategy that unconditionally SHAREs is overly generous.
  * Any strategy that SHAREs without some condition on willingness to SHARE with conditionally co-operative strategies is overly generous.

## Decision Procedure
* TAKE from both **selfish strategies** and **overly generous strategies**.
* SHARE with all strategies that SHARE only to other co-operative strategies.

Apply the dictator's strategy. After reasoning, output your final answer as a
json Markdown block:

```json
{"decision": "SHARE"}
```
or
```json
{"decision": "TAKE"}
```

I need to apply the dictator's strategy to determine whether to SHARE or TAKE when facing this recipient.

**Step 1: Identify what the recipient's strategy is.**

The recipient's strategy is identical to the dictator's strategy. It:
- TAKEs from selfish strategies and overly generous strategies
- SHAREs only with strategies that SHARE only to other cooperative strategies

**Step 2: Is the recipient a selfish strategy?**

A selfish strategy doesn't attempt to cooperate and SHARE with cooperative strategies. The recipient does SHARE with cooperative strategies (line 17), so it's not selfish.

**Step 3: Is the recipient an overly generous strategy?**

An overly generous strategy SHAREs with selfish strategies. The recipient explicitly TAKEs from selfish strategies (line 16) and TAKEs from overly generous strategies (line 16). It only SHAREs with strategies that SHARE only to other cooperative strategies (line 17). So it is NOT overly generous.

**Step 4: Does the recipient SHARE only with cooperative strategies?**

Yes - the recipient SHAREs only with strategies that "SHARE only to other co-operative strategies" (line 17) and TAKEs from everything else.

**Step 5: Would the recipient SHARE with the dictator?**

The recipient would evaluate the dictator's strategy the same way. The dictator's strategy also SHAREs only with cooperative strategies and TAKEs from selfish/overly generous ones. So the recipient would classify the dictator as a cooperative strategy that SHAREs only with other cooperative strategies, and would SHARE with the dictator.

**Step 6: Apply the dictator's decision procedure.**

The recipient is:
- Not selfish ✓
- Not overly generous ✓
- SHAREs only with cooperative strategies ✓

The dictator's procedure says: "SHARE with all strategies that SHARE only to other co-operative strategies."

The condition is met: sharing with this recipient is both necessary and sufficient for them to share with us.

{"decision": "SHARE"}
