OK Mark, this is how I play these hands:

#1: 66677889TQKKA
66677 QT977 KKA I think the A kicker is very important, so I sacrifice the middle. I really want to see the result of playing 66677 AQT98 KK8

#2: 289JKA 2239JQQ
Here I play AKJ98 [img]/images/graemlins/heart.gif[/img] QQJ93 222 giving up in the middle.

#3: 6TJQA 345579TA
TT55J 34679 AAQ

#4: 348TJK 244667A
KJT84 [img]/images/graemlins/heart.gif[/img] 23467 A64

#5: 45JQA 2347889Q
This is the most difficult one for me. I decided for:
QQ884 23457 AJ9
But very close to me is: AQJ54 [img]/images/graemlins/club.gif[/img] 97432 88K

#6: 23468K 22358TT
222TT 86543 K83
I believe is close 22238 86543 TTK

#1: 66677 89TQA 8KK is best, scoring about -0.03 points. 66688 779TQ KKA is only slightly worse, about -0.10. (12087 samples.)

#2: AKJ98-flush 39JQQ 222 is correct, scoring about -0.02 points. Next best-alternative, AKJ92-flush 2389K 2QQ, is about -0.37. (12060 samples)

#3: 55TTJ 34679 QAA is correct, about -0.01. (11901 sample hands)

#4: KJT84-flush 23467 A64 is correct, around -0.01. 38TJK-flush 2667A 444 comes in at -0.34.

#5: I thought this one was easy, AQJ54-flush 23479 88Q is best, a little less than +0.01. (12027 sample hands) AQJ54-flush 23478 89Q is actually the second-best at -0.37 with 49JQQ 23457 88A a distant third at -0.79. QQ884 23457 9JA only scores -0.84.

#6: The best is to play the flush, 2368K-flush 23458 2TT, which scores about +0.02. 222TT 34568 38K is -0.08, 22238 34568 TTK is -0.68.

As should be obvious now, what the hands all have in common is that the best play is essentially break-even. (These were the hands closest to zero I could find in my 200K-hand sample, though going to 1M hands shows that some of the 'zeros' were off by +/- 0.15 points.)
