JLLM will immediately get lost, so I recommend a decent assistant type model for this. GPT-chat works quite well for me. After about move 20 the illegal moves might start, but if you point it out the bot should correct itself (eventually). Reasoning models might be better, haven't tried.

Unfortunately, you may need to correct the material change counter at times as well. You can either ask her to recalculate or directly adjust her response.
