My partner opened 1NT and I was planning to pass with 3 points and 4 small spades. Before I did, however, RHO overcalled 2 diamonds. I had 2 small diamonds and passed the bid around to my partner, who doubled. When it came back to me, I passed. I assumed this was a penalty double, since we play mirror doubles and I could have handled any positive response on the first round if I had the values. They made an overtrick and I was in the dog house with partner who said the double was for takeout. He didn’t want to sell out to 2 diamonds and wanted my input. He said I should have bid 2 spades. I argued that my pass told the story of my hand and if he wanted to take the contract, he should have just bid something. Anybody have an opnion?

It's normal to play this double is takeout. The reason is that the opener, who is already very limited, is unlikely to have a pure penalty double opposite a partner who couldn't bid over 2♦. In fact, even if he does have a pure penalty double, he is reasonably happy to pass, since the opponents are probably already in a bad spot.

However if he has a diamond doubleton (which is also much more frequent than a penalty double!), then it is usually right to compete. Maybe this will push the opponents up a level, maybe partner can convert the double with a reasonable hand and some diamonds, maybe the best spot is for you to just take a shot at 2M or 3♣.

I think penalty doubles where the old style on this position, but on modern bridge everyone is playing take out now.

There are not enough hands (if any at all) that partner would open 1NT and that can bring opps 2♦ down single handed. Since you showed "nothing".
I suggest you try to build one, and remember that the opponent must be able to bid 2♦ with what's left.

Opener's double here is just trying to compete for the hand, and is also likely if you play negative doubles.

When you have 3 hcp it is really unlikely that opener can want to defend 2♦x.

I'm sorry, but perhaps it is differences in language, but I don't know what a mirror double is.

'standard' has been, at least in NA, that 1N (bid) P (P) x was takeout and 1N (p) P (bid) x is penalty.

The reasoning is that opener is limited both in strength and suit length, so even a maximumm hand can't be sure of taking 6 tricks if in front of the overcaller, but it is far more likely to have 'sure' tricks with the same hand behind the overcaller. Imagine a trump suit of AQ108 over the bidder, then in front of the bidder...

I don't agree with this second statement (that it is standard, or that it is logical). Partner's double in the balancing seat is takeout, and I am happy to just defend undoubled if partner doesn't have the values to make a takeout double. Meanwhile, I think it's obvious that if I am 4423 and it goes 1n p p 2♦, I should be able to compete.

I am going to guess that you play negative doubles at the 2-level, which is a fairly recent trend, and in that case, all doubles are takeout. Traditionally, doubles of 2-level overcalls were penalty. I agree (if I am correct in my assumption) that negative doubles are a good thing here, and they may now be expert standard, but they certainly did not use to be. My post was in the context of what I think is still taught by some as standard.. the old fashioned way.
