"The problem with hands like these is that as they contain three features,they really need three bids to convey their content.
In systems like Acol,when you can't freely bid two different 4 card suits,a considerable amount of fibbing is then involved.
The result of all this is you frequently end up in 4-3 trump fits(having to ruff in your own hand) and hopeless misfit NT contracts
short on points.
The solution is a simple one DON'T OPEN THE BIDDING WITH THIS DISTRIBUTION WITH ONLY 12 OR 13 POINTS
Let's say you open 1♥and partner responds 1♠(there is no problem if he bids anything else) In Acol you're stuck
If you play strong NT with 5 card majors and open a minor suit and get a 1♠ reply all you can do now is re-bid 1NT
This is a sure way of going down,possibly doubled,whenever partner is weak.
Just pass. If partner bids,you will be back in action. If he bids 1♠ on a minimum opener,you will now stay out
of a dodgy Game you couldn't have avoided had you opened,if he bids anything else you can get excited.
If an opponent opens 1♠,you have an ideal 2nd round double. If they bid anything else then you know that your pass was justified.
In the long run you will find yourself staying out of all these horrid contracts you wish you hadn't been faced with
With 14+ points, if partner bids your singleton you can re-bid NTs without risking so much.
The down side? A few missed part scores. Missing Game is impossible. If partner can't bid,what contract can you possibly miss?"
