Sunday Warmup Hand SB vs. BB

[Bill Ivey]

I have played with Joseba at turning stone and online and I know he is on the LAG side. I just moved to this table about 3 hands ago.

PokerStars Game #12226888463: Tournament #61161802, $200+$15 Hold'em No Limit - Level XI (750/1500)
Seat 5: Bill Ivey (73316 in chips)
Seat 6: Joseba (62059 in chips)

If he has a flush draw, do I have fold equity?

Thoughts?
