If you have been following our series on End Plays, you appreciate that in some situations finesses and repeated finesses do not always generate the most tricks.
In Part 3 of our continuing saga on End Plays, we will generalize our understanding of similar hand patterns and principles.

Okay, the results are in on our End Play poll where we ask which is true:
.
0 percent: End Play odds with AJ9..and..xxx are the same as AJ10..and..xxx w/o End Play
18 percent: End Play odds to make 1 trick go up over 20% when holding QJx..and..xxx
13 percent: Both of the above
18 percent: Odds for End Play finesse scenarios go up with most all split honor combinations
50 percent: All of the above
.
Everyone seemed to be in agreement that the odds are indeed the same when the secondary honors are split and you can execute an end play – good for you!
.
The next three responses seem to be a bit tricky for many, splitting 50 percent for one of the three choices and the remaining 50 percent accepting all responses as being correct. Regardless of the numerical values associated with a given end play tactic, suffice it to say it’s most important just to be aware that when making a finesse is questionable, it’s often best to instead consider making an end play to gain an advantage. In fact, sometimes when the opponents’ hands are imbalanced, it turns out you may get an unexpected ruff and sluff or opponents do not properly defend against your tenace cards.

Yes the last hand was not an end-play at all as the play did not force opponents to make a loosing lead.
It was just a case of repeated finesse that would succeed in ~55% of the time.
