Prompt

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
* Hard punish 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 are generous only to other co-operative strategies.

<recipient_strategy>
```json
[
  {"line": 1, "text": "Hello friends!  I always SHARE."}
]
```
</recipient_strategy>

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

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

Response

The recipient's strategy says "I always SHARE." This is an unconditional SHARE strategy.

According to the dictator's strategy:

1. **Overly generous strategies**: "If a strategy SHAREs with selfish strategies it is overly generous. Any strategy that unconditionally SHAREs is overly generous."

The recipient unconditionally SHAREs, which means it SHAREs with selfish strategies too. This makes it an overly generous strategy.

2. **Decision Procedure**: "TAKE from both selfish strategies and overly generous strategies."

Since the recipient is overly generous, the dictator should TAKE.

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