#1 I dont like barreling into people who seem unlikely to fold, particularly with FDs/T9 getting there and no overcard to Qx rolling off. 42/17/1.1 means you should value bet that guy, not barrel three streets into him on 3 clean outs. River sizing is also too small to get him off Qx.

#2 Preflop fold > 3b > call imo. Postflop seems okay.
