Load the same PBN practice boards used by Test your Leads, choose High–Low or McKenney signalling, then practise communicating with partner during the play.

Teaching Signals
Decide what information partner needs before deciding which card carries the message.
High–Low
Attitude: a relatively high spot encourages; a low spot discourages.
Count: high–low shows an even number; low–high shows an odd number when count is required.
Do not sacrifice a trick-winning card merely to make a textbook signal.
McKenney
Suit preference: a relatively high card asks for the higher-ranking relevant side suit; a low card asks for the lower-ranking one.
Exclude the suit being played and normally exclude trumps when deciding the two relevant side suits.
Use suit preference only when attitude or count is not the more useful message.
Signal hierarchy
First ask: attitude, count or suit preference?
Then identify what partner needs to know from the auction, lead and visible cards.
Only then choose the signalling card.
Loaded boards
If a PBN contains Contract and Declarer tags, the app uses them.
The deal is rotated on screen so declarer is South, dummy North and opening leader West; the original compass seats are shown in the board information.
Without a contract tag, the app creates a practice trump suit from the longest N/S fit.
How to Play
Playing a trick
The highlighted player plays.
You must follow suit if able.
A trump beats a non-trump; otherwise the highest card of the suit led wins.
The winner leads the next trick.
Using the trainer
Select High–Low or McKenney once; the chooser then disappears and your selection remains in force while you move through the boards.
Declarer cannot make the opening lead: the app warns if South is clicked before West (declarer's LHO) has led.
Opponent cards are hidden by default; dummy and declarer are visible for teaching.
West makes the opening lead automatically. East and West are automatic defenders; declarer plays both the South hand and North (dummy).
The opening lead uses the same card-selection rules as Test your Leads. In No Trumps, low leads are explained in a popup, including the possibility of fourth-highest from an honour.
Only East and West are defenders and can make defensive signals; dummy and declarer cards are never labelled as attitude, count or McKenney signals.
The defenders use the selected signalling method and can act on partner's suit request.
The signal panel explains signalling opportunities and scores tested decisions.
All teaching explanations appear as popups; the top strip is status/score only.
When a defender makes a signal, the played card now shows a badge such as ENC, DISC, SUIT ♠, EVEN or ODD.
On suitable No Trump opening leads, the trainer identifies a finesse opportunity. If dummy plays low, East plays third hand realistically; the next popup tells declarer whether to finesse with the jack or cover the queen with the king.
If you click the wrong declarer or dummy card, use ↶ Undo card in the board controls or at the top-right of the table. It rewinds that play and any automatic defender response that followed it.
Use Previous/Next or the board selector to move through the loaded PBN.
On your first visit, a Getting Started modal explains the three main signal types and shows a quick example before you begin.
