interesting Poker hand

1 unit small blind, 2 units big blind, I was with short stack of ~17 units left. my hand Jack (Spade), 10 (Club)

players make initial blinds go up +5 units, I was initially in the big blind position, so I go All-In, and only Players B & C called.
Then player C challenged B into a side pot of All-In.

Flop: 7 (Spade), 8 (club), 9 (spade)... ==> I already have a straight!
player B: Ace and a low card
player C: 9 (heart), another card in Spade.

next comes Q (spade).. -> I lost to player C since that hand is a Flush... Oh, well, I tried! Good Game
