horrible situation... I don't think I'd have the guts to open the 1 & 8 with my first visit in a league game (I presume this is standard WR one-frame pool). So much that can go wrong here and you're opening the 8 up so if it does go wrong you're toast. Plus even if you hit the 8 perfectly after screwing off the 1 you've got an absolutely nightmarish shot on the 2, tight angle and cueing off the cushion on an English pool table on your second visit... I'd need a new pair of pants after taking that on!
I'd be more likely to nudge the 2 off the cushion & very slightly closer to the pocket and leave myself low on the 1 to thin-tap it as close as possible to the 8 (and in-between the 8 and the 9) and also leave a snooker so the white is behind the 1 & 8. Crucial to get the snooker and tie up the 8 at the same time though, so ensuring being low after you nudge the 2 is key.
This way, even if he's good enough to pot his last ball from anywhere, if you've tied up the 8 (especially if he won't be able to see it from where the 9 is which is presumably his most likely position if he has to kick the 9 in) he's never clearing from there imo. I'd bet against Chris Melling kicking the 9 in and still getting on the black in that situation lol
I can't access cuetable from this PC but hopefully you understand what I'm saying here
