Hand reading 201, part 1

[The_Bends]

A) Looks like a set to me, his bets suggest he wants you in the hand and it fits perfectly with how he's played the hand so far. AJs also looks possible

B)QQ, 33, 22, JJ, AKs, AJs, AQ?, QJ?, 45s??, KK??, AA??? Seems like 45s would play the flop stronger. AQ probably wouldn't lead the turn, QJ seems like an odd preflop call. AA and KK seem unlicky without a preflop raise but not impossible. All the rest of the hand I think are plausable.

C)So pot would be 350 with 400 to call. Given those odds, AJs can't call because he can eliminate you having a flush draw. AKs can't call either and AQ has to fold, 45s just can't call. All the sets can call KK probably has to fold while AA can call. QJ can also call.
