I pass both hands.
In most of my partnerships a 4th seat weak 2 shows a minimum range opening bid with a fair to good suit. I lack either quality.
I would open only if someone had stolen my partner's bidding box......opening has a lot more going for it when partner isn't allowed to bid. As it is, partner rates to hold a stronger hand, in hcp, than I do and may not appreciate turning a pass-out into a minus at the 3 or 4 level.
I was trained as an engineer and my calculations in my previous post indicates that approx. 55% of time we will go plus if I open 1
♠ even if system dictates a pass if partner doesn't raise. See previous post in this thread.

On the second one, at least our hand may be as strong as partner's but we have very bad honour location, and a rebid issue over almost anything partner bids, even if the opps stay out.
If he bids 1♦ we bid 1♠, I assume, and we have now bid our two best suits, in which we hold a grand total of 3 hcp.
If he bids 1♥, we have to pass, and now we could be in a silly 4-3 fit, and could be missing a 4-4 spade fit.
If he bids 1N, we are probably not going to like seeing a diamond lead, unless we decide to rebid (!) our bad 5 card suit.
There seem to be a lot of ways to get to a bad contract if we open....
On the other hand we have good intermediates, and 2 1/2 quick tricks, above average for a minimum opening bid in first position. Marty Bergen rates the hand an opening according to the rule of 20 after adding 1 point for the two tens in 3 card or longer suits with higher honors. Kaplan rated it a 13.10 on his Kaplan and Rubens points, the equivalent of about 14 goren points. Since it has 1/2 quick trick more than the minimum 2 QT he might upgrade this one point to the minimum 14 required for one of a minor in KS. I don't think it's worth another point upgrade for the spade suit because the spade suit is horrid. According to Ron Klinger even without the good intermediates this is an opening bid--at equal vulnerability he opens according to the rule of 21 1/2 with 10 hcp + 9 cards in two longest suits + 2 1/2 QTs.
According to modern styles these authorities are not light openers. Marty Bergen probably opens about 1/10 of a point below traditional BWS standards, Klinger .6 point.
By the way I play Walsh so if partner responds 1
♦ he promises either reversing values or no biddable 4 card major. My rebid of one spade promises an unbalanced hand with at least 5 clubs. If we are unlucky partner will have a balanced hand with 11 hcp and a
♥ stopper and jump to 2NT, if he has 12 HCPs it is less likely we are too high at 2NT. Similarly if he rebids one NT with 8 or 9 hcp we are slightly outgunned, only if he has 10 hcp do we have the strength advantage 20-20 hcp but we have at least 3 connected tens in longish suits.
If partner responds 1
♥ with partner's expected value of 10 hcp and our 10 hcp and the majority of the trumps and 95% chance of a ruffing trick in the short hand we have a very good chance of a plus score if they leave us in that contract, even if we end up in a 4-3 fit at this level. Even if we miss 4-4 spades we will still beat pass out if we're plus. If they intervene with a TO double we can explore the spade fit at the one level. More likely they will balance in diamonds, to which we will raise to 2
♥ which is still likely plus, If they go to three diamonds responder will look at his lengths and values in the red suits and be able to make an informed decision based on opener's first round pass. The extra 1/2 quick trick should compensate for the diamond shortness in opener.
If partner responds 1
♠ we can again pass if they fail to interfere, with even higher assurance of a plus score. By the law of total tricks we are legal to at least the 2 level if responder has 4, unless there are extra trumps, we again can defend at the three level, with high chance of a plus score.
If partner responds 1NT we know he lacks a biddable major suit and presumably lacks 5 card minor, thus a 99% chance of an 8 card club fit. Opener's rebid of 2 clubs is automatic. Responder again is captain, although if they try spades opener can suggest a penalty double at the 2 level.
If responder shows LR strength, no biddable majors, and 4 clubs by a 2
♣ raise and they fail to compete we have reached a good part score with a low chance of game and again will pass. We have at least a 9 card fit so we should tend to bid to the three level and defend at the three level if they overcall the level. A penalty double at the three level is very possible.
If responder makes a weak jump raise, we can hope to make it. Despite the 10 trump if they interfere it may be best to defend.
If responder makes a 2NT response it is probably best to retreat to the implied club fit.
Opening in first or second seat with such an unbalanced hand raises more complex issues. Since we have minimum values for NT we again maybe understrength if he raises in NT, and again if he has a minimum we may be slightly an underdog. Since a possible pass out is unlikely on the duplicated boards, an absolute plus or minus doesn't matter, just the relative scores. Since we must respect the forces if responder is unlimited there is a much better chance we will get too high when responder has a limit NT response or rebid, we have slightly more than a minimum if we find an 8 card fit in spades, hearts, or clubs. Our singleton means that we have a probable game if partner also has a 7 losing trick count. Unless partner has three spade honors, the spade game will not usually make if spades do not split 3-2 if we have exactly a 4-4 fit. Another way of winning is if the defending bidders play in NT. Opening leader will know that opener's better minor is probably clubs, and that he probably has no 5 card suit other than clubs. This will often stop a opening diamond lead, and provide key info for later in the defense when dummy is visible.
