Hand 1: Bad! You neither have the odds to call, nor any fold equity when you shove so little. I would check the turn, hoping his bet is in the 50ish range, and we can call if we expect to be able to get stacks in on a
OTR, or crai with better FE if we don't think he will pay off our flush.
Hand 2: Bad also! As played, I think you're beat OTT, BUT, we need to back this hand up a bit. Now, you call the raise preflop b/c you have a multiway pot brewing and we wanna stack somebody with our flush, right? OK, fine so far. Now, flop comes with a paired board. Why are we calling the flop bet (again, to hit our flush) when
we immediately fold when we hit it? If we are so worried that Nitty McNitterson is still in the hand that we will fold our flush when we hit it, then we need to fold OTF. If we are calling the flop bet to hit our flush, AND have McNitterson fold (and we are OOP to him), we are just lighting money on fire. You need to either fold to this flop bet OR raise pretty large, say to about 100 here, we want Nitty out, or we are done. As played, we passively pissed away 26BB, or about our profit for the next 2 and a half hours.
