When to give your partner

[SMEngmann]

I agree that basically only when you're 100% sure you're right AND your partner seems unsure with his call should you ask for help. If your partner is emphatic with his call, he has good reason for making it and stay away. If he seems hesitant or unsure and you ARE sure, step in and give him the info. Shouldn't make any difference whether you're being evaluated.

Same thing with foul calls, if you extend, it better be a trainwreck and you know your partner missed it or was screened out, especially in 3-person. Trust your partner's judgement, he/she usually has reason for making/passing on certain calls.
