Typical game looks like this:
Player A rolled 2,2,4,4,6
Player B rolled 2,3,5,5,5
Dice on the table: 1,3,5,5,6
A: "1 two"
B: "1 three"
A: "1 four"
B; "1 five"
A: "1 six"
B: "2 threes" B avoided 2 ones and 2 twos and probably made a mistake, cause now A thinks B doesn't have 1, or 2 on his dice.
A: "2 fours"
B: "2 fives"
A: "2 sixes"
B: "3 threes" B plays safely, ensuring A that he is out of 1's and 2's
A: "3 fours"
B: "3 fives"
A: "3 sixes"
B: "4 twos" (B doesn't have any ones-1's on his dice, and there is only one "1" on the table - probability that A has 3 ones is small) A should call him a liar - B said "1 five", "2 fives" and "3 fives" so he is strong in fives, and now declared "4 twos" which he avoided in the past. But a sees 3 twos on the table, so if B has 2,5,5,X,X the game is lost. A should declare "4 fives" now, but A supposes B doesn't have any fives.
A: "4 threes"
B: "4 fives" (B is strong in fives - he has 3 fives, and there are 2 fives on the table, and maybe A has a five, so B is safe till "5 fives", or maybe "6-7 fives" if A has any fives.) This crossed A's plans to play "4 fours"
A: "4 sixes" B is almost sure that A is lying, because he doesn't suppose A has "3 sixes" among his five dice. Anyway, B decides to raise the bid to "5 fives"
B: "5 fives" A is feeling he's losing the game. B is playing fives, so A's strategy was bad. He has only two good options now: call B a liar, or play 6 fives.
A: "6 fives"
B: "LIAR!" B knows A hasn't played fives before, so he doesn't have any.

B wins the game.
