So I've played euchre for 25 years+ but only just now started to really try to up my game. It's funny, reading through things on here opened my eyes to "patterns" I was seeing before and never really exploited, I just knew what was most likely to be called based on my hand and the up card. Already I know my game is better.
I've been implementing the BPS system (or trying) and most types of calls I've pretty much figured out how to play, I'm still working on it. However, these types of hands i am at a loss on how to play and seem to go 50/50 on, meaning I shouldn't be playing them as I am losing points over the long haul. I wanted to see what the best way to play these hands are:
Players are equal and lets say its 0-0 as I don't make these calls late (unless opponent has 9)
Up card is

I'm dealer and my hand is





According to BPS I need 2.0 to call. So if I am doing this correctly:
R1S4 .5 (.5)
1 Void .25 (.75)
Trump .75 (1.5)
Green Ace .75 (2.25)
I've reached my 2.0 minimum.
I order up and discard the






Here are the potential scenarios I'm struggling with:
#1 I get lucky and Spades are led and my Ace holds up, what do I do next? I have been throwing my low club card as my partner passed on hearts so I'm assuming we won't win if I throw trump and I might rob them of the help I need, is this correct?
#2 Diamonds are led and I trump in. Do I come back with the Ace or through low club or burn my last trump on the unlikely scenario that my partner can take it. I've been coming back with my Ace, is this correct?
#3 My partner trumps in the first trick, leads back trump and I pray we can hang on
#4 Clubs are led, I throw low. Then if diamonds come back and I trump in, do I throw my trump to clear it out and hope my Ace plus

Thanks in advance for the help!
