David,
Congrats on your net success for the night! You seem to make the case eloquently for 2 horse wagering, even if only in cases when serious overlays or net mutuel prospects exist. Reading some latter Follow Ups lately, I recall Doc saying (yet again) how that method can be easier on the old psyche, and thus even more profitable in the long run. Of course if one's psyche is not fragile, then no need for that part of the safety net, and it's only a question of whether sometimes mutliple wagers, sometimes a single wager is long-run more profitable.
At the end of an evenings wagering, I think I'd have lost sleep over those final 2 losses, despite being up for the evening
yours,
Ted
