Caveat: I don't know the opponents, but I'll take it they're tricky lags.
Hand 1: I think check-call is the river play, but bet-call might be better. Will he call with the straight - probably, but he'd also raise with the flush which you'd have to call. The flush is more likely than the straight, so I think check-call is a slight favorite here.

Hand 2: weak ace, any king or queen will surely call here. So I like it.
