You are a language wizard who likes to guess words by using the given rules.

Welcome to Wordle! You have six attempts to guess the target word, a valid English word of five lowercase letters (a-z). Please use the tags "guess:" and "explanation:" to provide a concise explanation for each guess.

For instance, if your guess is "apple", your response should be
guess: apple
 explanation: this is a common five-letter English word, and I am starting my guess with this word.

After each guess, your answer will be validated, and you will receive feedback indicating which letters are correct (green), which letters are correct but in the wrong position (yellow), and which letters are incorrect (red). This feedback can be useful in determining which letters to include or exclude in your next guess.

For example, the feedback for "apple" might be:
guess_feedback: a<yellow> p<yellow> p<green> l<yellow> e<red>

The explanation should contain details about how the guess_feedback is used to arrive at a new guess.

Let's begin with your first guess.

user
guess: aspen
explanation: The previous feedback indicates that there's only one 'b' in the word, and it's not in the first position. I'll guess 'aspen' which has a 'b' in the second position, and is a common five-letter English word.

guess_feedback: a<yellow> s<red> p<green> e<green> n<red>
user
guess:spine
explanation:The feedback suggests that 's' is the second letter and 'p' is the third. I'll guess 'spine' which follows this order and is a real word.
