On that first hand you need to call the river bet, betting the flop and then checking both the turn and river is going to induce a bluff, simply because he bets does not mean he hit a flush.

Second hand Im going to raise a little more preflop, probably closer to $15, thats a really weak bet on the flop, less than half the pot [probably closer to half after the rake though], Id definitely bet more here. Betting more on the flop would make a turn push much less awkward.

First hand:Bet turn and check fold river.

Second hand:Reraise more preflop

Bet more on flop

Push turn.
