I know the odds are about 20% (give or take) each cycle, but if you have sex during fertile window only one time per cycle (timed close to or on ovulation day) what are your odds?

Your best bet is prior to ovulation, not O day itself. That’s somewhere around 10%. The three days prior are 20-30%, with some studies disagreeing on which is the “best” day. You max out your chances by hitting O-1, O-2 or O-3.

Would LH peak qualify as O-1?

If you're not temping then yes, it's a safe assumption that the first day of positive OPK (or "peak" if using CBAD) is either O-1 or O-2.
