Giveaway chess: the 1.e3 theorem: proven that white does not win after 1.e3

Some posts or info that come up say that 1.e3 in giveaway chess is safe for white. Some even say 1.e3 is a win for white. At first glance, it might not seem obvious that BLACK instead wins after white's first move of 1.e3. Here's how.

When black captures a piece, you simply take the rook with the bishop. The white bishop has to keep taking pieces while your queen eventually gets sacrificed, leading to a winning endgame.

This is the suicide defense, and with best play it is a loss for black.
