Two lead posers from the match.
 
1.  The enemy vulnerable, and playing a 3-weak two system, bid: -
 
(2C)  (2D)  /  (3D)  (3S)  /  (4C)  (4H)  /  (4N)  (5S)  /  (7D) End
 
All big hands opened (2C) with a relay (2D), followed by 3 natural bids. (4H) was grey ( suit, values, Qbid ?. (4N)RKCB ( with neither player knowing what was 'agreed' ) (5S) showed 2 Aces ( of 5, including the agreed suit King ) plus 'agreed' trump Queen.
 
You, to lead, hold: -  J965  J965  65  J92
 
2.  Nobody vulnerable, the enemy ( 5-card Majors ) bid: -
 
(1H)  (2C)  /  (2N)  (3N)  End
 
(2N) 15-19.
 
You, to lead, hold: -  Q32  J875  QJ97  92
 
This is what happened ( ! )
 
1.  In a Grand Slam the "expert" advice is to lead a trump, however I felt that one of the major suits might be more productive, and after some thought I "tried" H5 - which did not cut the mustard ( -2140, note that the "expert" would have gone for the same score! ). In the cold light of day I think that I overloooked a point: if (4H) was a Qbid, then S5 may have been a better choice! Losing 13 imps
 
3  void  AKQJT82  AKQ65
KQT87  AKT4  97  T4
 
At the other table: -  ACOL (4N)  (5H) ACE  /  (6D)  End
 
2.  The "normal" lead might well be DQ, but I thought a bit about the bidding. My LHO opponent doesn't hold 4 Spades, and if my RHO was top end with 4.5 Majors then he might have patterned out with (3S) so I "tried" S2. Adrian won wth SA ( S9 from decalerer ) and continued SK ( allowing for a lead from J32 ) SJ, and I unblocked SQ, for Adrian to cash 4 more Spades.
 
T7  Q3  AT32  A7654

At the other table ( with Spades bid ) there was no accident (4H=). Gaining 11 imps
