Narrative:
The copilot was cleared for a visual approach to den runway 35R. I noticed him lining up wrong and asked twice if he saw the runway to see if he was correcting. I did not see the B737 airplane at first, on runway 35L and this was letting the copilot correct his mistake when we got a TCASII and I saw the conflict. We climbed and turned steeper to get back in the correct position.
