OTD
T1: land, land
T2: bear, dotow
T3: bear attacks
If you block and trade, then the bears make the same attack next turn before you can untap R. You can force the draw, but if you wait to untap then you can't ever win. The bears are ahead in the race, and won't ever have to block. If you don't attack, then neither do they, and you stare. If you attack, they attack back and kill you a turn before you kill them.
If instead you don't block on turn 2, then you're still down in the life total race, and the bears can just sit back and wait for you to attack. Whenever you do attack, the bears double block a single DotOW, take 2 damage, and now it's 18 to 18 with one creature for each of you, and they can win that race too. And again, if you opt not to race, then they don't attack either.
The 1 life you can gain from a land is enough to change the math by a turn, so now the onus is on the bears to attack or lose the race, and you get favorable blocks.
