well, i don't know what your rating is, but, regardless of that, i can't imagine
that you would always see such stuff (no offense intended!). in my own failures
to see simple tactics i have found some patterns. for example, i often fall into
a deep think in a position, and calculate a long variation. then, i play it out
rather fast. i try to think again after my opponent has moved, but hey, i
already calculated it and if i only have 10 minutes left on the clock for the
whole game, i might feel pressed to move fast. so i play the move i had
calculated 3 moves before, and suddenly see that there was something else...
another typical mistake is that you see a good variation and stop looking for
more. in your example, i could imagine sitting at the board and thinking:

[d]r1b5/p2k1r1p/3P2pP/1ppR4/2P2p2/2P5/P1B4P/4R1K1 w - - bm Bxg6;

hmm, this is looking good... do i have a safe continuation?
lets see 1.Re7+ Rxe7 2.de7 Kxe7 3.Rxc5 (menacing cb5 with a comfortable
advantage), so bc4 4.Rc7+, now if K moves 5.Rxh7, so 4...Bd7 instead 5. Ba4 Rd8
6. Rxa7, hmm, black might free himself with Ke6. so back to 4. Rxc4, that would
menace Rxf4 and Rc7+, ok, so i'm just a pawn up. hey, only ten minutes left, but
i get an ending with a pawn more - let's do it.
BTW, another continuation you might look at in that position is 1. Bd1 with the
menace Bg4+. that looks very dangerous for black too...
