Two hands from LIVE 5k max-buy in private home game

[dlpnyc21]

In hand 1, I decided to raise to 1700, which was a really bad raise in retrospect because I should have just made a huge raise to show him I was never folding and therefore had more FE. He deliberated for not too long and shoved, I had to call and I didn't suck out vs. his KK.

Hand 2: I decided I was beating a flush and he might call off with a flush in this range. He tanked it, stood up from the table, counted the pot, and after about 5 minutes he called with A3, value shove no good.

I think hand 1 is mostly a call, or if I raise it, I should raise bigger in order to conteract the perception that he has FE.

In hand 2, I guess the river is a raise vs. his range, especially since we just got there and the proverbial "wheels" have come off the game.
