Another example of cheating. *- round 4.

Although for most of the game there are no signs of obvious cheating in the opponents passing. On round 4 one bomb was made by a suspicious pass of a 6 from * when he/she could have passed a 7,8,9. They had very little else that round as my partner and I had all four aces, phoenix and dragon which could have got us the 400 points. A significant change in the game situationas we were then losing by 120 points in a 500 point game.

Another example of cheating.* - round 4.

Although for most of the game there are no signs of obvious cheating in the opponents passing. On round 4 one bomb was made by a suspicious pass of a 6 from * when he/she could have passed a 7,8,9. They had very little else that round as my partner and I had all four aces, phoenix and dragon which could have got us the 400 points.

No reason to suspect cheating. The partners have never played together before in a combined 223 games. Their passing success by the any combo made and best combo/pass made metrics is well below average.

Combos including bombs happen by chance. In this game, they made 1 of 3 possible bombs for a 33% success rate compared with the average of 11%. The probability of this happening is 29.5%. Given the extremely small sample of only 3 bomb opportunities, you’d expect the success rate to fall in line with the average if more rounds/games were played (regress to the mean). The passed bomb resulted from being given the lowest single remaining after pair split between opponents. The passer follows the same pattern on other rounds that doesn’t result in anything. No reason to see this as anything other than chance.

In 7 rounds, 14 opportunities for optimal passing but by my count they only hit 4 in total which is a success rate of 29% compared with the average of 50%. The probability of this occurring is 97%. Of those 4 successes, only 2 were the most optimal passes for a success rate of 14.3% compared with the average of 17%

You loss here appears to be a case of bad luck.

• #009 * and * pass each other an A for no benefit. * hand was P2223TTJJJQQQA before the pass. They elected to pass J 3 to opponents, likely hoping to get fourth 2 in pass. If they had kept the 3 jacks and passed phoenix to *, * could have passed J for QUAD BOMB and use the P to replace the missing J. This is the type of thing cheaters do regularly. As is, neither pass improved the other’s hand or created a combo: 0 for 2 opportunities.

• #086 * passes highest card K to partner, resulting in trips. However, it would have been better to pass unneeded 5 to * for gap in M234-67 straight. Instead, * opted to keep 33466 and pass away 7 2, possibly thinking it better to keep pairs than risk not getting passed a 5. * passed 7 went to * for no gain. Alternatively, Spicy could have passed the spare 4 which would have given * a QUAD BOMB. 1 for 4 opportunities; 0 for 4 most optimal pass; 0 for 2 bombs.

• #161 * passes 2 3 to opponents and Dragon to *. Given that their hand was mostly garbage, I’d say this was the best option. However, since * ended up passing * Mahjong, it would have been better for * to keep 2345 and play as straight. Another, perhaps better option would have been for * to keep M, * keep Dragon and pass 2 to * for gap in M-3456 straight. * already had PTQQAAA so Double Victory could have been the result if * hand was weakened by the pass. 1 for 6 opportunities; 0 for 6 most optimal pass; 0 for 2 bombs.

• #244 * is dealt 89TJQK flush bomb and has Dog 2236789 left; they keep the 2s, passed Dog 3 to opponents and lowest remaining single to partner. * passes J for no benefit. It would have been better for * to pass a card that’d pair with one of * singles and increase chances of early exit, maybe the 7 or 2 given to opponents. The last thing * needed was another low/mid single. 2 for 8 opportunities; 1 for 8 most optimal pass; 1 for 3 bombs.

• #319 The two swap A and Dragon for no real benefit, though it gives * a pair of Aces. If * had kept A and passed the 2 given to opp instead, it would have given * trips then quads with opp’s pass of other 2. Alternatively, * passed their 2, breaking a 23456 straight so as to not pass high to opponents and probably planning to use phx and extend through 8. It would have been better to pass the 8 or instead or * pass replacement. 3 for 10 opportunities; 1 for 10 most optimal pass; 1 for 3 bombs.

• #403 * passes K and * passes 9, both for no benefit. * could have passed single Q or A for trips, * could have passes 2 or J for trips. 3 for 12 opportunities; 1 for 12 most optimal pass; 1 for 3 bombs.

• #463 * passes A for trips though arguably K would have been better to fill gap in TJQ-A straight, freeing up * Phoenix for other uses. * passes 2s to opponent and lowest remaining single 7 (same pattern as when the bomb was made) for no benefit. * passes 7 for no benefit. 4 for 14 opportunities; 2 for 14 most optimal pass; 1 for 3 bombs.
