Euchre

I like playing the game but there is a few things that need to be fixed! My partner does NOT triumph the other team when they play a king of a different suit but they dont have that suit so they SHOULD triumph it!! On 3 different games now the opponent has played like a king of diamonds and lets say clubs are triumph and my partner has NO diamonds but DOES have like a 9 or a 10 of clubs but doesnt play it! All 3 times weve had 2 tricks and if my partner woulda triumphed the diamond trick we would have euchred them! There is NO reason to save a 9, especially when you can triumph and catch a trick with it!! Also I have done everything I can but can NOT figure out how to tell my partner to pick it up when they have dealt & I want to make what theyve turned up triumph. The only thing I can seem to do is go alone or pass. Can I not tell my partner to pick it up? If I want that trumps do I HAVE to go alone? Please address these things and it will make the game better!! Thanks!!
