I don't know who Andrew is but I am either doing something fundamentally wrong or going through an extreme example of random clustering. According to Pianola, over the last three months (12 sessions) I have defended on 87% of hands. This compares to 82% over the last 12 months.
If this is correct, then it is extremely likely that you, your partners, or probably both are far too conservative
You post a lot of very poor results, usually the result of your partner knowing very little about how to play. Occasionally, as here, you post examples of being fixed by the opps. Everyone gets fixed by the opps on occasion, but usually that sort of misbidding and/or misplay should result in a good board for your side.
There’s no way to diagnose why or where you and/or your partners are screwing up in the bidding as often as it appears you must be: not without seeing the hand records and the auctions for every board during those 12 sessions. Given that you have posted, ever since I recall you posting here, that you routinely defend far more than your share of boards, I am as certain as I can be, without that analysis, that you and/or partner are creating this situation. Not on every board, of course, but over the course of the session probably missing two or three opportunities to be declarer, to your benefit.
To give you an example of why I come to that view, many years ago, when I was a fairly good (in context) player playing club and sectional games with a regular partner, I did track declaring and defending frequencies. We defended roughly 45% of boards over about a year (I’d estimate 60 sessions or so) and I declared about 28% of the time and my partner a tiny fraction less. We lived in a small city, hundreds of miles from any major centre, so the bridge wasn’t strong and we won more often than not. I only say this to show that we weren’t hogging the hands at the cost of getting bad results
I haven’t done that sort of analysis for a very long time so I have only impressions of frequencies these days. However, in my regular partnerships we open light, respond on air, preempt aggressively and so on. So, except when playing serious events against experts (most of whom do the same), I suspect we defend no more than 45% of the time.
I’m not offering to do a big analysis but if you had records from one session where the average hcp were approximately equal, averaged over tge session, yet you defended more than 65% of the time, I’m virtually certain I’d find issues that you and/or partner could work on.
