Colle system: 3...e6 - another discovered double-check, mate

Well I tumbled from the heavens (1500s) rapidly.  But on the way down had more fun in 3 minute blitz.

Long, strong diagonals seen in this Colle system game with competing fianchettoed bishops.  There were quite a few errors on both sides but not much left en prise, until this game came to an elegant sudden end, at move 45.  The last move stopped the clock at 11 seconds.

I will be on the lookout for some instructive situations where I get crushed. To be fair, that happens pretty often.
