But if you can overcall at the 3-level after your LHO has anounced a strong balanced hand, surely you can also open at the 2-level. In fact, opening at the 4-level may well be safer than overcalling at the 3-level. And also disrupts more.
The 3-level overcall doesn't disrupt at all and should on this board have made it easier for opps to find the slam since East now got to show the fit immediately, which would probably not have happened if you had passed. So I think that on this board it was Wests pessimism and not your overcall that gave you a good score.
The overcall can help partner find a sac (they might bid 6♠ over opps 6♥) or find the spade lead. A 2♠ opening is much safer and also more likely to be effective.
At the first and second seat, I can't preempt freely unless I hold the exact length and trump holding, because if my partner wants to investigate slam, he has to know exactly what I have from his hand and my only bid.
For example, auctions such as 2
♠ - pass - 6
♠ - all pass is only possible when the 2
♠ opening is well defined in both length and quality. Therefore, I never preempt with a void (unless overcalling the void) or with a side suit (5-card suit or good 4-card major) when my partner hasn't passed yet. The way I usually bid slam is just by simple math (for NT slams, e.g. if I hold 13 HCP when my partner opens 2NT, it is a direct raise to 6NT), or by constructing possible hands by partner and counting tricks (for suit slams, e.g. if partner opens 2
♠, I hold
♠AJTx
♥AKQ87
♦KQ97
♣, it is a direct raise to 6
♠ because the opener must have the trump KQ to qualify for a 1st-seat opening - even though it is possible to find 7
♠ if there is a method to query the
♦A as there is a risk that the 4th seat can find their
♣ fit and interfere with our constructive methods), rather than any constructive methods.
