Something I have never seen before

[wdcbooks]

Bless this forum, for this has gone unposted for too long.
From earlier this year. I have had a couple of royals, but never completed the seven card straight flush. If I wasn't a math flunkie I could figure out the odds of this.

Party Poker No-Limit Hold'em Tourney, Big Blind is t50 (7 handed) converter

CO (t745)
Button (t415)
SB (t825)
BB (t1080)
UTGA (t1420)
MP1 (t2220)
MP2 (t1295)

Preflop:
UTGA calls t50, MP1 calls t50, <font color="#666666">2 folds</font>, Button calls t50, <font color="#666666">1 fold</font>, BB checks.

Flop: (t225) T[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">BB bets t50</font>, UTGA calls t50, MP1 folds, Button folds.

Turn: (t325) 6[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets t375</font>, <font color="#CC3333">UTGA raises to t1320 (All-In)</font>, BB calls t605 (All-In).

River: (t2625) 7[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players, 2 all-in)</font>

Final Pot: t2625

Results in white below: <font color="#FFFFFF">
BB has 4d Kh (flush, king high).
UTGA has 9h Jh (straight flush, queen high).
Outcome: UTGA wins t2625. </font>

Converter messed up a bit, but I am obviously whatever UTGA is. Looking back I have no idea why I pushed this hand on the turn, but I suppose it worked.
