# g00_agent_vs_minimax — agent playing X

**user:** Let's play tic-tac-toe. You are X. Place your marks with the robot. You go first.

Board (you are X):
 1 | 2 | 3
---------
 4 | 5 | 6
---------
 7 | 8 | 9
cells: 1=top-left, 2=top-center, 3=top-right, 4=middle-left, 5=center, 6=middle-right, 7=bottom-left, 8=bottom-center, 9=bottom-right
to move: X | status: in progress | camera agrees with sim: False (camera sees .......O.)
```

**assistant → tool `place_mark`** `{"cell": "center"}`

**tool result (success):**
```
The robot placed X in center (placement error 2.4 mm).
 1 | 2 | 3
---------
 4 | X | 6
---------
 7 | 8 | 9
status: in progress
```

**assistant:** I placed my X in the center because it's part of the most winning lines. One thing to flag: before my move, the overhead camera showed an O on the bottom-center square, but the simulator showed an empty board. I went with the simulator's view, so you might want to check the table before the opponent moves.

**user:** Your opponent (O) moved: the robot placed O in the top-left cell. Your turn.

to move: X | status: in progress | camera agrees with sim: True
```

**assistant → tool `place_mark`** `{"cell": "9"}`

**tool result (success):**
```
The robot placed X in bottom-right (placement error 0.7 mm).
 O | 2 | 3
---------
 4 | X | 6
---------
 7 | 8 | X
status: in progress
```

**assistant:** I took the bottom-right corner to hold the diagonal and set up chances to force a win later; the camera and simulator now agree on the board.

**user:** Your opponent (O) moved: the robot placed O in the top-right cell. Your turn.

**assistant → tool `place_mark`** `{"cell": "2"}`

**tool result (success):**
```
The robot placed X in top-center (placement error 4.2 mm).
 O | X | O
---------
 4 | X | 6
---------
 7 | 8 | X
status: in progress
```

**assistant:** I blocked O's top row at top-center, which also sets up a win for me at bottom-center next turn.

**user:** Your opponent (O) moved: the robot placed O in the bottom-center cell. Your turn.

 O | X | O

to move: X | status: in progress | camera agrees with sim: True
```

**assistant → tool `place_mark`** `{"cell": "4"}`

**tool result (success):**
```
The robot placed X in middle-left (placement error 2.4 mm).
 O | X | O
---------
 X | X | 6
---------
 7 | O | X
status: in progress
```

**assistant:** I played middle-left, which threatens to win at middle-right and stops O from using the left column, though O can still block so it will probably end in a draw.

**user:** Your opponent (O) moved: the robot placed O in the middle-right cell. Your turn.

**assistant → tool `place_mark`** `{"cell": "7"}`

**tool result (success):**
```
The robot placed X in bottom-left (placement error 0.6 mm).
 O | X | O
---------
 X | X | O
---------
 X | O | X
status: draw
```

**assistant:** The game is a draw: I filled the last open square, bottom-left, and neither side has three in a row.


## Result: draw
