Evaluating and Playing our Hypothetical Hands on Sixth Street

The next round brings:

Andy

Bob

Chuck

Greg

Andy suddenly has a powerful hand, three Sevens, and he happily bets €8. Bob is pretty much positive his three Queens are still the best hand, and pauses. Should he raise, trying to drive out the drawing hands? Or should he call, and try to lure more players in? He decides to raise; in a game with seven cards, if enough players are out there drawing at straights and flushes, the chances become good that ONE of them will get there, even if the odds are against any one particular player doing so. The pot is already pretty big. Better to try to narrow the field, he decides; even if they all do call, he might win a big pot.

Bob would have preferred to "narrow the field" after the fifth card, because once players get to sixth street, they tend to stay until the end. The vagaries of position made it impossible to do this on fifth street, because Bob had to act first. On sixth street, Andy's open pair of Sevens changed the betting order, and his bet gave Bob the chance to raise and try to narrow the field.

Chuck is now staring at having to call €16. The three he needed fell just in front of him! Life is not fair! Still, he thinks there are three other Threes he can catch (he has forgotten about the Three that Ed folded earlier), and two other Eights (he doesn't know about the two Eights that Ed had in the hole). So Chuck calls, thinking there are five cards that can win for him, while actually there are only two.

Greg is a bit confused by Bob's raise. Probably Bob has a pair of Queens; possibly two pair. Greg's Kings might or might not be the best hand. But he can still catch another King, for trip Kings, or a Ten for a straight, or perhaps an Eight or a Jack, for two pair. He also calls.
Andy, whose eyes had lit up when he caught the third Seven, is now a bit confused. Not only was his bet called, but it was also raised and called! He is tempted to raise again, but wonders. Chuck could have a flush or a straight. Bob could have three Queens, or a flush draw. Greg could have three Kings or a straight. He decides that there are too many possible good hands out there against him, and just calls. He can always bet more if he makes a full house on the last card, he realizes. The €64 added to the pot brings it to a total of €161.
