This is the position from last week
This is actually an excellent deal. We get back our empty column and have no less than four guaranteed turnovers (Well done to Bart for spotting this). But before we get too excited, let us think in terms of our old friend: Maslow’s Hierarchy of Wants:
We have no problem with turnovers and legal moves. We have one empty column, and a decent chance of another if the last face-down card in column 7 is favourable. We only have to remember to clear column 6 before turning over the last card in column 7, otherwise any bad card would be rather embarrassing!
We don’t have a lot of in-suit builds – but at least we can easily obtain a number of in-suit builds in addition to those we already have. We should also check whether it’s possible to remove a complete suit. With so many face-down cards remaining we expect to hear the bzzzzzzt sound – and sure enough none of the four possible suits are close.
Maslow’s Hierarchy of Wants tells us we should be looking at getting more in-suit builds and empty columns. However (as I alluded to earlier), we should not be focusing entirely on a single layer – our main thoughts are getting more in-suit builds but bearing in mind other layers e.g. (1) making sure we do get at least four turnovers (2) increase flexibility by playing non-reversible moves at the last possible moment etc.
We get the Queen of Spades. This gives us a second column but counterfeits the possible turnover in column 1 since we no longer have a spare King to access the Eight of Clubs in column 10.
We could turnover Column 2 without losing an empty column but costs a lot of flexibility since we commit to Jack-on-Queen, Six-on-Seven, Eight-on-Nine and finally Ace-on-Two. Instead I chose to turnover column 1, giving up the second empty column. Note that we should dump the 7-6-5 straight into the empty column since we can always shift the Queen of Diamonds in column 10 into the other empty column and expose the Eight, winning back an empty column. The advantage becomes apparent if we reveal an Eight of any suit. In fact we very nearly get an Eight – alas I can only count Seven pips in Spades.
We next turnover column 2, taking care to dump the Ace into the empty column. We can always get it back with the Deuce of Spades in column 5. We get the Jack of Diamonds.
We could take another immediate turn-over in column 2, but then we would lose the opportunity to exchange the 7-6-5 of Clubs and Queen of Diamonds in columns 7 and 10. Therefore we get back our empty column and exchange cards in columns 7 and 10 as described above. This is not likely to cost since there are two Sevens in columns 1 and 7.
The next card is the Queen of Clubs.
We only managed to increase our four guaranteed turnovers to a measly five. But at least we’ve managed to gain some in-suit builds as predicted. It’s time to bid adios to our empty column, assuming the next card also rot13(fhpxf). This means any last-minute tidying up that we tried to delay (to increase flexibility) must therefore be done now.
How would you continue?
BONUS QUESTION: With 20-20 hindsight, I think the Noble Spider GM has goofed. But let us pretend for a moment the Grand Master deliberately goofed to give the student an opportunity to test his or her critical thinking skills. Why do I say the Noble Spider GM has goofed?
