In Response To: Money game: Blue to play 4-2 (Timothy Chow)

OTB, I thought White's board was too strong to warrant leaving a direct shot. Indeed, lift White's blot to White's 3-point and the decision is very close. But the blot is a liability; only 2-1 hits and covers, and after 2-2 and 4-2 White probably has better plays than lifting the blot. Making Blue's board is easily worth the direct shot it leaves.
